| 摘 要： | 通过三维模式导出二维数值模式,采用守恒型空间差分格式对渤海风暴潮进行数值模拟。同时采用由三维模式导出的任意形式的底摩擦表达式,找出适用于渤海风暴潮的底摩擦参数。对曾经发生在渤海的四次较严重的风暴潮进行数值后报并与实测资料相比较,证实预报模式的可行性。

| Abstract: | In this paper, on the basis of numerical simulation, numerical predictions of the Bohai Sea wind surge are made by using a two-dimensional numerical model with real wind fields and a bottom stress formulation derived from a 3-D model. Six parameters of the bottom stress formulation suitable for the Bohai Sea wind surge are discussed and determined from many numerical experiments. By using four real wind fields in the Bohai Sea, the numerical predictions have been carried out The results are in good agreement with observations.With the use of a conservation-type finite-difference form for the space operater, and a new bottom stress formulation, the accuracy of this numerical prediction project is higher than previous numerical simulation projects. |
