采用一维湍动能模式对南海南部的 SST及混合层进行数值模拟和数值试验。结果表明 :TKE模式能够模拟南海南部的海表面温度 SST以及除南海南部 5月中旬以外的上混合层深度随时间变化基本特征。在 5～ 6月 ,SST的日振荡主要依赖于短波辐射的日变化 ,风的混合作用抑制了 SST的日周期振荡。春季夏季风爆发期间 ,南海海面潜热通量和感热通量与短波辐射和风应力相比较 ,是一个对 SST和混合层影响较小的量。在春季南海南部 ,短波辐射作用能使 SST升高的最大值约为 4℃ ;潜热和感热通量能使 SST的下降的最大值为 3℃。风应力对南海混合层深度随时间变化趋势起着决定的作用 ,并能使其深度加深 2 0～ 30 m,而短波辐射则使混合层的深度变浅2～ 3m,潜热和感热通量会使混合层的深度加深 1～ 2 m。在春季南海南部 ,热通量对混合层深度的影响与风应力相比要小得多
One-dimensional turbulent kinetic energy model is used to simulate and simulate the SST and mixed layers in the southern South China Sea. The results show that the TKE model can simulate the SST of the sea surface in the southern South China Sea and the basic features of the depth of the upper mixed layer over time except for the middle of May of the South China Sea. From May to June, the daily oscillation of SST mainly depends on the diurnal variation of shortwave radiation, and the wind mixing inhibits the daily oscillation of SST. During the onset of the spring monsoon, the latent heat and sensible heat flux in the SCS is a relatively small contribution to the SST and mixed layers compared to the shortwave radiation and wind stress. In the spring, in the southern South China Sea, the maximum value of SST rise caused by shortwave radiation was about 4 ℃, and the maximum of SST drop was 3 ℃ for latent and sensible heat fluxes. The wind stress plays a decisive role in the depth of the mixed layer in the South China Sea over time, and can make the depth 20 to 30 m deeper, while the shortwave radiation causes the depth of the mixed layer to be 2 to 3 m. The latent heat and sensible heat flux Will deepen the mixed layer depth 1 ~ 2 m. In spring, in the southern part of the South China Sea, the effect of heat flux on the depth of the mixing layer is much smaller than the wind stress
