WebUnderstanding the Mechanism of Katabatic Wind. Katabatic wind is a type of downslope wind that is driven by the force of gravity. This force causes the air to accelerate as it descends, creating wind speeds that can reach up to 200 km/h. Katabatic winds are often associated with clear skies, low humidity, and cold temperatures, as the cold air ...

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 also used. Katabatic winds can rush down elevated slopes at hurricane speeds, but mos…
WebIn the traditional model of ridge-valley winds, there are typically two wind regimes on a dry day: a downslope, drainage wind at night due to cooling at the surface along the slopes, and an upslope wind during the day due to solar heating of the slopes.
