摘要
以1991—2011年风场数据为驱动,运用第3代波浪模型SWAN对江苏海域的波浪分布特征进行了模拟研究。首先运用基于浅水方程的Delft3D-flow模块对江苏海域的潮波进行模拟,给波浪模型提供一个准确的边界条件;其次运用SWAN模型对江苏海域的波浪进行模拟并与观测值进行比较;最后对江苏海域的波浪分布特征进行研究。结果表明:江苏海域年平均波高由南往北依次递减,年平均最大值为1.5 m左右,强浪向为NE向,四季中冬季的平均波浪最大,春秋次之,夏季最小。
This paper studies the wave distribution of Jiangsu sea with SWAN wave model, which was driven by the wind filed from 1991 to 2011. Firstly, the tidal level is simulated by Delft 3D flow model. Then, the wave parameters of Jiangsu sea are computed. Lastly, the wave condition of Jiangsu sea area is analyzed. The result shows that： the annual average wave height becomes smaller from southeast to northwest. The largest annually average wave height is around 1.5 m. Most waves come from direction NE and SE, and the strong wave direction is NE. The wave height in winter is larger than that in other seasons.
