From AMS Glossary
(Redirected from Squalls)
- A strong wind characterized by a sudden onset, a duration of the order of minutes, and then a rather sudden decrease in speed.
In U.S. observational practice, a squall is reported only if a wind speed of 16 knots or higher is sustained for at least two minutes (thereby distinguishing it from a gust).
