Gale

A gale is a strong wind; the word is typically used as a descriptor in nautical contexts.

The U.S. National Weather Service defines a gale as sustained surface wind moving at a speed between 34 and 47 knots (63.0 and 87.0 km/h; 17.5 and 24.2 m/s; 39.1 and 54.1 mph).

[1] Forecasters typically issue gale warnings when winds of this strength are expected.

It is an empirical measure for describing wind speed based mainly on observed sea conditions.

This word is probably of North Germanic origin, related to Icelandic gola (breeze) and Danish gal (furious, mad),[4] which are both from Old Norse gala (to sing), from Proto-Germanic *galaną (to roop, sing, charm), from Proto-Indo-European *gʰel- (to shout, scream, charm away).
