东中国海潮波自适应数值模型及其数值模拟Self-Adaptive Numerical Model and Simulation of Tidal Wave in the East China Sea
周旭波,孙文心
摘要(Abstract):
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
