Katabatic wind flow
Did you know?
A katabatic wind (named from the Greek word κατάβασις katabasis, meaning "descending") is a drainage wind, a wind that carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds; the spelling catabatic winds is … Visa mer A katabatic wind originates from radiational cooling of air atop a plateau, a mountain, glacier, or even a hill. Since the density of air is inversely proportional to temperature, the air will flow downwards, warming approximately Visa mer • Anabatic wind • Foehn wind • Valley exit jet • Bora (wind) Visa mer • Media related to katabatic wind at Wikimedia Commons Visa mer 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. Where … Visa mer • Giles, Bill.

The gentler katabatic flows of hill slopes produce frost hollows. Mountain breezes are part of a local wind system.

Katabatic winds drive sea ice export from glaciated fjords across Greenland and other high latitude environments, but few studies have investigated the extent to which they also drive inflow of warm water and whether they have a direct impact on glaciers stability.
