渤海埕北海域风暴潮多年一遇极值增水的数值计算

Numerical Computations of Return Period Set-up Value Induced by Storm Surge in Chengbei Sea Area in Bohai Sea

利用一个二维正压浅海模型和大小区嵌套式的计算格式 ,对埕北海域及其附近连续2 0 a的风暴潮进行了数值模拟 ,并获得了与实测值较为一致的结果。在此基础上对该海区的风暴潮极值增水做出了多年一遇的长期预测。

A two dimensional barotropic shallow sea model and a nesting computational pattern are used to simulate the storm surges occurring in Chengbei sea area and its vicinity in 20 consecutive years. Compared to the measured values, the computed results are rather consistent with the measured ones. Based on the results, the long term prediction of return period set up values induced by storm surge is made.
