A katabatic wind, from the Greek word katabatikos meaning `to flow downhill`, is the technical name for a drainage wind, a wind that carries high density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds. Katabatic winds can rush down elevated slopes at hurricane speeds, but most.....

Any wind blowing down an incline; the opposite to anabatic wind. If the wind is warm, it is called a foehn; if cold, it may be a fall wind (bora), or a gravity wind (mountain wind).

A cold wind that flows downhill and is powered by gravity. The term is generally used for winds that blow off the Antarctic Plateau toward the coast, although it could also be applied to gully winds.

A local wind produced by the downward motion of cold air off high ground. On clear nights in hilly country, when the air over the higher ground cools because of the radiation into space, it becomes heavier than the air farther from the surface and thus flows downhill on to lower ground. This flow is the Katabatic wind.
