The first thing to check is that your TV is set to the best viewing mode. Flat-screen televisions offer different viewing modes – for example: normal mode, zoom mode and stretch mode, etc. Check that your TV is set to normal mode. Some manufacturers use other words to describe the viewing mode options, so please keep that in mind when finding the optimal viewing mode.</p> Also, the factory default setting for some flat-screen TVs may cut off the sides, top and bottom of the picture (an “overscan” mode).

How does it work & how do I use it?</a> <div class="expandContent pane"><p>Precip Start Stop is powered by a tool called Future Radar. Future Radar visualizes where rain is expected to originate and uses an algorithm to determine when precipitation is going to start and stop based on a given location. This updates every 10 minutes.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2a.

It will allow you to plan activities with a better idea of exactly when precipitation will fall, and levels of intensity as well. Since the product updates every 10 minutes it will prove to be valuable on the days with on-and-off precipitation because it uses radar and therefore will have a better estimate on when to expect that quick passing shower in your location.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2b. Should I be cautious when using Precip Start Stop? </a> <div class="expandContent pane"><p>While this product has a lot of benefits, there are certain limitations as well. Precip Start Stop will not know if a storm is expected to grow/dissipate or change in direction. Because it interprets any radar echo as real precipitation, there is a chance that some erroneous precipitation echoes will be interpreted as rain while some very light precipitation (like super light snow in the winter) won’t be detected by the radar. Finally, this product will only work in the areas where radar data is available, as determined by Environment Canada. Areas close to the edge of the radars might not get the most accurate information.

What locations get this information? </a> <div class="expandContent pane"><p>Any location that is covered by a radar network. Please refer to radar locations map provided in question 2b.

What kinds of precipitation are captured?</a> <div class="expandContent pane"><p>Yes, this product works any time of the year and it can detect any of the following precipitation types: rain, snow, freezing rain, ice pellets. While in real life it is possible to get multiple precipitation types all at the same time, this product will detect the most dominant precipitation type.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9.

Hourly forecasts are being produced by our meteorologists who interpret computer weather model data and use their knowledge and expertise to create a forecast. These forecasts are being updated at least twice per day and more if the forecast needs to be changed. Precip Start Stop is derived from a radar with some automated processing and is being updated every 10 minutes; hence, some differences are possible between the two products.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="forecast-information">Forecast Information<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle"> 1. How does The Weather Network create a local forecast?</a> <div class="expandContent pane"><p>Forecasting is complicated, and there’s a lot of pieces of data involved.</p><p><strong>Current Weather:</strong>The observations are a report of current weather conditions at a particular time and place. Many observations are recorded at airports across the country and are a combination of data from automated weather stations and information from meteorological technicians or weather observers. An increasing number of observations come from entirely automated weather stations. Observations are generally taken at least once an hour, at the top of each hour, in Canada and around the world. However, some weather stations augmented by weather observers report only during specific times (e.g., for military flight operations). Temperature, precipitation, opacity (sky coverage), pressure, dew point, visibility and ceiling can be reported in a weather observation. However, due to equipment differences, not all weather stations report all parameters.</p><p><strong>Forecast:</strong>The forecast is a look ahead at the expected conditions. The Weather Network’s local forecasts include a short term forecast, a long term forecast, and a 14-day trend. A short term forecast is a look at the next 24 hours broken into six-hour time blocks. The long term forecast is a look at the next two to seven days. The 14-day trend is an outlook of the expected maximum temperatures over a 14-day period compared to the average normal daily maximum. It is not unusual for the long term forecast to change daily.</p><p>The Weather Network provides both a daytime high temperature and a 24-hour minimum (or low) temperature for every day of the forecast. Usually, the highest temperature for a particular day will be achieved during the daylight hours and the lowest temperature will be during the night-time hours. However, this can change. If a warm front passes through overnight or a cold front moves through during the day, the highest or lowest temperature may occur at an unusual hour.</p><p>Probability of precipitation (POP) is one of the most misunderstood elements of any forecast. It is simply the chance that measurable precipitation will occur at a particular location over a given time period. Measurable precipitation means at least 0.2 mm of rain or the water equivalent of snow. The POP does not predict when, where or how much precipitation will occur. Therefore a POP of 30% means that there is a 3 in 10 chance that there will be measurable precipitation at the location. A POP of 100% means that the forecaster has a very high confidence that rain will fall at the forecast location. These high POP values are associated with very organized weather systems covering large areas of the country. On the other hand, thunderstorm forecasts are often associated with lower POP values such as 40%. In this case, there is a better chance that the location will stay dry vs. getting wet. People who can be flexible with their plans should not cancel outdoor activities, but must be ready to quickly take cover if a thunderstorm does develop.</p><p>A wind forecast includes direction and speed. The strength and direction of the wind is the result of pressure differences in the atmosphere which are caused by large areas of high and low pressure as well as local effects. On a surface weather map, the distance between the isobars (lines of equal atmospheric pressure) can be used to judge the strength of the wind – the closer the isobars, the stronger the wind. Generally, air circulates clockwise around high pressure and counter-clockwise around low pressure in the northern hemisphere. Although some local effects are taken into consideration when generating a wind forecast, winds can be affected by urban structures such as buildings. Urban structures are not considered when formulating a wind forecast for a particular city as wind speed and direction can vary significantly around a given building.</p><p>The humidex is an index which accounts for the combined effect of the temperature and humidity. The humidex is not a temperature, but attempts to give a value which reflects a person’s perception of discomfort when warm temperatures are coupled with moderate to high humidity. Generally, people begin to perceive the effects of temperature and humidity when the humidex exceeds a value of 29. The wind chill is an index which accounts for the cooling effect of the wind at low temperatures. The wind chill is not a temperature, but reflects the feeling of colder conditions when your skin is exposed to wind. The index was determined by comparing the rate of heat lost from a person’s face under different temperature and wind conditions. It gives an idea of the temperature under nearly calm conditions which would cause your face to feel the same cold sensation as the actual temperature and wind. It is important to understand that the wind chill is not a temperature, and that your skin, or any object, cannot be cooled below the actual air temperature. The wind chill is a calculation which appears on The Weather Network when the wind chill drops below 0.</p><p>The normal maximum or minimum temperature is an average daily high or low temperature for the time period and is based on an average of 30 years of data. The daily normal or mean temperature refers to the average of the daily maximum and minimum temperatures for a particular day, month or year based on 30 years of data.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2.

