Fairly quiet … Webb5 okt. 2016 · The slope-aligned budgets of momentum and potential temperature are used to define time-scales that describe the evolution of the katabatic flow. Composite wind …
Webb14 feb. 2004 · The katabatic winds do not consistently come from the same westerly direction but vary according to wind speed. Strong katabatic winds overwhelm topographic controls (E-W), and the wind flow is from the south-southwest. Because of this variability we selected a range of 180°–315° for our search criteria.

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.
