冬至初春黄海暖流的路径和起源

On the origin and path of the Huanghai Warm Current during winter and early spring

主要根据近几年来中韩黄海水循环动力学合作调查结果，结合有关观测资料，进一步分析了冬至初春黄海暖流的路径和起源．与以往类似研究不同的主要有两点：（ｌ）初步探讨了黄海暖流路径的季节和年际变异，并指出这种变异与北向风的强弱密切相关；（２）通过分析济州岛西侧海域混合水的去向，进一步确认了部分混合水绕济州岛运行，并进入济州海峡这一事实．同时，初步揭示进入黄海的混合水，即黄海暖流水，含有更多的东海陆架水成分．

The origin and path of the Huanghai Warm Current(HWC) during winter and early spring are analyzed further on the basis of the observations of the China - Korea Joint Investigation of Ocean Circulation Dynamics in the southern Huanghai sa in the recent years and historical data. The results different from the past similar studies have mainly two aspects: (1 ) The path of the HWC has obvious seasonal and interannual variations. The numerical calculations also show that the variations are closely related to the strength, of the northward wind. (2) It is confirmed further by analyzing the path of the mixed water west of the Cheju-do that a part of the mixed water moves around the Cheju-do and enters the Cheju -haehyop. Meanwhile, preliminary analyses indicate that the mixed water entering the Huanghai Sea, i. e., the HWC water, contains much more components of the East China Sea continental mixed water.
