katabatic
(kāt'ə-bāt'ĭk) Relating to wind currents that blow down a gradient, especially down the slopes of a mountain or glacier. When air comes in contact with the cool surface of a glacier or the upper regions of a mountain or slope, the air cools, becomes dense, and blows downward. Katabatic winds are usually cool and are especially common at night in polar regions. |
