摘要：

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/s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 ocean wave model and a linear storm surge model are adopted to investigate effects of storm surges on ocean waves in a closed rectangular basin.Refractions of ocean wave caused by temporal and spatial variations of water depth and currents are included in the wave model. Computational tests at different wind speed and water depth indicate that when water depth is 10m and wind speed 30m/s,the maximal relative change in wave height is up to 39%; while water depth exceeds 40m,even if wind speed is 40m/s, the maximal relative change is less than 5%.
