| 摘 要： | 依据黄、东海环流的的动力学模型 ,运用“流速分解法”对黄、东海正压环流进行了数值模拟。计算结果表明冬季黄海正压环流主要受风应力影响 ,基本形态为黄海暖流由济州岛西南进入南黄海中部 ,其东西两侧分别为两支向南流动的沿岸流 ;夏季主要受到潮致体力的影响 ,为一逆时针涡旋。东海环流主要是边界力作用驱动的结果 ,东海黑潮、台湾暖流和对马暖流较稳定。冬季风应力对东海环流表层流场有消弱作用 ,在夏季则有一定增强作用。

| Abstract: | In this paper barotropic circulations in the Huanghai Sea and East China Sea are simulated numerically with a dynamic model proposed in a previous paper.The SCM (Splitting Current Method)is applied to transform the model into a quasi-3-D model.The simulation results show that the barotropic circulations in the Huanghai Sea in winter are mainly affected by!the wind stresses. The basic pattern is that the Huanghai Sea Warm Current is flowing northwards into the middle Huanghai Sea,and two coastal currents are flowing southwards along the shoreline at two sides of the Sea.In summer,however,the barotropic circulations in the Huanghai Sea are mainly driven by the tidal force and form a cyclonic eddy.For the barotropic circulations in the East China Sea,Kuroshio,Taiwan Warm Current and Tsushima Warm Current are relatively stable.Wind-induced current can weaken them in winter,and enhance them in summer. |
