| 摘 要： | 以自适应数值模型首次计算整个东中国海三维 M2 分潮潮致 Euler余流、Stokes漂流和L agrange余流 ,并分析各海区 L agrange余流的特征。渤海 M2 分潮致 L agrange余流在整个海域基本形成一个大的逆时针环流系统 ;辽东湾有一个逆时针流环。在黄海 ,潮致余流也是黄海环流的重要组成部分。在东海的东北部 ,潮致余流有强化对马暖流的作用 ;在台湾北部海域 ,潮余流对台湾暖流有强化作用。在近海海域 ,由于复杂地形的作用 ,潮流非线性作用加强 ,潮余流的量值有较明显的增加。计算结果表明 :在浅水区域 ,Stokes漂流较大 ,Euler余流与 Lagrange余流差别显著

| Abstract: | Self adaptive numerical model is used to simulate the 3 D tide induced Euler, Stokes and Lagrangian residual currents in the East China Sea for the first time.The character of Lagrangian residual current in each area is analysed. In the Bohai Sea, Lagrangian residual current of the M 2 tide basically forms a large anticlockwise circulation; there is an anticlockwise circulation in the Liaodong Bay. In the Huanghai Sea, tide induced residual current is also an important part of its circulation. In the northeast part of the East Sea, tide reduced current makes Tsushima Warm Current stronger. In the area northern of Taiwan, tide reduced current makes Taiwan Warm Current stronger. In the coastal seas, the nonlinear interaction of tide and tide reduced current are stronger due to the comflex topography. The results show that stokes residual current is stronger in shallow seas, and Euler residual current is very different from Lagrangian residual current. |
