复杂岛屿海域的台风浪局地特征模拟与分析——以舟山海域为例

Numerical simulation and analysis of the local characteristics of typhoon waves in multi-islands sea area:An instance of the Zhoushan sea area

为了研究舟山海域复杂地形条件下的台风浪特征,在高分辨数值模拟中采用了利用海图资料处理复杂岛屿地形分布的方法,利用WAVEWATCHⅢ和SWAN模式相嵌套模拟了影响该海域的西北行路径的典型台风浪过程。分析表明,舟山海域的东南部、东北部、西北部、内部海域受台风的影响各不相同,台风浪特征分布与海域的岛屿分布、水深分布等因素密切相关,各个海区的台风浪局地特征明显。

sea area, In order to the progre simulated with the geographical distribu numerical simulation northwest and inside is closely related to t different parts of the study the characteristics of storm waves under varied topography conditions in Zhoushan ss of a typical typhoon storm waves with northwest path that affects the area was nesting of WAVEWATCH III and SWAN models, and the method for treating tion of the complicated islands with sea chart data was used in the high resolution Analysis shows that the influence of typhoon on the areas to the southeast, northeast, the Zhoushan Islands are different; the distribution of the typhoon wave characteristics he distribution of islands in this sea area and water depth etc; and the local features at area are evident.
