It is obtained by taking the ratio of the amplitude two first order Bragg peaks (the same signal that is used for current measurement except there we use the frequency of the peaks) and applying a directional wave model. The wind statistics are based on real observations from the weather station at Botany Bay/Sydney Airport.
