williwaw - n., a sudden squall of cold land air from a mountainous coast in high latitudes; a sudden violent wind; a commotion.
Especially common in the Straits of Magellan and the Aleutians. They also happen along Greenland, but are (according to Wikipedia) called piteraq there. Origin unknown, first citation (to British seamen) is from c. 1840.
(And, yes, they're katabatic winds.)
