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 ... WebSince the surface winds blow from the mountain into the valleys this is called a mountain breeze. The term katabatic wind is a more general term for a high density, gravity driven, downslope or drainage wind. A katabatic wind can affect a much larger area than a simple mountain breeze.