Why is there a difference in forecasts from The Weather Network and Environment Canada?</a> <div class="expandContent pane"><p>Forecasts that are prepared by different forecasters will sometimes vary. When looking at satellite, radar and computer model data, different people will interpret the data differently. Although meteorology is a physical science based on mathematics, the science is so complex that a number of outcomes are possible. It is akin to when two market analysts look at the economy, they may interpret historical information differently and predict varying outcomes. At The Weather Network, we employ more than 40 meteorologists working 24/7 to ensure that our forecasts are as accurate as possible.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. Why does the forecast change?</a> <div class="expandContent pane"><p>The Weather Network's forecasts are regularly updated during the day to ensure that Canadians have access to the most accurate, local forecasts for their planning needs. Using computer models, our team of professional meteorologists is always on the lookout to see if:</p><ul><li>weather systems are picking up pace, reducing speed or changing direction; </li><li>the moisture in the system is changing; </li><li>and whether the system is gathering strength or losing its intensity.</li></ul><p>When our meteorologists become aware of significant changes in the atmosphere, they will issue an updated forecast based on the recent developments.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. Why are there sometimes differences between weather warnings and forecasts?</a> <div class="expandContent pane"><p>Environment Canada weather warnings are based on a sudden change in weather systems and are short-lived. Forecasts are simply a look ahead at the expected conditions. Our meteorologists upgrade the forecasts according to the changes in weather.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. How can the forecast for my area suggest not to expect any precipitation from Thursday afternoon to Friday afternoon while at the same time having a snow squall warning that says we will get between 15-25 cm in that same time period?</a> <div class="expandContent pane"><p>Weather warnings are issued by Environment Canada. The Weather Network has separate forecasts from Environment Canada which are very local for each community. We use Canadian computer models to base our forecasts on, and two American models for comparison. Generally, a warning will be applied to a larger area than just your community, and it is possible to see some differences between our local forecast and the weather warning. Snowfall amounts within snow squalls are particularly difficult for meteorologists to forecast. If the wind shifts even a little bit, snow squalls and higher-than-expected snow amounts could occur, that weren’t predicted by the computer model or the forecaster. The local snow amounts can vary greatly depending on exactly where you are and which direction and speed the wind is blowing.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. What is the difference between partly cloudy and partly sunny?</a> <div class="expandContent pane"><p>These terms are often misunderstood. Forecasters have disagreed over the definition of "partly" for years; that's why it is not widely used. In forecasting sky conditions, meteorologists describe what percent of the sky, from horizon to horizon, rounded to the nearest 10, is expected to be covered by clouds. A sunny day is one when there are no clouds or only 10 percent of the sky is expected to have cloud. With 20 percent or 30 percent cloud cover, the forecast calls for mostly or mainly sunny, or sunny with cloudy periods. When more cloud than sun is forecast, say 70 to 80 percent cloud cover, it's mostly or mainly cloudy, or cloudy with clear periods, or cloudy with sunny breaks. When 90 percent or more of the full sky is covered by cloud then it's a cloudy or overcast sky. When it's about half cloud and half blue sky, the wording is “mix of sun and clouds” or “variable cloudiness”.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">8. What is the difference between a shower, a period of rain, a rain shower and a trace of rain?</a> <div class="expandContent pane"><p>The difference between rain and rain showers has to do with the duration of the event and cloud type involved. For rain, which can last from a few hours to days, the cloud formation has to be more stratiform (horizontal) in nature. That is not to say that convective events cannot be associated with areas of rain. Rain showers are usually short in duration, a few minutes to an hour and are the product of convective activity. You get rain only on cloudy days but can get showers on somewhat sunny days due to convective or bubbly cloud formations such as towering cumulus or cumulonimbus type clouds. The term “trace” is used for rainfall amounts of less than 0.2 mm – this amount of rain isn’t enough to completely wet pavement, and generally does not disrupt outdoor activities.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9. How often are weather observations taken?</a> <div class="expandContent pane"><p>Environment Canada holds agreements with the World Meteorological Organization (the world’s standardizing body for meteorology) to take observations once an hour in fair or quiet weather. When more severe weather, such as strong gusts, hail, or freezing rain comes in, the observations are taken as often as necessary to alert the public of sudden, dramatic weather changes.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">10. Why are sky conditions not available for some locations?</a> <div class="expandContent pane"><p>Weather observation sites at airports in Canada are operated by NAV Canada (the country's civil air navigation services provider) on behalf of Environment Canada. Generally, sky conditions are reported at these sites unless there has been a malfunction. Many weather stations not located at airports do not have the necessary instruments to record current precipitation and cloud conditions.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">11. How are meteorologists able to predict the amount of snow or rain that will fall?</a> <div class="expandContent pane"><p>The numerical forecast models used by meteorologists contain what is called QPF (quantitative precipitation forecast) information. This water equivalent can be converted to snowfall by use of certain mathematical formulas. Meteorologists also look at weather observations and use their experience to modify the quantitative precipitation forecast information from the computer models to produce the most accurate forecast of a snow or rain amount.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. Is the air pressure shown on the local forecasts a corrected figure or uncorrected? How do you convert one to the other?</a> <div class="expandContent pane"><p>The pressure on the local forecasts is corrected to reflect the mean sea level pressure. If you look at your barometer at home (unless you live at sea level), it will actually read at a lower pressure. The mean sea level pressure that we report is not the actual atmospheric (or “station”) pressure at a given location, but rather a calculated value of the pressure if that location were at sea level. It is meteorological convention to speak of pressure as a mean sea level pressure for comparative purposes. However, for any practical calculation at a given location, the actual station pressure would be used.</p><p>The reason we correct pressure readings to mean sea level is so that we can compare locations at different elevations more easily (an example of this would be a surface weather map showing isobars – these lines connect areas of equal mean sea level pressure and help us identify areas of high/low pressure). If we did not do this, it would be more difficult to judge the relative strength of an area of high or low pressure as the system moved from a high elevation mountainous region into a low elevation region.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="cold-weather">Cold weather <span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. Why is the coldest part of the day just after sunrise?</a> <div class="expandContent pane"><p>During the night-time hours, the atmosphere’s heat is lost to space and the earth cools. When the sun comes up, solar radiation is initially very weak since the sun is very low in the sky. Meanwhile, energy is still being lost to space. As a result, during the first few minutes after the sun rises the energy outgoing to space exceeds the energy incoming from the sun so the temperature continues to drop – reaching the daily low typically within about 15 to 30 minutes after sunrise. As the sun reaches a point slightly higher in the sky, the amount of incoming energy equals and then exceeds the amount of outgoing energy and the temperature begins to rise.</p><p>In perfectly clear and calm conditions, another effect may play a role in decreasing the temperature after sunrise. Thermometers generally measure air temperature a couple metres off the ground. On clear, calm nights, the layer of air closest to the ground may be noticeably colder that the air around the thermometer. As the sun begins heating the ground, this colder layer of air is stirred slightly and rises to the thermometer level.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. How can snow keep you warm?</a> <div class="expandContent pane"><p>Snow can keep you warm because it is one of the world's best insulating materials. Dry fluffy snow is about 95% air. With all the air spaces, snow prevents heat loss just like fiberglass insulation or styrofoam. The temperature contrast between the top and bottom of a snow layer is often striking. For example, on a cold night, at the top of a snow cover the air temperature might be -30°C or lower. With a snow pack of 40 cm, the ground temperature might be around -6°C, making a difference of nearly 25°C between the top and bottom of the snow cover.</p><p>Without the protection of snow, the ground would freeze solid and vegetation in some parts of Canada would not survive the winter. Small mammals like mice, squirrels, rabbits and hibernating insects are able to live cozily through periods of brutally cold temperatures. During snowstorms, large animals will tunnel into snow banks, thereby greatly decreasing the rate at which their bodies lose heat. In the same way, a covering of snow provides an insulating blanket on your flowerbeds and on your roof, holding heat in when the air temperature drops well below freezing.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. Is it too cold to go outside when the temperature is -12°C with the wind chill factor?</a> <div class="expandContent pane"><p>You can go out with a wind chill of -12°C. Just make sure you are properly dressed in a warm winter coat and that your hands, ears and head are properly covered from the wind and cold. You may want to try layering your clothing since it is one of the best ways to insulate your body.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. What freezes faster, hot water or cold water?</a> <div class="expandContent pane"><p>The answer to this seemingly simple question isn’t straightforward! While the exact reason isn’t fully understood, hot water can freeze faster than cold water under certain conditions. The effects of convection within the container and the ability for water to become supercooled (still remaining liquid at temperatures below freezing) are thought to play an important role in the cases where hot water freezes more quickly. However, additional factors such as the initial temperature of the water, shape and size of the containers, water purity and air temperature may all contribute to the outcome. You can try this experiment yourself by filling two ice cube trays with hot and cold water and putting them in your freezer. Because there are so many variables in this experiment, you may get different results than your neighbour!</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. If it's 3°C outside with a windchill factor of -8°C, will water freeze due to the windchill factor?</a> <div class="expandContent pane"><p>No. The freezing point of pure water is, as you know, 0°C. If the air temperature is not at or below this temperature, the water temperature will also remain above freezing and the water will not freeze. Water in an environment where the air is at 3°C cannot get colder than 3°C no matter what the wind is doing. In fact, even if the wind is howling and the water is already frozen the ice will melt and the water will warm to 3°C over time. The reason people and other warm blooded animals feel colder due to the wind is that we generate heat internally as we metabolize food and fat. When the wind is blowing and the temperatures are cold enough (as opposed to a hot summer day) our bodies lose this internally-generated heat as the air flowing around us carries the heat away. At a given temperature, the stronger the wind is the faster this heat loss occurs and the colder we feel. The wind does not actually make the air colder so it can not cause water to freeze if the temperature is above 0°C.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="satellite-and-radar">Satellite and radar<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. Why does the radar map almost always show precipitation over the same area, even when it is clear?</a> <div class="expandContent pane"><p>Radar stations located across Canada and the U.S.A. continually sweep the sky, sending out beams of microwave energy that bounce off precipitation particles. The radar antennae measure the amount of energy that is reflected back from these particles and we plot this information on a map as the precipitation intensity. However, energy sent out by the radar also bounces off the ground, buildings, bugs, mountains, etc. – we call these unintended targets “ground clutter” or just clutter. While it is possible to filter out most of this ground clutter, some of it will still be plotted on the radar map.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. Given the advent of radar- and satellite-based atmospheric measurements, do we still utilize individual weather station data?</a> <div class="expandContent pane"><p>Meteorologists continue to use surface weather stations because they are the best way to measure the conditions at a specific location. While all instruments are prone to some degree of error, the observations from a surface weather station are considered to be the best available. However, radar and satellite data is extremely valuable because it allows meteorologists to see the weather over vast areas where it is not possible to place surface weather stations. In weather forecasting, a mix of all data, both remotely sensed (radar and satellite) and in situ (weather stations) is critical to producing an accurate forecast.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. Why it is that sometimes the satellite image over Atlantic Canada looks quite ominous when there is very little precipitation – while at other times, it is indicative of a large low pressure system, typically a storm. Why the discrepancy?</a> <div class="expandContent pane"><p>Satellite images are snapshots of clouds and, depending on the weather situation, the clouds displayed may not produce precipitation that will fall to the earth. There are three primary types of satellite images used by meteorologists: visible, infrared and water vapour. Most often, the infrared satellite image is shown on weather maps. On an infrared image, the coldest and highest cloud tops are usually enhanced to draw our attention to these areas. Cold, high cloud tops are usually associated with large storm systems as well as thunderstorms, but can also be simply high cirrus clouds with no precipitation. Satellite imagery is a very important tool, but we need to use other tools such as radar, surface weather stations, and numerical computer models, to predict if a system will actually bring precipitation.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="precipitation">Precipitation <span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. How do you know if it is going to rain? What is meant by the “POP”?</a> <div class="expandContent pane"><p>Determining if it will rain depends on many factors such as a storm’s track, the amount of moisture the storm has, the speed of rising air in the storm, and the temperature before, during and after the storm. After analyzing these and other factors, the meteorologist then looks at the chance rain will occur. This chance is expressed as “Probability of Precipitation” (“POP”).</p><p>The POP does not predict when, where or how much precipitation will occur. Therefore a POP of 30 percent means that there is a three in 10 chance that there will be measurable precipitation at the location. A POP of 100 percent means that the forecaster has a very high confidence that rain will fall at the forecast location. High POP values are associated with very organized weather systems covering large areas of the country. On the other hand, thunderstorm forecasts are often associated with lower POP values such as 40 percent. In this case, there is a better chance that the location will stay dry. People who can be flexible with their plans should not cancel outdoor activities, but must be ready to quickly take cover if a thunderstorm does develop.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. Why does hail make its particular sound?</a> <div class="expandContent pane"><p>Hail’s particular sound is the combination of many hailstones falling through trees, on roofs and on the ground at some distance upwind from you. The mingled noises made by these fallen hailstones arrive to your ears ahead of the storm itself. Once the storm arrives where you are, the patter of individual stones drowns out the noise from distant hailstones, some two or three kilometres away.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. Are raindrops really tear-shaped?</a> <div class="expandContent pane"><p>Raindrops are shaped more like mushroom tops, round baseballs or hamburger buns. The falling speed of a raindrop is directly related to its size. Small drops, those less than 2 mm in diameter, tend to fall more slowly and remain round while larger raindrops, which fall more quickly, take on a more oblong shape due to the air pressure pushing up against the bottom of the drop.</p><p>In larger raindrops (more than 4.5 mm in diameter),the bottom of the raindrop encounters much greater air pressure than the top which will eventually cause the large drop to break apart into two smaller raindrops.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. Why are snowflakes quite big on certain days, and then smaller on other days?</a> <div class="expandContent pane"><p>The shape and size of an individual snowflake depends on the air temperature and the amount of water vapour available in the cloud where the snowflake forms. In very moist situations where snowflakes fall through a large depth of air near 0°C, the snowflake that reaches the ground can be a combination of dozens of matted-together smaller flakes. Snowflakes that form in drier conditions do not join together as easily and therefore, fall as individual smaller flakes.</p><p>Nearly anything can happen to a snowflake as it falls to the earth. These include pieces of a snowflake breaking off, evaporating into the atmosphere, and joining other falling snowflakes. Additionally, if the wind speed is too great, bigger flakes will be ripped apart and most of the snow will fall as smaller flakes.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. Can snow have different colours?</a> <div class="expandContent pane"><p>Snow can appear to be many different colours. Most often, it appears white due to the equal reflection of all wavelengths of sunlight off the ice crystals and air pockets within snow. However, snow can contain much more than ice and air. Pollen, single-celled organisms, specks of dust, dirt, sand, ash and traces of pollution are sometimes in sufficient quantities to affect the colour. Additionally, colonies made up of algae, fungi, and bacteria living among the crystals feed on the nutrients in the snow. Over the centuries, there have been reports of different coloured snowflakes from around the world. In 1818, Arctic explorer Sir John Ross discovered large deposits of red-coloured snow in Greenland. It was found to contain red-tinted, microscopic plants and animals. Yellow snow from can be created from pollen in a nearby pine forest; pink snow has fallen on Vancouver Island; and pale-blue snow has been seen in the French Alps – presumably coloured by copper salts in the dust from the Sahara desert. During the Dust Bowl in the 1930s, black and brown soils from Oklahoma and Texas turned snow non-white in many places throughout Eastern Canada.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Why does snow squeak when you walk on it?</a> <div class="expandContent pane"><p>The colder the temperature, the fluffier the snow and the squeakier the sound it makes when you walk on it. On cold days, when the temperature is -15°C or lower, there is less liquid water around the ice crystals to lubricate them as they move. Instead, when you step down, the individual cold ice crystals move abruptly, slipping and crashing into each other. The sudden rubbing or smashing produces that familiar cold-weather creaking sound. Because the sound produced by snow is related to how cold it is, you can use it to tell the temperature. The louder the snow noise, the colder the temperature of both the air and snow. When the snow cover is hard-packed or crusty, a distinctive crunching sound is heard when you step down. This crunching sound is caused by the breaking of strong bonds between ice grains within the snow pack.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. Which day is the snowiest?</a> <div class="expandContent pane"><p>Day-of-the-week variation in weather always produces lively discussion. Generally, there is little correlation between the day of the week and the likelihood of snow, or the amount of snowfall. Over time, the random nature of the timing of large weather systems will tend to make the chances of seeing snow equal for all days of the week.</p><p>Some studies in Australia and France have found variations in weekday vs. weekend weather. The theory is that increased air pollution on weekdays, especially in heavily populated areas, may alter the formation of precipitation by producing a greater abundance of condensation nuclei (particles that rain and snow form around). However, the impact is most likely very small, and would not significantly affect the amount of precipitation from large storm systems.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">8. What do you call it when snow evaporates before hitting the ground?</a> <div class="expandContent pane"><p>Virga is snow, or any precipitation that evaporates before hitting the ground.

