A sudden, sustained surge of wind

A squall is a sudden, sustained increase in wind speed (conventionally a jump of a defined magnitude lasting at least a minute or two, which distinguishes it from a brief gust), typically accompanying showers, thunderstorms, or a frontal passage. The term extends to the squall line, a long organised band of thunderstorms along or ahead of a cold front; Newton's 1950 Structure and mechanism of the prefrontal squall line described the airflow and lifting that organise such a line, and Wallace and Hobbs's Atmospheric science places squalls among convective wind phenomena. The referent is a short-lived but sustained wind surge, and the convective line it names.[1][2]

Unit
A sustained sudden rise in wind speed (and its duration)
Recovery means
Not applicable
Measured by
Logged from anemometer records by the magnitude and duration of the wind-speed increase; squall lines tracked by radar
