Abstract

<p> Wave-induced turbulent kinetic energy (TKE) plays an important role on the numerical simulation of sea surface mixing. This study has been conducted to improve the parameterization of sea surface turbulent energy fluxes induced by white-capping based on the observation data. The data indicates that TKE fluxes coefficient α proposed by Feddersen and Trowbridge (2005) has dependence on the difference between wave and wind direction. In addition, when the waves follow wind direction, α is weakly dependent on wave steepness. Based on the optimized bulk equation, the coupled atmospheric and ocean simulation of typhoon, Haiyan(2013), has been conducted. The results show the difference on the spatial TKE distribution near sea surface and macroscopic characteristics of typhoon. It is clear that wave-dependence on upper ocean mixing in atmosphere-ocean coupled model is important.</p>
