| 摘 要： | 依据自适应数值模型，模拟了东中国海冬、夏季三维斜压Lagrange环流。模拟发现：台湾暖流的上层水来自台湾海峡入流和台湾东北黑潮的表层水；50m以下的深底层水主要由台湾东北黑潮的次表层水入侵陆架生成。冬季对马暖流外海一侧主要由黑潮水构成，而其近陆一侧由台湾暖流和陆架混合水构成，西朝鲜沿岸流在济州海峡汇入对马暖流；夏季它还包含转向后的长江冲淡水。冬季黄海暖流并非对马暖流的直接分支，黄海暖流水是对马暖流水和陆架水混合而成，这与传统观点相悖，而与中韩黄海水循环动力学合作调查结果一致。黄海暖流东西两侧分别为2支向南流动的滑岸流。夏季黄海环流构成基本封闭的逆时针环流。冬季渤海环流主要有一逆时针大环流，但辽东湾的环流是顺时针向的。渤海环流冬强夏弱，水流在渤海海峡北进南出。

| Abstract: | Based on the self-adaptive numerical model, presented in Part I 3-dimentional baroclinic Lagrange circulations in the East China Sea in winter and summer are simulated, The simulation results reveal that the upper layer water of the Taiwan warm current comes from the input of the Taiwan Strait and the surface water of the Kuroshio current northeast of Taiwan. The deep layer water below 50m is mainly formed by the intrusion of the sub-surface water of the Kuroshio northeast of Taiwan onto the continental shelf. In winter on the outer side of the Tsushima warm current, there is mainly the Kuroshio water, and on the other side near the land, there are the Taiwan warm current and mixed water from the continental shelf. The west Korean coastal current merges with the Tsushima warm current in the Cheju Strait. In summer there is also the turned Changjiang River dilute water. In winter the Huanghai Sea warm current is not a direct branch of the Tsushima warm current. The Huanghai Sea warm current is a mixture of the water of the Tsushima warm current and the water from the continental shelf. This is inconsistent with the traditional theory and is consistent with the results of the China and Korea joint investigation of the circulation dynamics of the Huanghai Sea water. On the eastern and western sides of the Huanghai Sea warm current there are 2 branches, flowing southward along the coast. In summer the Huanghai Sea current is basically a closed counter- clockwise circulation. In winter the Bohai Sea current is mainly a large counter-clockwise circulation. But, in Liaodong Bay the circulation is clockwise. The Bohai Sea circulation is strong in winter and weak in summer. The water flows in at the northern part of the Bohai Strait and out at the southern part. |
