摘    要:海洋的上混合层可近似为温度、盐度和余流的垂直均匀层,如同大气的充分混合层一样.稳定度很大的跃层可看作是流的一个物质面,由此推理混合层内的余流通量可视为是水平无辐散的.本文以物理模型的方法设计了在渤、黄、东海海域求解多连通区域无辐散流的数值解法,研制了一个适用于上混合层积分模式的余流客观分析方法,并用多年平均的8月的余流和混合层深度的观测资料求解了无辐散流场,结果与被海洋学者认知的基于实测资料分析的渤、黄、东海环流图较好地一致.

关 键 词:渤、黄、东海  上混合层  无辐散流场  跃层  余流  物质面  物理模型法

Abstract:The ocean surface mixed layer can be approximated to a vertical uniform layer on temperature, salinity and current. We regard the transition layer as a boundary plane if it has high stability and infer that the rate of discharge in the mixed layer is non-divergent horizontally from the precondition. There is a numerical method to explain the non-divergent flow function of the connected region in the East China Sea by a physical modeling-A method of analyzing the stable current of the upper mixed layer which adapts to the integral modeling. Based on the marine data of current and depth of the mixed layer, we explain the non-divergent flow field in August. As a result the result accords with the authoritative information of the East China Sea which is based upon the analysis of the observed data.
Keywords:the East China Sea  the sea surface mixed layer  non-divergent flow field  transition layer  stable current  physical modeling
