摘要:
基于拉格朗日余流及其输运过程的一种三维空间弱非线性理论,引进了黑潮边界力及长江径流,给出了东海和南黄海的夏季环流及上升流区的分布。计算结果表明:在黑潮西侧存在着台湾-对马暖流系统;进入朝鲜海峡的对马暖流来自台湾暖流、黑潮、东海混合水和西朝鲜沿岸流;黄海暖流主要来源于东海混合水,表层有部分来自对马暖流;闽浙沿岸存在上升流区且构成一带状区域;在长江口外、东海东北部和陆被上也存在上升流区;陆坡处上升流和下降流区交替出现,PN断面上为上升流区。

BAROCLINC MODEL OF SUMMER CIRCULATION IN THE EAST CHINA SEA AND SOUTH YELLOW SEA
Wang Hui
Abstract:
Based on a three-dimensional weakly nonlinear theory of Lagrangian residual current, this study’s diagnostic numerical calculation of summer circulation in the East China Sea and the Yellow Sea using the velocity-spilitting method and considering the Kuroshio and the Changjiang River runoff showed that the Taiwan-Tsushima Warm Current System is the main current system in the continental shelf. The sources of the Tsushima Warm Current entering the Korea Strait are the Taiwan Warm Current, the Kuroshio, and the Mixing Water of the East China Sea and West Korea Coastal Current. The source of the Yellow Sea Warm Current is the Mixing Water of the East China Sea, but partly coming from the Tsushima Warm Current in the upper layer. The main areas where upwelling takes place are revealed to be in the Zhejiang and Fujian coastal sea, the mouth of the Changjiang River, the northeastern part of the East China Sea and the continental slope. The area of the upwelling and the downwelling along the continental slope emerge alternately, and the area located on the PN- section is the upwelling area in the upper layer.
