本文利用黄海南部、东海及台湾以东海域表层流分布图提供的资料作为边界条件,对区域119°~132°E,21°~41°N做数值模拟.模拟出的流场各流系与实测的基本吻合。所得主要结论为:(1)在30°~33°N,125°~128°E这一区域流速小,流向不稳定,它的西、南部分别有流入,东、北部有流出的这一特点与孙湘平所提出的“海水集散”区概念一致、(2)对马暖流不能简单地视为黑潮的分支,应该认为“海水集散区”是它的发源地,此“海水集散区“的水来源是多方面的。
In this paper, the data provided by the surface flow distribution map in the southern Yellow Sea, the East China Sea and the east of Taiwan are used as the boundary conditions to simulate the region 119 ° ~ 132 ° E and 21 ° ~ 41 ° N. The flow field simulated by each flow basically consistent with the measured. The main conclusions are as follows: (1) In the region of 30 ° -33 ° N, 125 ° -128 ° E, the flow velocity is small and the flow direction is not stable. In the west and the south of the region, there are inflows and outflows in the east and north respectively It is consistent with the concept of “seawater collection and distribution” proposed by Sun Xiangping, (2) that the “warmwater distribution” should not be regarded as a branch of the Kuroshio simply because it is the birthplace of the Kuroshio, Sources are many.
