The Role of Katabatic Winds on the Antarctic Surface Wind Regime

WebbA key feature of coastal or latent heat polynyas are katabatic winds (Fig. 1), which form as cold, dense air masses over the ice sheets of Antarctica. These air masses flow as gravity currents, descending off the glacier, sometimes funneled by topography, as in the Terra Nova Bay polynya whose katabatic winds form in the Transantarctic Mountains.

"WebbKatabatic wind was known before the research of Antarctica, but nowhere else people have met such a powerful wind of this kind (katabatic winds in Greenland have comparable power). This strength can be explained by the half-moon form of the bay – streams of air are squeezed here together and thus forced to flow faster. " - Katabatic antartica winds

Description: Couches limites atmosphériques en Antarctique ...

WebbKatabatic 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 mass from higher elevations displaces the ...
