noun
A meteorological term for a wind that carries high-density air down a slope under gravity; often cold and associated with glaciers or plateaus.
南極ではカタバチック風がよく観測される。
Katabatic winds are frequently observed in Antarctica.
滑降風 is a less common Japanese synonym for katabatic wind, while カタバチック風 is the standard loanword-based term used in meteorology.
From English 'katabatic' (ultimately from Greek katabatikos 'descending') + 風 (かぜ, 'wind').
