摘　　要：为了精细化描述天津沿海台风天气下近岸浪和风暴潮特征,基于非结构三角网格,建立近岸浪与风暴潮的耦合模型,其中台风风场采用藤田台风模型,近岸浪采用SWAN波浪模型,风暴潮采用ADCIRC模型。通过对几次典型台风暴潮数值模拟的验证,耦合模型对风速、有效波高和增水的计算结果与实际观测资料符合性均较好,能够很好地反映台风过程中天津沿海近岸浪和风暴潮特征,可以为天津的防灾减灾工作提供科学依据。In order to reasonably describe the coastal wave and the characteristics of storm surge in Tianjin coastal area, based on an unstructured triangular grid, this paper established a refined coastal wave-storm coupled simulation model. Fujita typhoon wind model was adopted as the wind field, and coastal wave selected SWAN wave model, and storm surge by ADCIRC model. By verifications with numerical simulations of three typical typhoon storms, the computational results of wind speed, significant wave height and storm surge were agreeable with measured data, approving that this coupled model can reflect the coastal wave and the characteristics of storm during a typhoon process in Tianjin coastal area, so as to provide a scientific basis for disaster prevention and reduction in Tianjin.
