| 摘要: |
| 模型以经Sigma坐标变换后具有自由表面的三维非线性Navier-Stokes方程为基本方程,采用紊流封闭模型求解垂直方向紊动粘滞系数,建立了一个北部湾的三维风暴潮模型。应用该模型对典型的8007号及8410号风暴潮进行了模拟,风暴潮位的验证较好,并获得了风暴潮流的空间结构特征,揭示了台风引起的北部湾沿岸海水交换。 |

| Abstract: |
| On the basis of 3-D nonlinear Navier-Stokes equations under Sigma tranformations and with free surface, using turbulent closure model to resolve vertical turbulent viscosity coefficient, a numerical model of the Beibu Gulf's storm surges is presented. The model is used to simulate the storm surges driven by typhoons 8007 and 8410 in the Beibu Gulf, the calculated tidal levels fit with the measured data well, and the results reveal the spatial structures of tidal current induced by typhoon and coastal seawater exchanges. |