When is it too warm to snow?</a> <div class="expandContent pane"><p>Generally, outside of mountainous regions, it is too warm to snow at 5°C. However, there are extreme cases where snow has been observed when the temperature is warmer than this. In these cases, there is a very shallow layer of warm air near the ground and the temperature decreases very rapidly going up (the clouds where the snow forms must be well below 0°C). The warm layer of air is not deep enough to completely melt the snowflakes before they reach the ground. If snow keeps falling for more than a few minutes, the temperature will usually fall quickly because of the heat being consumed by the melting snow.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">10. What determines whether precipitation will fall as freezing rain or snow?</a> <div class="expandContent pane"><p>Our atmosphere is composed of layers of air with different temperatures. So, air temperature at the earth's surface may be different from that above. What determines whether you get freezing rain, ice pellets, snow, or rain, is the thickness of warm and cold air over your region as well as the surface air temperature.</p><p>For example, freezing rain is possible when warm, moist air with temperatures above 0°C is sandwiched between two colder layers of air below 0°C. Precipitation from higher, colder levels begins falling as snow. As it falls through the warmer layer in between, the snow melts into raindrops. The warm layer should be over 1 km thick with temperatures above 0°C in order for the snow to melt. The precipitation now enters the sub-freezing surface layer and becomes super-cooled rain (raindrops below 0°C) which then freezes as it falls onto objects on the ground. If the warm layer is not deep enough to melt all the snow flakes into raindrops, partially melted snowflakes will refreeze in the subfreezing layer before reaching the ground, creating ice pellets. Because of the different sizes of snowflakes initially produced high in the cloud, a mixture of ice pellets and freezing rain often occurs when a warm layer of air in present in a winter storm.</p><p>The thicknesses and temperatures of these warm and cold layers above the ground constantly change during a storm, making the exact timing and amount of each precipitation type very difficult to forecast.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">11. Why are all snow flakes six sided?</a> <div class="expandContent pane"><p>The water molecule is the key here. The water molecule is made up of two atoms of hydrogen and one atom of oxygen and if you could look at it, you would see that they hold the shape of a triangle. As an ice crystal begins to form, water molecules arrange themselves in a way that forms a hexagonal lattice. This six-sided structure is reflected in the larger ice crystals and snowflakes that we see. While snowflakes can take on many different shapes and are often irregular in appearance, their formation is based on this six-sided structure.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. Can it ever be too cold for it to snow?</a> <div class="expandContent pane"><p>When the air temperature gets well below -30°C, there is very little water vapour available to produce significant snow. Ice crystals do form at very cold temperatures below -40°C so technically it can’t be too cold to snow. However, practically speaking, no significant snow will occur at these temperatures.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">13. Why does it snow at all when it's above zero degrees?</a> <div class="expandContent pane"><p>Snow falls when temperatures are above zero degrees because much colder air is located aloft in the clouds where the snow is produced. The shallow layer of air near the ground may be above zero but this layer is usually only a few hundred metres thick. The snow that falls into this above freezing layer does not have time to melt completely before reaching the ground. Generally, snow will not accumulate if the air temperature at the surface is above freezing. However, if snow is falling heavily enough, it is possible for the snow to accumulate, even though the air temperature is slightly above freezing.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="el-nio">El Niño<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. What are El Niño and La Niña?</a> <div class="expandContent pane"><p>El Niño and La Niña are phases of the climate cycle called the El Niño/Southern Oscillation which describes the ocean and atmospheric patterns occurring in and over the equatorial Pacific Ocean. El Niño is characterized by warmer than normal sea-surface temperatures west of South America that endure for several seasons, whereas La Niña represents the opposite, cooler phase. Changes in water temperature across vast stretches of the Pacific Ocean cause disruptions in the tradewinds and weather conditions. Both phenomena have a large impact on the jet stream and weather patterns around the world that can result in floods or droughts. El Niño events vary in intensity and recur every two to seven years. The term El Niño (“the boy-child”) was originally used to describe a local ocean current which occurred around December off the coast of Peru and Ecuador, but was later applied to a periodic warming of these coastal waters which affected the local ecology. While these meanings are still used today, the term El Niño has become more commonly associated with the larger periodic warming of the central and eastern Pacific waters and the corresponding changes in global weather patterns.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. How do El Niño and La Niña affect our weather?</a> <div class="expandContent pane"><p>The periodic changes in the Pacific Ocean water temperatures that define El Niño and La Niña can impact weather patterns around the world. The effects are more prominent in countries surrounding the Pacific Ocean and are most noticeable in the winter and summer months. During El Niño episodes, drier-than-normal conditions can affect much of South Asia and Australia while wetter and warmer-than-normal conditions occur across southern and western South America. During La Niña episodes, wetter-than-normal conditions can last for many months across South Asia and Australia while cooler-than-normal weather prevails in parts of South America.</p><p>In Canada, El Niño's impacts are most clearly noticed during winter in western Canada. While the southern United States sees cooler and wetter conditions, western Canada often experiences mild winters during an El Niño episode. Depending on the strength of the El Niño, milder-than-normal conditions may extend through Ontario, Quebec and towards Atlantic Canada. The opposite is true for La Niña episodes where colder-than-normal winter temperatures with heavier precipitation is seen, especially across western Canada.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. Is it possible to get a forecast for El Niño for next winter?</a> <div class="expandContent pane"><p>El Niño is a cyclical event that occurs every two to seven years lasting five to 18 months. Generally, El Niño conditions can be predicted with some success three to six months in advance. However, the strength of an El Niño or La Niña event is difficult to predict more than a few months in advance.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4.

Is El Niño getting blamed for weather it does not affect?

