A squall is a sudden, strong burst of wind, often with rain, snow, or storms. It usually comes quickly, makes a lot of noise and disturbance, and then passes.
Probably from a Scandinavian source, related to Norwegian “skval” meaning “sudden breeze” or “splashing, squawking sound.” The word imitates the noisy, sharp nature of sudden wind and waves.
“Squall” sounds noisy and harsh, and that’s exactly what it describes—nature having a short, loud outburst. The same root is connected to loud cries, so a baby can “squall” too, like a tiny personal storm.
