Description

A williwaw is a sudden blast of wind descending from a mountainous coast to the sea. The williwaw results from the descent of cold, dense air from coastal mountains in high latitudes (Straight of Magellan, Aleutian Islands, Alaskan Panhandle, Greenland). 

Williwaw is considered a type of katabatic wind.