El Niño episodes can influence the jet stream pattern which may result in a warmer than normal winter across the Great Lakes, for example, but the exact impact depends on the intensity of the episode, and other circulations in the atmosphere. While El Niño and La Niña do affect global weather patterns, these phenomena do not directly cause individual storm systems which are the result of smaller circulations within the global jet stream pattern.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="clouds">Clouds<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. What are the types of clouds and how are they formed?</a> <div class="expandContent pane"><p>The visual appearance of clouds is defined in four primary groups:</p><p><strong>Cirrus:</strong> High clouds made of tiny ice crystals. They look like fine, wispy white strands of hair. Stratus: Layered, generally flat clouds. Stratus clouds can occur at various altitudes and can be thin or thick. <br/><strong>Cumulus:</strong> Distinguished from stratus clouds by the fact that they are not flat and have a heaping appearance. Smaller cumulus clouds look like white cotton balls and are made up of billions of tiny water droplets. <br/><strong>Nimbus:</strong> Clouds that are accompanied by rain.</p><p>Clouds are further classified according to the height of the cloud base:</p><p><strong>High-level clouds:</strong> The prefix "cirr" is used to describe high clouds. The primary types include cirrus, cirrostratus and cirrocumulus. <br/><strong>Mid-level clouds:</strong> The prefix "alto" is used to describe mid-level clouds. The primary types include altostratus and altocumulus. <br/><strong>Low-level clouds:</strong> Examples of low-level clouds include stratus, stratocumulus and nimbostratus. <br/><strong>Vertically developed clouds:</strong> These are clouds which generally have low cloud bases, but also have significant vertical height relative to their width. Examples are cumulus, towering cumulus, and cumulonimbus.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. Why don't clouds fall from the sky?</a> <div class="expandContent pane"><p>Those puffy, fluffy fair-weather clouds, known as cumulus clouds, are heavier than you might think. Take a single cloud about 1 km wide and 1 km long, and about as high as it is wide. Weigh all the cloud's liquid water, and you'll find it is weighs about 500 tonnes - more than a 747 jetliner fully loaded with passengers and fuel.</p><p>Because clouds are composed of light, tiny droplets - you'd need to collect more than 2 billion droplets to make a teaspoon of water - it doesn't take a lot to hold them up.</p><p>Clouds are suspended in the air by the lifting action of air currents (winds deflected from hills and mountains) but especially by convection, warm air rising from the surface of the earth. When the sun sets, these rising air currents quickly lose their heat source and constant force. Cumulus clouds in particular begin to descend as air currents cool, yet instead of descending all the way to the ground, the air in the clouds actually warms and starts to become drier, causing the droplets to evaporate. The clouds literally disappear before they reach the ground.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. How do holes form in clouds?</a> <div class="expandContent pane"><p>Sometimes invisible falling streaks of ice crystals from higher clouds are intercepted by thin, lower cloud composed of water droplets. The water droplets evaporate as the ice crystals grow in the saturated air within the cloud. The ice crystals then fall from the cloud and leave an almost perfectly circular hole. Evidence also strongly supports the suggestion that passing aircraft punch holes in thin clouds. Airplane exhaust produces ice particles, and in time, these ice crystals become large enough to fall out and eventually evaporate. Also, engine heat and turbulence along the wing tips mixes moist and dry air causing clear holes.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. Under what conditions can we expect stratus clouds? Are these convective clouds?</a> <div class="expandContent pane"><p>All clouds form when the surrounding air temperature cools down to the dew point temperature for the air mass. When this happens, water droplets form and appear in the sky. We call this group of droplets in the sky a cloud. An example of this effect can be found near the earth's surface in the formation of fog when the air temperature near the ground is equal to the dew point. When fog lifts up off the ground but remains a few hundred metres above the surface, we call it a layer of stratus clouds. Stratus and fog are not convective clouds. Stratus commonly occurs over the Pacific or Atlantic coastal waters in the summer and over open bodies of water in the spring and fall. In general, there is less convection in winter except near warm bodies of water that may cause local convection to occur and bring on snow squalls.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. Why is it that in METARs (Aviation Routine Weather Reports), we often see a first layer of stratus fractus clouds and a second of stratocumulus clouds? Wouldn't cumulus fractus and stratocumulus be more appropriate?</a> <div class="expandContent pane"><p>METARs describe clouds, or the various layers of clouds from the ground up. Often near the surface, there are bits of stratus cloud floating around but not enough for a complete deck of stratus. This gives the first layer a broken appearance, hence the name stratus fractus. Above this fractured layer, we find the more convective layer of clouds. If this convective layer is in the lower atmosphere, we call it stratocumulus (SC). Cumulus fractus (CF) should be used to describe widely scattered cumulus clouds.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Why can clouds appear extremely dark when they are approaching yet lighten up when they are above us?</a> <div class="expandContent pane"><p>The colour that clouds appear to be has more to do with their type than their location. Clouds laden with abundant moisture, i.e. formed with many droplets, will tend to be relatively dark since water droplets in the cloud will absorb light passing through it. Clouds such as cirrus that we see as thin streaks high in the sky, or cirrocumulus, that we see as small, round white puffs, contain relatively little moisture. In fact, cirrus clouds are almost exclusively composed of ice crystals. Clouds such as altocumulus, also known as middle clouds, are composed mostly of water droplets that appear as grey, puffy masses. Another fact determining the appearance of clouds is their position relative to the viewer and the sun. When the sun is visible, an approaching thunderstorm may look especially dark because of the contrast between the bright foreground lit by the sun and the dark background where the storm is located. When the storm begins to obscure the sun, the storm cloud may not appear as dark because of the reduced contrast within the field of vision.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="weather-systems">Weather Systems<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. Are there more tornadoes these days?</a> <div class="expandContent pane"><p>This is a difficult question to answer because the number of official tornadoes each year is really just the number of tornadoes that we have record of due to sightings or damage. This number has increased. For example, there was three times the number of tornadoes in 1990, than in 1953. However, these numbers may not represent an actual increase in the number of tornadoes but may instead be due to a higher percentage of tornadoes being seen and reported.</p><p>Today, population density is more widespread than in the past, with police, highway crews, farmers, fishermen and weather volunteers paying much more attention to severe weather. The general public is more alert to the dangers of severe weather, especially tornadoes. Improved technology has also had an impact with many more eyewitness accounts by people armed with cameras and cellphones. Greater numbers are also reflected through better radar systems and weather satellites.</p><p>As our awareness of severe summer weather increases, the tornado count will likely increase as well – even though the number of actual tornadoes may not necessarily be increasing.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. What are cyclones?</a> <div class="expandContent pane"><p>For many years, the word cyclone was widely misunderstood to mean only a twister or tornado. “Cyclone” is actually a generic term that describes low pressure systems ranging in scale from tornadoes and tiny dust devils to monstrous hurricanes and typhoons. It comes from the Greek word, “kyklon,” meaning cycle, circle or coil.</p><p>All cyclones have winds which converge inward toward a centre of low pressure. Apart from that similarity, the family of cyclones includes many different types of low pressure systems with differences in where they form, size and effects. Even though the word is very loosely applied to any strong wind today, it is usually reserved for huge, intense tropical low-pressure systems including: high wind and heavy rain storms called hurricanes in the Eastern Pacific and the Atlantic; typhoons in the Western Pacific; and cyclones in the Arabian Sea and in the Indian Ocean around Australia.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. When and how often do hurricanes happen in Canada?</a> <div class="expandContent pane"><p>Hurricanes that develop in the tropics and move up the eastern United States coastline mainly affect Atlantic Canada. Usually by the time they get to Atlantic Canada, these systems have weakened into tropical storms or transitioned into “post-tropical” storms which take on features like fronts and a broad wind field similar to our typical mid-latitude low pressure systems. It is rare for hurricanes to maintain hurricane strength when they reach the Maritimes and Newfoundland but it does happen and the peak time is September and October. Canadian waters are typically affected by tropical cyclones every year, with hurricanes affecting Canadian waters every few years.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. What is the most popular hurricane name?</a> <div class="expandContent pane"><p>Different naming rules are used in different ocean areas. In the Atlantic Ocean, the practice of naming tropical storms using female names was started in 1953. Male names were first used in 1979. Today a United Nations weather committee rotates six separate lists with alternating female and male names in alphabetical order. They chose names that are common in French, English or Spanish, are easy to pronounce and have fewer than ten letters. Names of violent, very destructive storms such as Katrina and Juan are retired from the list. The names most often given to a tropical storm or hurricane over the years are Anna/Ana and Arlene.</p><p>Some other hurricane name facts:</p><ul><li>The first female name was Alice; first male hurricane was Bob. </li><li>The first female names retired were Carol and Hazel in 1954; the first male name retired was David in 1979.</li></ul></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. How are twisters formed?</a> <div class="expandContent pane"><p>Twisters or tornadoes are still one of the most elusive creatures of the atmosphere. Although our understanding of tornadoes has improved over the years, we still do not have a complete understanding of how they form.</p><p>Most tornadoes form in severe or intense thunderstorms. In these storms, warm moist air at the surface rises rapidly as it converges into the centre of the storm due to the presence of cold, dry air aloft which makes the atmosphere very unstable. The other main ingredient is wind shear, which is a change in wind speed and direction with height. As the air rises, the wind shear is tilted from the horizontal into the vertical which creates an area of rapidly spinning air. As air continues to converge into the storm centre and accelerate upward, this spin is stretched vertically while shrinking horizontally which causes the winds to rapidly increase, similar to what happens as an ice skater draws her arms in. The funnel cloud forms when the moisture in the rising air condenses. When the spinning funnel cloud reaches the surface it is called a tornado.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Why do some tornadoes form a “straight” funnel between the earth and the base of the cloud and some a more curvy “S-shaped” funnel?</a> <div class="expandContent pane"><p>Every tornado forms from a severe thunderstorm, and even though scientists do not have a complete understanding of how they form, videos and camera shots show us that most tornadoes have a similar lifecycle. A tornado starts as a small wedge-shaped funnel from the base of a severe thunderstorm and works its way down to the ground. Once it touches the ground and starts to draw in all kind of debris, the funnel becomes more visible, widens and looks like a “straight” vertical funnel. As it proceeds further into the life cycle, it begins to change its shape and “slithers” until it dissipates.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. What determines the diameter of the actual funnel, as some tornadoes seem narrow and some seem to have a massive funnel?</a> <div class="expandContent pane"><p>The massive wedge shaped tornadoes are formed in exceptionally strong thunderstorms.

