Webb25 sep. 2024 · Snowfall in Antarctica is a key term of the ice sheet mass budget that influences the sea level at global scale. Over the continental margins, persistent katabatic winds blow all year long and supply the lower troposphere with unsaturated air. We show that this dry air leads to significant low-level sublimation of snowfall. 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 ...
