Influence of the wind waves dissipation processes on dynamics in the water upper layer

Stochastic surface wind waves are considered as an intermediate physical phenomenon responsible for the state of upper layer of the water column. Mathematical formulation of the problem is done by using the wind wave spectral evolution model. It is shown that parameters of the air boundary layer are controlled by input evolution mechanism of wind waves, while dissipation mechanism is important for description of energy and momentum transfer into upper layer of the water column. Estimations of the wave energy dissipation rate are found utilizing the optimized numerical model for wind waves derived earlier. Such estimations can be used for better description of numerous important phenomena at the air–sea surface, including air bubbles entrainment, vertical mixing of oil slicks, near surface shear flow and many others. Three applications of the theory are presented.