What does it mean when the barometric pressure is rising or falling?</a> <div class="expandContent pane"><p>Rising barometric pressure generally indicates that an area of high pressure is approaching. Falling barometric pressure generally indicates that an area of low pressure is approaching.

What is the difference between a thundershower and a thunderstorm?</a> <div class="expandContent pane"><p>There is no difference. Meteorologists classify these storms as "thunderstorms" or "severe thunderstorms" and the classification of the severe thunderstorm varies from region to region, and from province to province. Some people use the term “thundershower” to describe a weak thunderstorm. Weak thunderstorms, however, can still cause damage.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle"> 10. What’s the difference between a snow squall and a blizzard?</a> <div class="expandContent pane"><p>There are a number of differences between a snow squall and a blizzard.

How can snow fall in Mexico when we have warm temperatures and no snow in Canada?</a> <div class="expandContent pane"><p>In winter, large undulations can develop in the jet stream, known as troughs and ridges. In a deep trough the jet stream dips far to the south before curving back towards the north. This can bring cold and snow to places like Texas and the mountainous regions of Mexico, despite their southern location. Often when there is a big dip in the jet stream, or trough, there will be a compensating area downstream where the jet stream bulges far to the north – forming a ridge. Areas under this ridge, such as the eastern Great Lakes, often experience warm temperatures with no snow despite being farther north.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. I heard that weather moves from west to east, such as from western Canada to eastern Canada (maybe 4-5 days later) and then another 4-5 days to England and France. Is this true?</a> <div class="expandContent pane"><p>Yes. Most of the time weather does move from west to east, with some variation. For example, sometimes our weather moves from the northwest to the southeast or from the American Southwest into the Canadian Northeast. The main reason for these variations is the position of the jet stream. On rare occasions, however, large “blocking” areas of high pressure aloft develop in the northern latitudes, particularly over the northern oceans such as the north Atlantic.

However, when meteorologists and climatologists refer to spring, they are often grouping together the three transition months that lie between the coldest and warmest months of the year. Using this criterion dictates that meteorological/climatological spring is actually defined to be March, April and May.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. Why does the North Pole have roughly six months of daylight and six months of darkness? Does the same apply to the South Pole?</a> <div class="expandContent pane"><p>The reason why the North Pole experiences four to six months of darkness in the winter and four to six months of daylight in the summer is because of the earth's tilt. The earth's vertical axis (the axis on which it spins) is tilted 23.5 degrees. At the same time, the earth also revolves around the sun. It is this combination of tilt and orbit that gives the total darkness or daylight.</p><p>When the earth travels around the sun, its tilt causes the North Pole to either point away from the sun (as in winter) or towards the sun (as in summer). When the North Pole is pointed towards the sun in the summer, it is exposed to constant sunlight for a period of months. When the North Pole is pointed away from the sun in the winter there is total darkness. The same goes for the South Pole.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. What is the "ideal" range of humidity for the inside of the house during the winter months?</a> <div class="expandContent pane"><p>Typically during the winter months the relative humidity in a home runs at around 15%. This is too low because it causes your skin to chap and your throat to feel dry. It is suggested that the relative humidity in your home should be kept between 35% to 45%. By keeping the humidity up in your home, you won't need to have the thermostat set as high because less moisture will be evaporating from your skin, causing you to feel more comfortable.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. What is a "normal" temperature?</a> <div class="expandContent pane"><p>A normal of temperature, precipitation or any other weather element is the average of the observed values of that element over a period of time. The period of time depends on how long the particular weather station has been in service. The word "normal" can be misleading because values other than the "normal" are not unusual.</p><p>By international agreement, averages or normals cover a 30-year period from the beginning of one decade to the end of the third, e.g., from 1971 to 2000. For example, to calculate the normal daytime high temperature for Winnipeg on September 15, add together the daily high temperatures on this day for the 30 years from 1971 to 2000 and divide the total by 30. This quotient is the average or normal daytime high temperature for September 15 from 1971 to 2000 inclusive.

If "normal" temperatures are calculated as a 30-year average, how is it possible to have jumps between daily normals?</a> <div class="expandContent pane"><p>In Canada, we calculate the daily normal high using the recorded daily high for the past 30 years. The high of the day before or the day after is not considered in the calculation. Through this averaging, extreme values will be included in the data set. Therefore, a day to day variation in the "normal" temperatures will occur.</p><p>In the United States, the climatic normals are calculated differently. The high temperatures for each month are run through a statistical algorithm and the extremes are removed. After the variations are removed, the 30-year normal values are calculated.

Has it ever snowed in Los Angeles, or in any of California’s major cities?</a> <div class="expandContent pane"><p>In downtown Los Angeles, snowflakes have been observed on over 20 occasions in the past 100 years. However, on January 15, 1932 more than 5 cm of snow fell during the morning in the downtown, the most ever recorded on one day in Los Angeles. Even the beaches at Santa Monica were white with snow. San Diego received a centimetre of snow that remained on the ground for a little more than an hour. San Francisco's most memorable snowfall came on February 5, 1887 when snowfall blanketed the city with 10 cm. In these areas, snow is most likely to fall along the coast when a strong northeasterly flow of cold air descends from the mountains.</p><p>The snowiest place in North America is the Cascade Mountain range in Washington State where over 1500 cm of snow falls on average every year.

Why is it that on the East Coast they get hit with heavy snow and cold and the West Coast gets warmer weather in the winter when they appear to both be on the same latitude line and near the ocean?</a> <div class="expandContent pane"><p>The prevailing winds in the mid-latitudes of the Northern Hemisphere are generally westerly. This pushes air masses and weather systems from west to east across Canada. For eastern Canada, this means cold air masses travel eastward over the continent and occasionally meet with moisture-laden low pressure systems from the south. On the west coast, the flow is usually off the warm Pacific Ocean. The ocean keeps the air masses relatively mild.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. Why is the weather in North America, e.g., Ohio, colder than the weather in London, England, even though England is further north from the equator?</a> <div class="expandContent pane"><p>The prevailing westerly winds in the mid-latitudes of the Northern Hemisphere are responsible for this difference. Weather systems in England generally come from the Atlantic Ocean which helps to moderate the temperature. On the other hand, the interior of North America is subject to both mild air masses from the Pacific and outbreaks of arctic air which can come directly from the polar regions without being moderated by water.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">8. There is lake-effect snow near the Great Lakes, but what about smaller lakes?</a> <div class="expandContent pane"><p>There are several conditions required to form lake-effect snow. The most important one is sufficiently cold air moving across a large body of water. For example, the size of Shuswap Lake around Salmon Arm, B.C., is too small for winds to pick up enough moisture to produce significant lake-effect snow like what occurs downwind of the Great Lakes. However, under the right conditions, even small lakes like Lake Simcoe in Ontario can provide enough moisture to produce flurries.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9. Why is Ottawa colder and snowier than Toronto?</a> <div class="expandContent pane"><p>The Great Lakes, and specifically Lake Ontario, help to keep Toronto warmer than Ottawa during the winter months. Ottawa has a lower average temperature which allows for greater snowfall as more of the total precipitation falls as snow rather than rain. Ottawa also experiences more total precipitation during the winter because of its closer proximity to large nor’easter storm systems which develop along the eastern seaboard of North America.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">10. Why do areas like Mansfield, Ontario, not receive the snowstorms that towns five and ten minutes west and north of it receive?</a> <div class="expandContent pane"><p>It is difficult to generalize the statement and say that any one location is significantly warmer, colder or receives less precipitation than a nearby location without looking at recorded meteorological information. For comparisons, local weather stations must be close enough together to detect differences between locations that are geographically close.</p><p>Meteorologists often use the term ‘local effects’ to describe large differences in weather over relatively small areas.

From which direction do winter storms generally come from in the city of Ottawa? Has there been a change in the severity of storms in the Ottawa region?</a> <div class="expandContent pane"><p>In general, weather systems move from west to east in Canada, and most winter storms moving in to Ottawa come in from the west. There can be variations in this direction. Some weather systems may move in from the southwest, and some from the northwest. Generally, the storms with the heaviest precipitation tend to come from the southwest because they draw on warmer air with more available moisture. In general, the "average severity" of storms in this area has not changed significantly over the past few decades. Of course, some winter storms leave more snow than others and records of all kinds are occasionally set, but there has been no significant trend observed in storm severity.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. Why is it that southwestern British Columbia never gets caught in a deep freeze or a cold snap the way the Prairies do in the winter?</a> <div class="expandContent pane"><p>Coastal British Columbia rarely experiences a deep freeze for long periods of time because the average wind flow for B.C. during the winter is from the west. This wind direction provides a mild flow of Pacific Ocean air over British Columbia. However, even coastal B.C. can occasionally experience cold temperatures when an arctic high pressure system pumps cold air through the interior valleys and out to the coast. In these cases, the wind blows from land and subfreezing conditions can occur across the Lower Mainland. However, these episodes of cold air rarely last for longer than ten days as the westerly flow from the Pacific eventually returns.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">13. Vancouver, British Columbia once had a cyclone about fifty years ago. Can we expect any high winds - ever - like are seen in Florida? Is it true that hurricanes happen on the east coast and cyclones on the west coast?</a> <div class="expandContent pane"><p>The coast of British Columbia experiences very strong low-pressure systems that can bring hurricane force winds (greater than 120 km/h). However, because of cool Pacific Ocean waters, the west coast of Canada does not experience tropical cyclones so it is impossible to achieve the extremely high wind speeds generated by a major hurricane. Occasionally, the remnants of a typhoon can cross the Pacific and affect the west coast as an unusually powerful low pressure system. Hurricanes do occur along the west coast of North America, along the Mexican coast where water temperatures are warm enough to support tropical cyclones.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">14. Why is it often very windy in the Prairies?</a> <div class="expandContent pane"><p>The main reason is topography. The Prairies’ flat terrain allows air to blow across the region without any obstacles like mountains, forests, valleys or hills.

