Storm classification wind speed

Wind speed on the 1946 Beaufort scale is based on the empirical relationship: [7] v = 0.836 B3/2 m/s. v = 1.625 B3/2 knots (. = 13 8 B 3 {\displaystyle = {\frac {13} {8}} {\sqrt {B^ {3}}}} ) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
