北部湾是一个半封闭的超浅海。本文在数值试验的基础上，提出了一个研究该海域台风风暴潮的数值模型。数值模式为二维深度平均流模型，采用嵌套细网格技术，细网格分辨率为沿经纬方向０．１°，细网格边界值由粗网格提供。台风风场计算采用Ｊｅｌｅｓｎｉａｎｓｋｉ模型风场．模式方程组的数值解由交替方向隐式（ＡＤＩ）方法积分得到。本文对该海域最常见的两种台风移行所引起的风暴潮进行了数值模拟。与几个潮汐观测站的增水记录比较，计算结果基本上反映了台风引起的水位变化，对研究和模拟该海域台风风暴潮是适用的，可用于该海域风暴潮数值预报试验。
North Bay is a semi-enclosed super-shallow sea. Based on numerical experiments, this paper presents a numerical model to study typhoon storm surges in this area. The numerical model is a two-dimensional depth averaged flow model, using nested fine grid technology, the fine grid resolution is 0.1 ° along the latitude and longitude direction, and the fine grid boundary value is provided by the coarse grid. Typhoon wind field calculation using Jelesnianski model wind field. The numerical solution of the system of equations is obtained by integration of alternating direction implicit (ADI) methods. In this paper, the two most common typhoon transitions in this area are numerically simulated. Comparing with the water record of several tide stations, the results basically reflect the typhoon-induced changes in water level, which is suitable for studying and simulating the typhoon storm surge in this area. It can be used for the numerical prediction of storm surges in this area.