Why do weather patterns in the U.S.A. usually travel from west to east?</a> <div class="expandContent pane"><p>Weather patterns in the U.S.A.

Where in Canada are thunderstorms more likely to be and what makes these areas different from others that don't get as many thunderstorms?</a> <div class="expandContent pane"><p>Two areas of Canada experience significantly more thunderstorm activity than the rest of the country: Southern Ontario and the foothills of Alberta followed closely by southern Manitoba and Saskatchewan. For a thunderstorm to occur, instability is required. Instability occurs when warm humid air at the surface lies beneath cooler, drier air higher in the atmosphere. Southern Ontario receives its warm humid air from the Gulf of Mexico. Thunderstorms most often occur here in the summertime when southwest winds bring the humid air mass into the region.</p><p>In contrast, westerly winds in the upper atmosphere ensure cool dry air is aloft over Alberta. This creates the necessary instability for thunderstorms to form. Additionally, the foothills act as a trigger for thunderstorm development as air is forced to rise in their vicinity. The southern Prairies, especially southeast Saskatchewan and southern Manitoba, are a close second for thunderstorm activity as warm humid air from the U.S. fuels thunderstorm development.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">19. In Ottawa, as soon as November 1 comes around every year, there are soft grey clouds that hang over the city for the whole month. Is there a lot less sun this time of year and what would cause these grey clouds to linger day after day?</a> <div class="expandContent pane"><p>The hours of bright sunshine are low during November as the air continues to cool and the relative humidity increases. Low clouds can be stubborn to clear since heating from the sun is insufficient to mix the air and dissipate the clouds.

Why are there no hurricanes in California?</a> <div class="expandContent pane"><p>The eastern North Pacific Ocean off Mexico and Central America is the second most active hurricane alley with nearly one quarter of the world's tropical storms. In a typical year, 17 tropical storms form there, compared to nine or ten in the Atlantic and Caribbean.</p><p>Despite all this storm activity, hurricanes rarely make it to the California coast for two reasons:</p><ul><li><strong>Tropical cyclones moving out of the tropics tend to move toward the west-northwest.</strong> In the Atlantic, this direction often brings storms toward the United States. In the Eastern Pacific, a west-northwest track takes hurricanes away from the California coast. </li><li><strong>Water temperature:</strong> Along the Atlantic coast, the Gulf Stream provides deep warm water above 27°C to fuel hurricanes.

Why do space flights get cancelled because of weather when they fly above any weather systems?</a> <div class="expandContent pane"><p>Space shuttles are more vulnerable to weather than an ordinary airplane. A simple thunderstorm, a few drops of rain, some clouds, or strong winds can delay or cancel a shuttle launch. This is because of the fragile components used on the space shuttle.</p><p>When it is time to fuel the main engines, the combination of humidity and temperature can create ice on the tanks. Chunks of ice could fly off and damage the shuttles' insulating tiles at blastoff. Rain could soak the tiles. Later they could freeze in space and crack. Surface winds, above 45 km/h, could blow the shuttle into the access tower during liftoff.</p><p>Cape Canaveral is located in one of the most active thunderstorm regions in the world, with an average of 100 thunderstorms a year. On November 14, 1969, lightning struck Apollo 12 half a minute after liftoff.

How is the water content of snow measured?</a> <div class="expandContent pane"><p>As a very general rule, the depth of freshly fallen snow is converted to its water equivalent by dividing that depth by 10. However, the water content of snow varies greatly , depending on the temperature, wind speed and moisture content of the air through which the snow falls. Very wet snow falling in air near freezing may have a water equivalent of 6:1, meaning 6 cm of snow = 1 cm of water. On the other hand, with dry and powdery snow the ratio may be as high as 30:1. The only sure way to measure the water content of fresh snow is to melt it. The standard instrument to measure water equivalent is the Nipher snow gauge. The snow in this receptacle is taken indoors until it completely melts. The contents are measured to get the true water content of snow since the last observation.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. How is snow measured?</a> <div class="expandContent pane"><p>Snowfall measurements just may be the least precise of all weather observations. In most countries, snowfall measurements are no more complicated than simply going out and sticking an ordinary ruler into the snow in several places and taking an average depth. Getting a measurement that is truly accurate, however, is rarely that easy. Finding a representative site can be a problem. The best place to take measurements is in an undisturbed, flat, open area away from overhangs. The standard snow ruler is one metre long and marked in centimetres by fifths. Anything less than 0.2 cm is noted as a trace. It is important to note that the following things happen to snow as it sits waiting to be measured:</p><ul><li>If it's warm, snow melts as it hits the ground </li><li>If it's windy, snow drifts or blows away </li><li>If it accumulates over 10 to 15 cm, snow settles and compacts under its own weight and evaporates</li></ul><p>Because of these fates, snow depth on the ground sometimes decreases even as snow continues to fall.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. Why kilopascals and not millibars?</a> <div class="expandContent pane"><p>In 1971, Parliament adopted the modern form of the metric system known as the International System of Units or SI. That same year, the international body responsible for maintaining standards of measurement decided to replace the "bar" as in millibars, with the Pascal as the SI unit of pressure. Millibar is metric but not SI metric. The SI metric system is founded on seven well-defined base units including the metre for length, kilogram for mass and second for time. A second group contains units that are derived directly from the base units. For example, pascals derive from kilograms, area in square metres and time in seconds. The derived unit of pressure, pascal (Pa), is named in honour of Blaise Pascal, a 17th century French physicist and writer. Most home barometers measure air pressure in inches or millimetres of mercury or in units called millibars. All official pressure readings, though, are expressed in kPa. If your barometer has units in inches, to convert to kilopascals multiply your barometer's readings by 3.386. For example, if your barometer is reading 29.91 inches, that's 101.31 kPa.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. What is the relationship between the various terms used in measuring atmospheric pressure: inches of mercury, kilopascals, millibars and inches. Why can't they be correlated in the reporting of weather conditions?</a> <div class="expandContent pane"><p>All the above relationships are just a different way of measuring a height of mercury column in a mercury barometer. Different measurements show equivalents in different measurement systems: Imperial (inches of mercury, pounds per square foot), metric (millimetres of mercury) and International Scientific (SI) units (millibars, kilopascal).</p><p><strong>1013 millibars = 101.3 kilopascals =29.92 inches of mercury.</strong></p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle"> 5. How do you set a barometer? </a> <div class="expandContent pane"><p>A barometer is usually corrected to sea- level pressure. This is done by knowing that, on average, atmospheric pressure decreases by about 1 kilopascal (kPa) for every 100 metreers’ increase in elevation. To convert from station pressure to sea level pressure, add 1 kPa for every 100 m that the station is located above sea level. For example, if the station pressure at Ottawa International Airport (elevation 114 m above sea level) is 100.05 kPa, add 1.14 kPa to find the sea- level pressure. The sea level pressure would be 101.19 kPa.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Is the air pressure shown in the local forecasts a corrected figure or uncorrected? How do you convert one to the other?</a> <div class="expandContent pane"><p>The pressure on thein local forecasts is corrected to reflect the sea- level pressure. It's a little complicated. If you have a barometer at home, you will notice your barometer will actually read at a lower pressure than what you will see on the television screen.</p><p>Take Vancouver and Calgary for example. Vancouver is about 3 metres above sea level and Calgary is about 1000 metres above sea level. The pressure in Calgary is lower than it would be in Vancouver because the weight of the air above any given place in Calgary is less.</p><p>Here's how you convert air pressure:</p><p>P (sea level) = P (observed) + [{(1kPa/100m) x height above sea level]}. For example, if observed pressure is 90 kPa in Calgary, its pressure at sea level is as follows:</p><p>P (sea level) = 90 + (1000/100) <br/> P (sea level) = 90 + 10 = 100 kPa.</p><p>Why make the conversion?

For example, heat transfer or radiation may affect a thermometer that is attached to the side of a house. If possible, place your thermometer away from any heat sources (buildings, houses, parking areas and streets) and away from direct sunlight.</p><p><strong>2)</strong>Indoor thermometers follow the same basic rules.

The other type is a little larger with a 120 square centimetre opening, and it's called a tipping rain gauge. 30 mm of rain on these types of rain gauges does not sound as impressive as over a larger area, for example, a square kilometre with 30 mm of rain equals many thousands of tonnes of water.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9. I would like to know how the cloud ceiling is measured. For example, if the ceiling is 2,000 feet, how was that determined?</a> <div class="expandContent pane"><p>Cloud ceilings are measured with an instrument called a Laser Ceilometer. This large oil- drum- shaped instrument has a laser inside that fires a laser beam up into the sky. As the laser hits the cloud ceiling, it bounces back to the instrument. The time difference between the laser firing and the laser light bouncing back is what we use to calculate the height of the cloud ceiling.</p><p>Previously, we used small weather balloons. The weather balloon would be released and we would watch it until it disappeared into the clouds while timing how long it took for the balloon to disappear.

How is the dew point temperature measured?</a> <div class="expandContent pane"><p>The dew point temperature can be measured with a device called a wet-dry bulb thermometer. A wet-dry bulb thermometer is basically two thermometers placed side by side. The bulb of one is covered by a wick that is always kept wet (wet bulb) and the other is left alone (dry bulb). Just like water evaporating from a person's body right after they come out of the shower, the thermometer with the wet wick will cool as the water evaporates from the wick. The less water vapour in the air or the drier the more water will evaporate from the wet wick. The more water evaporates, the cooler the reading on the wet bulb thermometer. The dry bulb, or regular thermometer, is used as a reference to give the current air temperature. The temperature difference between the two thermometers tells us how much moisture is in the air:- the greater the difference, the drier the air.</p><p>For example, a dry bulb temperature of 22°C and a wet bulb temperature of 10°C result in a difference of 12 C°. In this case, the air would be considered fairly dry. A dry bulb temperature of 22°C and a wet bulb temperature of 20°C results in a difference of only 2 °C. In this case, the air would be considered moist.</p><p>Electronic hygrometers are used in most modern weather stations equipment to measure the dew point temperature.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">11.

