摘　　要：以QSCAT/NCEP混合风资料和Myers经验模型风场构造台风风场,并以之作为驱动风场,建立一个基于第三代海浪模式SWAN的两重嵌套台风浪数值模拟模型。以0601号台风珍珠为例,对南中国海至广东的台风浪进行数值模拟研究。将数值模拟结果与台风期间Jason-1卫星高度计观测资料和近岸浮标实测资料(波高、波向和波周期)作了较为详细地比较,并分析台风浪要素的时空分布。结果显示台风浪要素的数值模拟值与实测值吻合良好,表明SWAN模型能够较好地再现大洋和近岸台风浪的时间发展过程和空间分布特征。With the driven wind incorporating the Myers typhoon model and the QSCAT/NCEP blended wind,a two-nested domain typhoon wave model is developed based on the third generation wave model SWAN.As a case study,typhoon Chanchu（0601） is selected to simulate waves from South China Sea to Guangdong province.Analysis of the numerical typhoon wave distribution in time and space is made and comparisons of the model data with those of observation by the Jason-1 satellite altimeter and the nearshore-located wave recorder show good results.It is concluded that the SWAN model could reasonably reproduce the features of typhoon waves in ocean and coastal waters spacially and temporally.
