【摘要】 首次为整个东中国海设计出一种自适应网格 ,利用自适应网格能同时兼顾网格的光滑性、正交性及疏密程度的特点 ,得到了物理平面上的网格分布。该网格既与边界适应 ,又在水深变化急剧的东海陆坡处得以加密 ,从而使坐标变换下的三维模式成功实现了跨越陆坡的计算。用该模式模拟了海域的潮汐变化。依据所得结果绘制出 M2 分潮的同潮图和潮流椭圆。模拟结果与现有的数值研究结果基本一致 ,表明此模式在该海域的适用性更多还原

【Abstract】 Self adaptive mesh is used in the East China Sea for the first time. The physical plane is obtained by way of self adaptive zoning. The grid points at boundary are corresponding to the actual boundary, and the grid points are denser at the continental slope of East Sea than elsewhere. The tidal wave in the East China Sea is simulated with a 3 D model and the Continental slope is included in the computed area. The distribution of Co amplitude and Co phase lag lines of M 2 and the elliptical axes of tidal current of M 2 for each layer and depth averaged are given. The results agree with those of other authors, and this shows the applicability of the model to the East China Sea.更多还原
