| 摘 要： | 利用湍流动能垂直混合模式和ＴＯＧＡ－ＣＯＡＲＥ加强观测期的观测资料,对“暖池”上混合层的垂直混合过程进行数值试验和数值模拟,分析表层温度、盐度的变化特征。结果表明：ＴＫＥ模式可以较好地模拟混层,尤其是表层温度、盐度对大气局地强迫的响应;太阳辐射是热源,感热、潜热通量等会造成“暖池”上混合层的温度降低,“暖池”对大气释放热量;降水有利于“淡水盖”形成和维持,从则使层结稳定,ＳＳＴ升高。但在气温低于海

| Abstract: | A numerical experiment of the vertical mixed process of "warm pool" mixed layerwas made and the variation characteristics of surface layer temperature and sa1initywere analysed based on the vertical mixed model of the turbulent kinetic energyTKE model) and intensive observation data of TOGA-COARE. The results showthat the TKE model can simulate well the response of temperature and salinity inthe upper mixed layer especially in the surface layer to local atmospheric forcings.Solar radiation is heat source and sensible and latent heat fluxes can decrease thetemperature of the upper mixed layer, the "warm pool" releases heat to atmosp-here. Precipitation is favourable to forming and maintaining a "fresh water lid"so that stabilizes the stratification and increases SST, however, when air temperatureis colder than sea temperature, precipitation decreases SST. The vertical mixing dueto wind stress can cause SST decrease, but it can also redhce the heat flux from seato air so that SST increases. The interaction between local forcings and SST is anegative feedback system. The temperature and salinity of the surface layer haveintraseasonal oscillation characteristics. |
