[ kăt′ə-băt′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. Compare anabatic.
