WebThe relationship between the Beaufort wind level (B) and the wind speed at 10 meters above sea level (v) is approximated by the formula. v = 0.836 B 3 2. Solving for the Beaufort scale number we get the Beaufort Solutions, of which (disregarding imaginary solutions) this is the only one: B = 1.196 v 2 3. The solution to the Beaufort formula can ...
