浪致混合效应的耦合模式模拟

fter 21ST century, marine scientists begin to pay attention to the ocean wave's effect on the other ocean dynamic processes, such as surface wave-induced mixing in the upper ocean mixed layer. In this paper, the parameterization scheme of the mixing due to turbulence generated by wave-induced motion is added to the coupled ocean-atmosphere-wave-sediment transport modeling system(COAWST). The response of ocean to hurricane with the modified coupled modeling system which contains parameterization schemes of effects of the wave breaking and wave-induced motion on the mixing are investigated by idealized hurricane cases. In these idealized cases, the sea surface temperature will be decreased, and the mixed layer depth, turbulence kinetic energy(TKE), vertical viscosity coefficient(AKV) and dissipation of TKE will be increased if the effects of the wave breaking and wave-induced motion on the mixing are considered. Wave-induced motion can effectively transfer the turbulent kinetic energy to the deeper ocean and enhance the mixture of the upper ocean. Furthermore, the parameterized schemes of mixing due to turbulence generated by wave breaking and wave-induced motion which are embedded in the k-ω turbulent mixing scheme are feasible.
