Beaufort scale A scale of values, from 0 to 12, for describing wind strength, as defined by Admiral Sir Francis Beaufort (1774–1857) in 1806 (the scale was accepted by the British Admiralty in 1838 and adopted by the International Meteorological Committee in 1874). Each wind force is recognized by its common effects on objects in the landscape (dust, flags, trees, etc.) and on people in the open, or on the state of the sea surface.
