中文摘要：

波浪辐射应力引起的增水是风暴增水的重要组成部分，研究台风过程中波浪辐射应力在风暴增水中的作用对于准确预报风暴潮有十分重要的意义。选用藤田台风模型模拟台风场，采用SWAN模型模拟台风浪以及辐射应力，应用垂向积分的二维数学模型ADCIRC计算风暴潮。首先模拟理想地形条件下，规则波和不规则波斜向岸边入射过程中的波浪变化，研究波高、波浪辐射应力和增水的沿程分布特征；然后计算了台风Winnie过程中浙江沿海的波浪情况，通过计算得到了波浪辐射应力增减水的空间分布特征和随时间的变化趋势，并分析了其对风暴增水的影响。

英文摘要：

Wave radiation stress is one of the most important dynamic factors in a storm surge. The effect of wave radiation stress on storm surge is studied numerically. Fujita typhoon model is applied to simulate typhoon wind and pressure,SWAN wave model is used to simulate wind wave, and ADCIRC model is used to simulate storm surge in this paper. First the wave height, wave radiation stress and wave setup in an ideal slope topography in cases of obliquely incident regular and irregular waves are studied. Then by simulating waves and storm surge during the typhoon Wirmie in the coastal area of Zhejiang Province, the water setup caused by wave radiation stress is obtained and the effect of wave radiation stress on a real storm surge is discussed.
