| 摘 要： | 本文利用ＮＯＡＡ卫星图像处理结果与同期水文观测资料，对东海表层水团的分布和转移特征作了初步分析。结果表明，东海表层水温的分布与结构同该海区的水团和环流发展相联系，水团消长和东海冬季高密水核心上层环流的发展可诱导长江口外混合水向外海扩散，表层水块的移动速度可达２６ｃｍ／ｓ，与动力学估算和同期漂移浮标所得的结果一致

| Abstract: | The features of distribution and transformation of the East China Sea surface water mass are analyzed by using NOAA satellite images and simultaneous hydrographic data. The results are as follows: The distribution and the structure of surface water temperature in the East China Sea are associated with the interaction between water masses and the development of the East China Sea dense water circulation. The development of upper circulation on the core area of the East China Sea winter dense water can induce the mixing water off Changjiang mouth to diffuse to offshore. The movement speed of the surface water body with special shape can reach 26cm/s. This value is consistent with the dynamic estimation and the simultaneous observation result from drifting buoy. |
