Luftmasser kan dekke hundrevis til tusenvis av kvadratkilometer, og endrer seg sakte i takt med terrenget de er over. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Klassifisering">Klassifisering</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Luftmasse&veaction=edit&section=1" title="Rediger avsnitt: Klassifisering" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Luftmasse&action=edit&section=1" title="Rediger kildekoden til seksjonen Klassifisering"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Luftmasser blir klassifisert ut fra temperaturen og fuktinnholdet sitt. Temperaturen til en luftfmasse blir definert som enten <i>Arktisk</i>, <i>Polar</i> eller <i>Tropisk</i>, der den arktiske luften er den kaldeste og den tropiske luften den varmeste. Fuktinnholdet til en luftmasse defineres som enten <i>Maritim</i> eller <i>Kontinental</i>. Disse blir så brukt i kombinasjon med hverandre. For eksempel er en <i>martitim tropisk</i> luftmasse varm og fuktig, mens en <i>kontinental arktisk</i> luftmasse er kald og tørr. </p> <div class="mw-heading mw-heading2"><h2 id="Bevegelser_og_fronter">Bevegelser og fronter</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Luftmasse&veaction=edit&section=2" title="Rediger avsnitt: Bevegelser og fronter" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Luftmasse&action=edit&section=2" title="Rediger kildekoden til seksjonen Bevegelser og fronter"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Luftmassene kan endre egenskapene sine etter hvilket terreng de er over. En kald arktisk luftmasse er mest vanlig i arktiske områder, og en maritim luftmasse oppstår hovedsakelig over <a href="/wiki/Vann" title="Vann">vann</a>. Luftmassene kan så flytte på seg, og en maritim luftmasse som flytter seg over land vil etter hvert miste fukten sin og bli kontinental. På samme måte kan en tropisk luftmasse som flytter seg nordover bli avkjølt og bli polar eller arktisk. Grensene mellom to forskjellige luftmasser er myke, men en har ofte et smalt område i overgangen mellom to luftmasser. Dette området kaller vi en <a href="/wiki/V%C3%A6rfront" title="Værfront">værfront</a> eller en frontsone, og ofte kan vi se disse frontene i form av synlige værfenomen. Luftmasser blander seg sjelden sammen, og flytter seg heller rundt og erstatter hverandre. De tilhørende frontene flytter seg også, og fører til endringer i <a href="/wiki/V%C3%A6r_(meteorologi)" class="mw-redirect" title="Vær (meteorologi)">været</a> på overflaten under. Fronter blir også oppkalt etter luftmassen som presser den bort, og vi kaller det en <a href="/wiki/Kaldfront" title="Kaldfront">kaldfront</a> når en kaldere luftmasse erstatter en varmere luftmasse. </p><p>Luftmasse er derimot ikke det samme som småskalafenomen som <a href="/wiki/Mikroutbrudd" title="Mikroutbrudd">mikroutbrudd</a>. Disse småfenomenene involverer også luftmasser, men uttrykket luftmasse blir bare benyttet for værsystemer over store områder. </p> <div class="mw-heading mw-heading2"><h2 id="Andre_luftmasser">Andre luftmasser</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Luftmasse&veaction=edit&section=3" title="Rediger avsnitt: Andre luftmasser" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Luftmasse&action=edit&section=3" title="Rediger kildekoden til seksjonen Andre luftmasser"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>I Europa blir en <i>ekvatorial</i> luftmasse definert som en luftmasse som har sitt opphav nær ekvator og som skiller seg fra tropiske luftmasser som utvikler seg i subtropiske strøk.
