摘要
本文就近几年作者在黄海南部和东海北部进行调查研究(夏季)的主要成果予以阐述,结论为:(1)南黄海底层冷水可进一步划分为三个次级水团;(2)潮混合对黄海冷水团边界和黄海温跃层等有重要影响,它还形成海面的陆架锋;(3)夏季南黄海上层存在着闭合的密度环流,而黄海沿岸流性质上属锋面强流,济州岛西南存在着气旋式海水运动;(4)黄海暖流不再深入黄海冷水团内部,但其内部可能存在着方向相反的一对弱环流;(5)长江口海区存在着可能是因台湾暖流逆坡行进产生的上升流现象。
Results of recent investigation in southern Yellow Sea and the northern East China Sea in summer show that. 1) the bottom cold water in southern Yellow Sea i.e. Yellow Sea Cold Water Mass could be divided into three secondary water masses: Yellow Sea Native Cold Water, Remainder of Yellow Sea Warm Current Water in winter and spring, Yellow Sea Warm Current Water in summer; 2) the border of the Yellow Sea Cold Water Mass is controlled by tidal mixing, it also forms the continental shelf front and the upwelling in the front zone; 3) because of the tidal mixing the sharp thermoclines in the southern Yellow Sea are distributed in the shallower water areas with sloping bottom, not in the deep valley; 4) a cyclonic density circulation of the cold water mass exists in the up-layer of the southern Yellow Sea; 5) there is a cyclonic water movement from the westsouthern part to Che-ju-do I.; 6) in summer the Yellow Sea Warm Current does not enter into interior of the Yellow Sea Cold Water Mass, but in its interior a couple of weak circulation with opposite directions may exists; 7) in summer the Yellow Sea Coast Current is a jet along the front of the Yellow Sea Cold Water Mass, it has two strong current areas, one is located in the area east of Shandong peninsula, another is outside the Subei Shoal; 8) Taiwan Warm Current has an important effect on the distribution and variation of Changjiang River Diluted Water, near the mouth area of Changjiang River exists an upwelling which may be caused by Taiwan Warm Current going upwards on sloping bottom.* Contribution No. 1624 from the Instifite of Occanology, Academia Sinica.
