Radiation fog is most common in autumn and early winter.

It is most common at sea when moist air encounters cooler waters, including areas of cold water <a href="/wiki/Upwelling" title="Upwelling">upwelling</a>, such as <a href="/wiki/San_Francisco_fog" title="San Francisco fog">along the California coast</a>. A strong enough temperature difference over water or bare ground can also cause advection fog. </p><p>Although strong winds often mix the air and can disperse, fragment, or prevent many kinds of fog, markedly warmer and humid air blowing over a snowpack can continue to generate advection fog at elevated velocities up to 80 km/h (50 mph) or more – this fog will be in a turbulent, rapidly moving, and comparatively shallow layer, observed as a few centimetres/inches in depth over flat farm fields, flat urban terrain and the like, and/or form more complex forms where the terrain is different such as rotating areas in the lee of hills or large buildings and so on. </p><p>Fog formed by advection along the California coastline is propelled onto land by one of several processes. A cold front can push the marine layer coast-ward, an occurrence most typical in the spring or late fall. During the summer months, a low-pressure trough produced by intense heating inland creates a strong pressure gradient, drawing in the dense marine layer. Also, during the summer, strong high pressure aloft over the desert southwest, usually in connection with the summer <a href="/wiki/Monsoon" title="Monsoon">monsoon</a>, produces a south to southeasterly flow which can drive the offshore marine layer up the coastline; a phenomenon known as a "southerly surge", typically following a coastal heat spell. However, if the monsoonal flow is sufficiently turbulent, it might instead break up the marine layer and any fog it may contain. Moderate turbulence will typically transform a fog bank, lifting it and breaking it up into shallow convective clouds called <a href="/wiki/Stratocumulus" class="mw-redirect" title="Stratocumulus">stratocumulus</a>. </p><p><b>Frontal fog</b> forms in much the same way as stratus cloud near a front when raindrops, falling from relatively warm air above a frontal surface, evaporate into cooler air close to the Earth's surface and cause it to become saturated. The water vapor cools and at the dewpoint it condenses and fog forms. This type of fog can be the result of a very low frontal stratus cloud subsiding to surface level in the absence of any lifting agent after the front passes. </p><p><b>Hail fog</b> sometimes occurs in the vicinity of significant <a href="/wiki/Hail" title="Hail">hail</a> accumulations due to decreased temperature and increased moisture leading to saturation in a very shallow layer near the surface. It most often occurs when there is a warm, humid layer atop the hail and when wind is light. This ground fog tends to be localized but can be extremely dense and abrupt.

Many lives are lost each year worldwide from accidents involving fog conditions on the highways, including <a href="/wiki/Multiple-vehicle_collision" title="Multiple-vehicle collision">multiple-vehicle collisions</a>. </p><p>The aviation travel industry is affected by the severity of fog conditions.

It involved burning enormous amounts of fuel alongside runways to evaporate fog, allowing returning fighter and bomber pilots sufficient visual cues to safely land their aircraft.

The fog is dense enough to be illuminated by light that passes through gaps in a structure or tree, but thin enough to let a large quantity of that light pass through to illuminate points further on. As a result, object shadows appear as "beams" oriented in a direction parallel to the light source. These voluminous shadows are created the same way as <a href="/wiki/Crepuscular_rays" title="Crepuscular rays">crepuscular rays</a>, which are the shadows of clouds.

Sound is affected during fog conditions due to the small distances between water droplets, and air temperature differences. </p><p>Though fog is essentially liquid water, the many droplets are separated by small air gaps. High-pitched sounds have a high frequency, which in turn means they have a short wavelength. To transmit a high frequency wave, air must move back and forth very quickly. Short-wavelength high-pitched sound waves are reflected and refracted by many separated water droplets, partially cancelling and dissipating their energy (a process called "<a href="/wiki/Damping_ratio" class="mw-redirect" title="Damping ratio">damping</a>"). In contrast, low pitched notes, with a low frequency and a long wavelength, move the air less rapidly and less often, and lose less energy to interactions with small water droplets. Low-pitched notes are less affected by fog and travel further, which is why <a href="/wiki/Foghorn" title="Foghorn">foghorns</a> use a low-pitched tone.<sup id="cite_ref-32" class="reference"><a href="#cite_note-32"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup> </p><p>A fog can be caused by a temperature inversion where cold air is pooled at the surface which helped to create the fog, while warmer air sits above it. The inverted boundary between cold air and warm air reflects sound waves back toward the ground, allowing sound that would normally radiate out escaping into the upper atmosphere to instead bounce back and travel near the surface. A temperature inversion increases the distance that lower frequency sounds can travel, by reflecting the sound between the ground and the inversion layer.<sup id="cite_ref-33" class="reference"><a href="#cite_note-33"><span class="cite-bracket">[</span>33<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Record_extremes">Record extremes</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fog&action=edit&section=10" title="Edit section: Record extremes"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Particularly foggy places include<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
