kaus
From Glossary of Meteorology
(Also spelled quas;
also called cowshee, sharki.) A moderate to gale-force southeasterly wind in the Persian Gulf; it is accompanied by gloomy weather, rain, and squalls.
The kaus is most frequent between December and April. It is associated with the passage of a winter depression, and is often followed by a strong southwesterly wind, the suahili.
