MODELING THE SURFACE LAYER ABOVE SEA WITH PARAMETERIZATION OF STRATIFICATION AND THE ELEMENTS OF THE WIND WAVES INFLUENCE

Bulgakov K.Yu., Fokina K.V.

The previously created one-dimensional model of wave boundary layer (hereinafter — WBL) was extended by including equations heat and vapor turbulent diffusion, formulas of heat surface flux and surface evaporation, stability functions for dissipation and turbulent coefficient. The numerical and input parameters of the model are described. The wave spectrum used in the model is considered. The set of experiment of simulating of stratified WBL structure under different condition was run. Coefficients of momentum (drag coefficient) heat and vapor exchange were evaluated. The coefficients were compared with the similar coefficients calculated by COARE algorithm; it is the commonly used method of surface turbulent flux calculation. It is shown that stratification has influence exchange in WBL in the cases of moderate and weak wind. Age of wave has an impact on momentum exchange under strong wind. The result could be used for formulating new methods of evaluating of sea surface turbulent fluxes or tuning of existed ones.
