摘　　要：杭州湾自然地理条件特殊、社会经济发达,研究杭州湾内台风浪特征对该地区的防灾减灾具有重要的现实意义。现选用藤田台风模型模拟台风场,采用基于动谱能量平衡方程的SWAN模型模拟台风浪,计算了台风Winnie过程中杭州湾内的波浪情况。通过分析台风过程中不同时刻杭州湾内波高分布图,得到波高的空间分布变化规律;并将波高数据进行回归分析,得到了杭州湾内波高与风速和水深的相关关系。Hangzhou Bay which has a special geometry is one of the most developed areas in China,and always exposed to typhoon attacks.It is important to study the wind wave caused by typhoon.In the present study,Fujita model is used to model typhoon,and SWAN is used to model wind wave.Wind and wind wave in Hangzhou Bay is computed during the typhoon Winnie.The developing process of wind wave during the typhoon is paid attention and the relationship between significant wave height and water depth,wind velocity is obtained.