If the temperature reached the dew point and it was still below, what happens?</a> <div class="expandContent pane"><p>The purpose of having a dew point in the winter is the same as it is in the summer. We want to see how much moisture is in the air, even in the winter. If the spread between the dew point and the temperature is small, then the air is moist; if the spread is large, the air is dry.

Why does the weather change?</a> <div class="expandContent pane"><p>The sun heats different parts of the earth at different rates. Without weather, the warm areas would keep getting warmer and the cold areas would keep getting colder. Weather and weather changes are nature’s way of taking care of this imbalance. For example, when a sunny stretch of weather is broken up by a rainy day brought on by low pressure, that low pressure system was necessary to transport warm air northward toward the cold polar regions and cold air southward toward the warm tropical regions.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">13.

What causes steam to rise from a wet asphalt surface?</a> <div class="expandContent pane"><p>Sometimes you can see steam rising from asphalt surfaces when the sun comes out after a rain or a snowfall. The asphalt absorbs the sun's heat and causes the top layers of the asphalt to warm. This in turn warms the moist air in close contact with the road surface. As the rising air currents of warm, moist air above the asphalt encounter the cooler surrounding air, some of the water vapour condenses into tiny droplets that we see as wispy streamers that resemble smoke.

Is a "whiteout" when a blizzard obscures visibility?</a> <div class="expandContent pane"><p>True "whiteouts" occur mostly in the Arctic and Antarctic during the day when light is bounced in all directions between a uniformly overcast sky and snow or ice on the ground. Clean snow and ice reflects nearly 85% of incoming light. Falling snowflakes, suspended fog droplets, or ice particles in the air can add to this reflection. In a true whiteout, neither shadows, nearby objects, landmarks, nor clouds are discernable. All sense of direction, depth perception, and even balance may be lost. Land and sky seem to blend, and the horizon disappears into a white nothingness. Whiteouts cause confusion, tricking pilots into believing down is up and travellers into thinking far is near. Of course, we often refer to "whiteout conditions" when referring to blowing snow within snow squalls, winter storms and blizzards that can reduce visibility to near zero. In these cases, all sense of direction and depth perception can be lost as a result of blowing snow making everything appear white to the observer and creating very dangerous conditions for travel.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. When can we expect Chinook winds?</a> <div class="expandContent pane"><p>Chinook winds are the result of moist weather patterns, originating off the Pacific coast, cooling as they climb the western slopes, and then rapidly warming as they drop down the eastern side of the mountains. A Chinook usually begins with a sudden change in wind direction towards the west or southwest, and a rapid increase in wind speed. They generally occur from the fall through spring.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. Why do I never hear thunder during the winter?</a> <div class="expandContent pane"><p>The development of thunderstorms depends largely on how quickly the temperature decreases as you go up in atmosphere. Because surface temperatures in the summer are much warmer than in the winter, there is usually a greater difference in temperatures at the surface than higher in the atmosphere in the summer. When this similar vertical temperature profile develops in the winter, thunderstorms can develop.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Why does the sky on the horizon turn red or pink in the evenings?</a> <div class="expandContent pane"><p>As the sun begins to set at the end of the day, the sun's rays which reach our eyes must pass through a thicker layer of the atmosphere than when sun is directly overhead. When this happens, molecules in the earth's atmosphere absorb more of the radiation, but it gets absorbed preferentially. The shorter light waves of the visible light spectrum, the greens and blues, get absorbed, while the longer red rays are able to penetrate. Therefore, red is the colour we see. Dust and smoke particles can help to enhance the scattering of sunlight creating even more vivid red skies at dusk.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. Why is the sky blue?</a> <div class="expandContent pane"><p>White light is composed of a spectrum of colours. Molecules of oxygen and nitrogen gas in the atmosphere scatter light, but not all sunlight is scattered equally. It turns out shorter wavelengths of light, such as violet, blue and green, are scattered more by these molecules than longer wavelengths of light such as yellow, orange and red. As a result of this preferential scattering of the short wavelengths of visible light, the sky appears blue.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">8. Why the jet stream usually shown as extending throughout all of North America on weather maps, even though most of the time no fronts are depicted in the area?</a> <div class="expandContent pane"><p>In weather forecasting, the jet stream is one of the principalle features we use to describe the overall weather pattern. When we talk about the jet stream, we are generally describing the zone of fastest- moving winds in the upper part of the troposphere (the layer of the atmosphere where weather occurs) which define the path storm systems travel and reflect the general division between warm and cold air. The height of the jet stream varies depending on the season and weather pattern, with an altitude of 10 km being a rough guideline for the altitude of the jet stream over Canada.</p><p>While the jet stream is typically drawn as one curvy line on a weather map, there can actually be multiple segments of strong upper level winds and even significant breaks where upper level winds are weak. For presentation purposes, the jet stream drawn on weather maps is a simplified version of the often complex structure of the upper level wind fields.</p><p>Meteorologists also talk about low-level jets where are separate phenomena. These low-level jets exist within the first couple kilometers of the troposphere, sometimes ahead of strong cold fronts. Like upper-level jets, these low-level jets are the result of differences in temperature and pressure, but they occur on a much smaller scale as part of individual weather systems.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9. We always see the jet stream for North America. What does it look like for the other side of the world, i.e. Europe or Asia?— Is there a jet stream in the southern hemisphere?</a> <div class="expandContent pane"><p>Yes. The shape of the jet stream can be thought of as a long, constantly undulating skipping rope which extends around the mid-latitudes of the world. In the northern hemisphere, the jet stream extends across North America, over the Atlantic, through Europe and Asia, and back across the Pacific in a series of ups and downs which meteorologists call ridges and troughs. A similar pattern exists around the mid-latitudes of the southern hemisphere. In both cases, air generally moves from west to east within the jet stream flow, but dips north and south at times depending on the specific weather pattern. It is the constant movement of these ridges (fair, generally warm weather) and troughs (cool, generally unsettled weather) which causes the variation in our weather.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">10. What are/is the best times and ideal viewing conditions for the northern lights?</a> <div class="expandContent pane"><p>The northern lights, also called aurora borealis, are a result of the solar wind (energetic particles from the sun) interacting with nitrogen and oxygen atoms in the earth’s upper atmosphere, generally above 80 km altitude. The earth’s magnetic field concentrates this interaction in a ring around the north and south magnetic poles. In Canada, this means the northern lights are most likely to be seen in a belt close to 60 degrees north latitude. Many winter nights are clear and free of haze and that is why winter is often suggested at the best viewing time, although there is a tendency for the most auroral activity to occur around the equinoxes.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">11. What is the odd blue ring around the moon at night?</a> <div class="expandContent pane"><p>The bluish ring around the moon at night is caused by ice crystals high up in the atmosphere (about 7 km or 22,000 feet above the surface) which refract the moonlight in such a way that they create a halo. The effect is much like that which occurs when sunlight passes through an area of rain and creates a rainbow, or when a light passes through a prism and is split into the colours of the spectrum.</p><p>The bluish ring is caused by ice crystals high up in the atmosphere (around 7 km above the ground) which refract the moonlight in such a way that they create a halo. A halo sometimes precedes the onset of unsettled weather within the next 24 hours. This is because the ice crystals are part of cirrus clouds, which are those thin, high clouds that often run ahead of an approaching storm system.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. What does a cross, similar to rings around the moon, mean?</a> <div class="expandContent pane"><p>It is probably caused by parts of a halo breaking up. Halos are produced by the refraction of light through ice crystals. A solid deck of high cirrostratus clouds is necessary to obtain a complete halo. If there are breaks, you will see some arcs of the halo. Chances are that when you looked up, there happened to be some breaks at just the right spot for you to see a cross. A halo indicates a possible weather change because high clouds are usually the first to make an appearance from approaching storms.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">13. Does lightning come down from the sky or up from the ground to the sky?</a> <div class="expandContent pane"><p>Lightning actually does both.</p><p>In the typical downward lightning case, an invisible stream of ionized air from the cloud, called a stepped leader, travels downward following a jagged path and will try to combine with a ground streamer going upwards towards the cloud. Generally, there are a few of these upward streamers, and when the first one connects with the main downward stepped leader, there is a massive release of energy called the return stroke. It is this return stroke that we see in the form of the lightning flash and hear it in the form of thunder. All of this happens so quickly that our eyes are only able to see the high energy return stroke. Rarer, is the occurrence of upward lightning that is initiated by tall buildings. These cases work in ways similar to downward lightning except the stepped leader is initiated by the top of a tall building or tower which carries a significant charge relative to the cloud above. If the stepped leader connects with an area of opposite charge in the cloud, upward lightning occurs.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">14. What causes sheet lightning as opposed to fork lightning?</a> <div class="expandContent pane"><p>Lightning is the result of a massive discharge of energy within clouds or between a cloud and the ground. When this discharge (or giant spark) occurs between the cloud and the ground, we refer to this as cloud-to-ground lightning. Some people call this fork lightning when the lightning channel has multiple points of contact to the ground. When a lightning discharge occurs within a cloud, the light is reflected off the water droplets within a cloud causing a diffusion of the light. At night, this diffusion of light from the original lightning channel causes the whole cloud or much of the sky to light up, creating the effect of a sheet of lightning.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">15. How do we predict tides and their height?</a> <div class="expandContent pane"><p>Tides are caused by the influence of the moon and sun on the earth's surface in combination with the rotation of the earth. The moon accounts for the majority of the tidal effect with the sun playing a secondary role. The tidal cycle consists of approximately two high tides and two low tides in a day. For example, there is approximately 12.5 hours between high tides. This means that about 6.25 hours after a high tide, there is a low tide.</p><p>The moon's distance from the earth is one factor that affects the tides. The tides are highest and lowest (have their greatest range) when the moon is nearest the earth in its orbit. The tides have their smallest range when the moon is farthest from the earth in its orbit.