摘　　要：联合第三代浅水海浪模式SWAN和三维海流模式POM,建立考虑海浪影响的三维风暴潮模式,利用该模式,在渤黄海区域,对温带气旋830315诱发的风暴潮进行数值模拟.从海表风应力、辐射应力、底应力三方面入手。对海浪对风暴潮的影响进行了数值研究.研究表明;海浪通过风应力对风暴湖水位的影响最为显著,而波致辐射应力与依赖波流相互作用的底应力的影响只在渤海和北黄海相对明显;考虑海浪影响的风暴潮水位过程曲线模拟结果,比不考虑海浪影响的纯风暴湖模拟结果与实测水位曲线吻合的更好,尤其是在减水极值处,其相对误差不超过5.57%。A 3-D storm surge model was developed which consists of the third generation shallow water wave model SWAN and the 3-D current model POM and was applied to test for the storm surge of Bohai Sea and Yellow Sea caused by extratropical cyclone 830315. The influence of waves on sea level through sea surface stress, radiation stress and bottom stress was obtained. The study shows that the wave-dependent surface wind stress can more significantly improve the storm surge prediction than the wave-induced radiation stress and wave-induced bottom stress, but they all can not be neglected. The study further indicates that the results computed by the model considering the influence of waves on storm surges are more in good agreement with the measured data, especially on the water reduced peak surge, the relative errors are not more than 5.57%.
