A Model for the Response of Wave Directions to Changing Wind Directions for Random Breaking Waves
On the basis of the wave energy balance equation, a model for the response for random breaking waves is derived. The results show that, the dissipations of white-capping tend to increase rather than to slow down the turning rate induced by the wind generation. For fully developed wind waves, the dissipation due to white-capping forces the mean wave directions to turn to the wind directions. This model can be used in the case of random nonbreaking waves, and the models for slowly turning wind directions and in inhomogeneous situations are derived with the same methods.
