Morphology
The adjective 'katabatic' denotes descending air, so when combined with the noun 'wind' the phrase directly means wind produced by downward-moving air; this follows a standard adjective + noun compositional pattern. Although 'katabatic' is a technical/rare word, if a learner already knows that constituent meaning the compound’s overall sense is predictable and transparent.
Etymology
The noun katabatic wind comes from a simple image: the katabatic part is very cold, heavy air rushing down a mountainside, and the wind part is the strong movement of that air. So, katabatic wind means a wind made when cold air moves 'down' a slope into the valley below.
