squall, as used by weather forecasters, a sudden wind-speed increase of 8 metres per second (18 miles per hour) or more, for one minute or longer. It includes several briefer wind-speed changes, or gusts. A squall is often named for the weather phenomenon that accompanies it, such as rain, hail, or thunder; a line squall is one associated with a squall line of thunderstorms that is often hundreds of kilometres long.
