Definition: an empirical measure for describing wind velocity based mainly on observed sea conditions. (noun)
Beaufort #:
- Sea Conditions (wave height in meters)
- 0 Flat (0 meters)
- 1 Ripples without crests (0.1 meters)
- 2 Small wavelets. Light breeze. Crests not breaking (0.2 meters)
- 3 Large wavelets. Crests begin to break. Scattered whitecaps (0.6 meters)
- 4 Small waves. Moderate breeze (1 meter)
- 5 Moderate longer waves. Some foam and spray (2 meters)
- 6 Large waves with foam crests and some spray. Strong breeze (3 meters)
- 7 Sea heaps up and foam begins to streak. Moderate gale (4 meters)
- 8 Moderately high waves with breaking crests (5.5 meters)
- 9 High waves with dense foam. Strong gale (7 meters)
- 10 Very high waves. Visibility is reduced. Sea surface is white (9 meters)
- 11 Exceptionally high waves. Violent storm (11.5 meters)
- 12 Huge waves. Air filled with foam and spray. Hurricane (14+ meters)
Also Known As: Beaufort Scale
Examples:
