摘　　要：以海洋上部混合层(UML)存在为基础,建立了考虑UML深度变化的二维层模式。探讨有限区域的短期海表温(SST)业务数值预报模式。预报方程有三:低频流(黑潮及其分支)的无幅散化余流方程组、动力预报方程和模式物理学方程。本模式用于3～5d的SST预报,同时也给出UML平均漂流的预报。指出在大风状况下的降温,UML深是一个重要的影响因子,并与UML为平底时情况进行了比较。Starting with the characteristics and information of the sea area under research, based on the existence of the upper mixed layer (UML), changing the invariable depth of the UML into the more practical variable depth of the UML on the basis of original model, constructing a two dimensionai(vertically integrated )model of the UML from primitive forecasting equations, this paper studies the sea surface temperature (SST) prediction for a short period (3 to 5 days) in a limited region. Under the forcing of a hurricane the entrainment and pumping are the primary mechanisms that lower the SST. The results obtained from this model are more reasonable than the Original model in which the depth of the UML is constant.
