Katabatic wind, also called downslope wind, or gravity wind, wind that blows down a slope because of gravity. It occurs at night, when the highlands radiate heat and are cooled. ... This process is most pronounced in calm air because winds mix the air and prevent cold pockets from forming.
What causes katabatic winds?
Definition: Sounding almost like acrobatic winds, katabatic winds do bear a resemblance to tumbling, since they are essentially winds that flow downhill. Also known as fall winds, katabatic winds are usually caused by gravity pulling higher density air downslope to lower density air.
Where do katabatic winds occur?
Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica and Greenland. The buildup of high density cold air over the ice sheets and the elevation of the ice sheets brings into play enormous gravitational energy.
