摘要: 本文从近海异常海温的定义和形成机制出发,在原有的海表温度数值预报模式的基础上,考虑了上层海洋对强天气强迫的动力响应和浅海效应,前者包括卷入和卷出、冷水抽吸和暖水辐聚,后者包括潮混合和浅海对短波吸收之影响,从而建立了一个以混合层的温、流、深度为变量的中国近海异常海温数值预报模式.Abstract: Based on the definition of the offshore SST anomaly (O-SSTA) and its generating mechanism, the predicting model has been established.It is consisted of three parts:equations of dynamics,equations of model's physics and equations of affecting factors of O-SSTA.The latter,which is stressed here,includes the dynamic response of upper ocean on the strong atmospheric forcing and shallow sea effects,such as the entrainment,Ekman pumping, tidal mixing and absorptivity for solar radiation.The predicting variables consist of the temperature (SST),drift current and depth of upper mixed layer.