</p><p>The phases of the moon also have an influence on tides. The tides are highest and lowest when the moon is new or full. At this time, the moon, sun, and earth are aligned and the sun and moon experience their strongest gravitational attraction towards the earth. These tides are called Spring tides although they have nothing to do with the season. The tides have their lowest range when the moon is in first or last quarter. This is because at these phases, the sun, moon, and earth form a right angle and therefore the gravitational attraction is weakest. These tides are known as Neap tides.</p><p>Observations from tidal gauges are used to make accurate tidal predictions since the local bathymetry (shape and depth of the ocean bottom) has a great impact on the timing and height of the tide at any given location.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">16. What was the "Perfect Storm"?</a> <div class="expandContent pane"><p>The so- called “Perfect Storm” is also known as the Halloween Storm of 1991. This storm developed when an unusually strong trough in the jet stream moved off the east coast of the United States and absorbed the remnants of Hurricane Grace. The resulting storm produced strong winds and incredible waves throughout this part of the Atlantic Ocean, affecting large sea vessels and coastal communities.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">17. What is the difference between a cyclone and a hurricane?</a> <div class="expandContent pane"><p>The word “cyclone” is a generic term for a low- pressure system. Tropical cyclones (which include tropical storms and hurricanes) develop over tropical ocean regions and have no fronts associated with them. These systems have extremely strong winds very close to the centre of the storm. On the other hand, a mid-latitude cyclone, or typical area of low pressure, forms from the clash of warm and cold air masses that occur frequently at Canadian latitudes. These systems tend to have larger but weaker wind fields than tropical cyclones.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">18. What are “les suetes” winds?</a> <div class="expandContent pane"><p>On the western shores of Nova Scotia's Cape Breton Island, damaging local winds are known as Les Suetes, derived from the French for southeast: sud est. These strong southeasterlies occur in advance of a low pressure system as the air is funneled through gaps in the Cape Breton highlands. When the wind rushes down the side of the highlands, strong gusts develop which have been recorded in excess of 150 km.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="weather-lore">Weather Lore<span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1. What is "the calm before the storm"?</a> <div class="expandContent pane"><p>The period of time before severe weather affects an area is known as the "calm before the storm". When a thunderstorm approaches, it pulls in huge amounts of warm and moist air at the surface. The surface winds just ahead of the main rising updrafts within a storm are sometimes lulled into a temporary calm as the primary air motion is upward. The air above the surface continues to ascend and the updrafts well above the surface gain incredible speed – sometimes exceeding 100 km/h. Immediately behind these upward motions of wind, called updrafts, you will find heavy rain, hail, lightning and thunder. This causes powerful downward wind gusts, called downdrafts, to hit the ground. Strong gusty winds will occur as a result of the downdrafts. These effects mark the end of the "calm before the storm".</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">2. Dry cold versus damp cold?</a> <div class="expandContent pane"><p>The assumption that dry cold is better than damp cold is largely a myth. Soldiers exposed to severe cold in climate-controlled cold chambers did not find damp cold any more penetrating than dry cold and, if you consider the physics of heat transfer, the differences between the two are negligible. But why then do the majority of Canadians prefer dry cold to damp cold?</p><p>One's perception of comfort or discomfort while exposed to cold air depends on several factors but only consideration to weather conditions will be considered here. Cold, dry days usually have sunny skies, high pressure and light winds – weather that is much more psychologically pleasing than overcast skies and shivering wind chill. Therefore, there's good reason to believe that you'll be more comfortable in a dry cold than humid cold, but it's not because of the difference in humidity. All this assumes one is not perspiring, his or her clothes are dry and that it's not raining.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">3. What is good fishing weather?</a> <div class="expandContent pane"><p>The saying goes, "When the wind is from the east, the fish bite the least." In the Northern Hemisphere, stormy low-pressure systems rotate counterclockwise with the prevailing winds blowing from the east ahead of a storm. With the approach of such storms, fish head to the bottom of the lake or stream, where they are less active and refuse to bite. Anglers love to argue over which weather makes fish bite more or less. It’s believed that:</p><ul><li>Fish hide on sunny days or when it thunders. </li><li>A slight ripple of the water leads to better fishing.</li></ul><p>Good fishing occurs with rising pressure, yet it’s said that fish start biting when the barometer starts to fall. There may be a grain of truth to some of these superstitions. Generally, fishermen are some of the best at reading the signs of weather, hoping it will improve their chances. In the end, anglers probably still have no idea why they catch their limit one day and nary a nibble the next.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">4. When leaves show their undersides, is it a sign of rain?</a> <div class="expandContent pane"><p>Plants and trees respond in a variety of ways to changes in the weather. It has been said that before rain, the leaves of trees curl up and show a great deal of their under surfaces. Here is a possible explanation. Ahead of a local shower or thunderstorm, the air is moister. The damp air softens the leaf stalks and allows them to be more easily lifted by the breeze. This, coupled with the rising currents of heated air ahead of the precipitation, exposes the under-sides of leaves. However, windy conditions in general will cause leaves to show their undersides and there are many cases where windy weather does not bring rain.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">5. Is it colder during a full moon?</a> <div class="expandContent pane"><p>A full moon on its own does not contribute significantly to temperature. However, overnight temperatures are often colder with a full moon because there are few or no clouds to trap and hold in the day's warmth (like how a blanket works). When the sky is clear after sunset, the day's heat radiates to space, chilling the air near the surface.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">6. Can you tell the weather from smoke signals around a chimney?</a> <div class="expandContent pane"><p>Weather lore says that when chimney smoke sinks upon the roof and falls to the ground, it signals rain or snow within 24 hours. In such situations, the dirty particulates in smoke absorb the added moisture in advance of the storm. This makes the smoke heavier and is dragged down to the roof. Conversely, in dry, calm weather, a column of hot smoke from a chimney rises straight and will continue to rise as long as it is warmer than the surrounding air. Under persistent high pressure, the air near the ground is usually dry and cool, encouraging a rising plume. Smoke that rises vertically often foretells good weather. However these are only general rules and modern weather forecasting is much more accurate at predicting precipitation than using smoke signals around a chimney.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">7. Can you predict weather by sound?</a> <div class="expandContent pane"><p>To a certain degree, this seems to be true. We seem to hear distant sounds such as train whistles and ringing church bells better before a storm approaches.</p><p>When the sky is overcast and humid (often the conditions that exist before a thunderstorm), sound can travel farther because rising and lowering air currents and strong gusty winds that rapidly break up sounds are weaker. During fair weather, these movements are present and therefore do not allow sound to travel as far.</p><p>There's even a piece of weather lore that supports this notion:</p><p><em>Sound travelling far and wide A stormy day will betide.</em></p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">8. Why does the wind make more noise in the winter than in the summer?</a> <div class="expandContent pane"><p>On average, the wind is 25% stronger in the winter than in summer because of stronger areas of low and high pressure. Part of the reason may simply be that in winter, winds whistle through gaps and cracks around closed doors, windows and open chimneys.</p><p>Also, winter sounds are generally much easier to hear because there are fewer competing noises like voices and sounds from birds and insects. Further, wind sounds are more audible as they rustle dry leaves. Actually, the wind can create a whole symphony of noises, including humming telephone wires and whispering pine needles. As the wind rushes by a wire, bare twigs and even the branches of trees, the air becomes unstable and forms tiny whirls or ripples. These vibrations have a pitch that varies directly as the speed of the wind. It is also well known that the humming of telephone wires is loudest when the wires are tightly stretched as they often are during cold weather.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">9. If it is red sky at sunset, does this mean that the next day is going to be an excellent day?</a> <div class="expandContent pane"><p>The logic behind "red sky at morning, sailors take warning; red sky at night, sailors delight" is that if the sky is red in the morning, any clouds would be to the west, which is the direction from which clouds usually come from in Canada. Conversely, if the sky is red at night (dusk) the clouds would have departed. The red tinge to the sky suggests dry air and the presence of particles that help to preferentially scatter red light towards us. If the dry air is to the east, wet weather may be on the way whereas if the dry air is toward the west, this would indicate fair weather is on the way.</p><p>But there are many times when this saying does not hold true. For example, some summer nights can feature a red sky in the evening, only to be followed by overnight thunderstorms. Conversely, a red sky in the morning could occur during the midst of a multi-day dry spell with no rain in sight.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">10. What does it mean when you see a rainbow in the sky early in the morning?</a> <div class="expandContent pane"><p>There is a rhyme, "rainbow in the morning, sailors take warning." Sailors made observations of weather patterns and they noticed that when they saw a rainbow in the early morning, rain was on its way (or very close to happening). A rainbow is formed when light is refracted through water droplets from moisture in the air, which usually means that it is about to rain or that a storm has just passed.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">11. Is there any basis for the belief that a ring around the moon at night means a storm the next day?</a> <div class="expandContent pane"><p>The presence of a ring around the moon indicates that there are ice crystals high in the atmosphere. These crystals are the main components of high-level cirrus clouds, which are often the first clouds to appear when a warm front approaches a given area. Typically, a warm front will be associated with a low pressure system which is commonly referred to as a storm. However, sometimes the low pressure system is not close enough or strong enough to produce precipitation the next day.</p></div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">12. Why "if there is dew on the grass, no rain comes to pass?"</a> <div class="expandContent pane"><p>When dew or frost forms on the ground, it indicates that there are calm winds and clear skies during the night. This is characteristic of strong high-pressure systems which generally will bring sunny skies later in the day and no rain or snow. With no cloud cover overnight the surface of the earth is able to cool close enough to its dew point temperature so that water will be able to condense in the form of dew.</p></div> </div> </div> </div> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_title" id="about-the-weather-network-and-meteorology">About The Weather Network and Meteorology <span class="expand-more">+</span><span class="expand-less">-</span></a> <div class="expandContent pane"> <div class="accordion"> <a onclick="return false;" data-category-level="1" class="expandTitle category_subtitle">1.
