Squall

 

a sudden, brief increase in wind force that is accompanied by changes in wind direction. Wind velocity in a squall often exceeds 20–30 m/sec. A squall lasts several minutes, sometimes with a succession of gusts. Squalls may occur with the approach of storm clouds or clouds preceding atmospheric cold fronts and are often attended by showers, hail, or thunderstorms. Violent squalls can cause great destruction.
