采用第三代海浪模式和线性全流风暴潮模式计算封闭海域内风暴潮对风浪的影响。海浪模式中包含水深变化及平均流变化引起的波浪绕射项。计算了不同风速和不同静水深情况下风暴潮引起的风浪波南的变化。计算结果表明：静水深为１０ｍ及风速为３０ｍ／３时，风暴潮引起的风浪波高的相对变化的最大值达３９％；而静水深超过４０ｍ时，即使风速为４０ｍ／ｓ，风暴潮引起的风浪波高的相对变化的最大值小于５％。
The third generation wave model and the linear all-flow storm surge model are used to calculate the influence of storm surge on the sea wave in the closed sea area. Wave patterns include changes in water depth and the average flow changes caused by the wave diffraction items. The variation of wind and wave wave south caused by storm surge under different wind speed and different hydrostatic depth was calculated. The results show that the maximum value of the relative change of the wave height caused by storm surge is 39% when the static water depth is 10m and the wind speed is 30m / 3. When the water depth is more than 40m, the wind speed is 40m / s, The maximum relative change of the wave height is less than 5%.
