eOceanic - Understanding the Beaufort scale

NettetWind speed on the 1946 Beaufort scale is based on the empirical relationship: v = 0.836 B3/2 m/s. Where v is the equivalent wind speed at 10 metres above the sea surface … NettetIn 1805, in the days of topgallants and royals, Admiral Sir F. Beaufort devised a numerical scale according to which wind velocity or force at sea might be estimated non-instrumentally. 1 According to his scale, the force of the wind was ascertained from the speed imparted to an early nineteenth century man-of-war, the object being to eliminate … NettetBeaufort equivalent scale, which attaches a wind speed value to each Beaufort step, is of great importance especially for the study of air-sea fluxes (Isemer &Hasse, 1991). Since about 100 years many attempts have been made to determine the universal relationship between Beaufort force and wind speed. In any case, equivalent scales are cake fairyland
