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。
Based on a three-dimensional weakly nonlinear theory of Lagrangianresidual current, this study's diagnostic numerical calculation of summer circulationin the East China Sea and the Yellow Sea using the velocity-spilitting methodand considering the Kuroshio and the Changiiag kiver runoff showed that theTaiwan-Tsushima Warm Current System is the main current system in the continental shelf The sources of the Tsushima Warm Current entering the Korea Straitare the Taiwan Warm Current, the Kuroshio, and the Mixing Water of the EastChina Sea and West Korea Coastal Current. The source of the Yellow Sea WarmCurrent 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 upwellingtakes place are revealed to be in the Zhejiang and Fujian coastal sea, the mouthof the Chanaiing kiver, the northeastem part of the East China Sea and the continental slope. The area of the upwelling and the downwelling along the continentalslope emerge alternately, and the area located on the PN-section is the upwellingarea in the upper layer.
