采用一种半隐式三维海洋紊流模型对杭州湾及长江口附近的潮流场进行了数值模拟 .该模型在垂向上采用σ坐标 ,可以较精细地处理表面和底层、较好地模拟地形的垂向变化和密度分层对潮流场的影响 .潮汐流的潮位和潮流流速的二维、三维模拟结果与实测结果符合良好 .
A semi-implicit three-dimensional oceanic turbulence model was used to simulate the tidal current near Hangzhou Bay and the Changjiang Estuary. The model uses σ coordinate in the vertical direction, which can deal with the surface and the bottom layer more finely, Vertical variation and density layer on tidal flow field.The two-dimensional and three-dimensional simulation results of tidal current tidal current and tidal current velocity are in good agreement with the measured results.
