| 摘 要： | 在POM的基础上 ,建立一个σ坐标系下的三维斜压预报模式 ,考虑了海底地形、外来流、长江径流、海面风应力、海面热交换等多方面因素的影响 ,较好地模拟了夏季东中国海环流的情况。其结果表明 ,黑潮在流经东海时沿东海陆坡流动 ,其途径随陆坡等深线走向而变 ,在其两侧出现一些涡旋。夏季台湾暖流上层水主要来自台湾海峡 ,底层水主要由台湾东面黑潮的次表层水入侵陆架生成。夏季进入朝鲜海峡的对马暖流的来源是多方面的 ,其中有 :台湾暖流、黑潮分支、长江冲淡水与西朝鲜沿岸流的混合水。长江冲淡水在出长江口后 ,很快转向北流动 ,到34°N附近转向东南方向。在长江口东北面存在两个中尺度的涡旋。夏季黄海冷水环流由南北两部分组成 ,表层流速大 ,底层流速小。在青岛 石岛附近还存在一个中尺度的反气旋型涡旋

| Abstract: | dimension baroclinic prognostic model on the σ coordinate is established based on POM to simulate the summertime circulation of East China Seas, considering the topography, inflow and outflow on the open boundary, Yangtse River runoff, heat flux and wind stress on the surface. The result shows that, the Kuroshio flows along the continental slope of the East China Seas, its trajectory varies with the slope topograph, and some eddies appear on the both sides of it. In the summer, the upper water of the Taiwan Warm Current is mainly from the Taiwan Strait, and its bottom water is mostly from the sub surface water of the Kuroshio which flows on the shelf while passing through the east of Taiwan Island. The water of the Tsushima Warm Current is of multi source in summer: the Taiwan Warm Current, the branch of the Kuroshio, the mixed water of the Yangtse Diluted Water with the West Korea Coast Current. The Yangtse River Diluted Water quickly turns to north after it flows out the Yangtse River Mouth and then flows southeastward when it arrives at about 34° N. There are two meso scale eddies northeast of the Yangtse River Mouth. In the summer, the Huanghai Cold Circulation is divided into the north and south ones, and surface current is strong and the bottom current is weak. There is a meso scale anticyclone addy near Qingdao and Shidao. |
