A katabatic wind is a gravity-driven wind that carries high-density air from a higher elevation down a slope under the force of gravity. Katabatic winds are common in polar regions, where they can influence local climate, ice dynamics, and the formation of ice shelves. They are significant in meteorology and polar research.
