【摘要】：构建CCMP再分析风场与Holland经验台风风场的叠加风场作为海浪的驱动风场,建立SWAN自嵌套模型对影响江苏沿海的典型台风"梅花"引起的台风浪过程进行模拟。在得出风场叠加方式的基础上,设计3种订正系数方案及3种权重系数方案共9种风场构建方案,分别对东中国海进行台风浪模拟并结合Jason-1卫星高度计观测的有效波高数据进行比较分析,实验结果显示各方案有效波高的相对误差最大可相差3%。选取最佳方案的模拟结果为嵌套区域提供波谱边界条件,对嵌套区域的模拟结果表明:模拟值与浮标实测资料吻合较好;台风经过江苏沿海期间,近岸海域最大波高可达5~6 m,中北部海域波浪以涌浪为主,而南部海域则以风浪为主。
[Abstract]:The CCMP reanalysis wind field and the Holland empirical typhoon wind field are constructed as the driving wind field of the waves, and the SWAN self-nested model is established to simulate the typhoon wave process caused by typical typhoon "Meihua" in the coastal area of Jiangsu Province. On the basis of the wind field superposition mode, three revised coefficient schemes and three weight coefficient schemes are designed, and nine wind field construction schemes are designed. The typhoon wave simulation in the East China Sea and the data of effective wave height observed by Jason-1 satellite altimeter are compared and analyzed respectively. The experimental results show that the maximum relative error of the effective wave height of each scheme can be 3. The simulation results of the optimal scheme provide spectral boundary conditions for the nested regions. The simulation results of the nested regions show that the simulated values are in good agreement with the measured data of the buoys. In the coastal area of Jiangsu Province, the maximum wave height in the coastal waters of Jiangsu Province can reach 5 ~ 6 m, the waves in the central and northern sea areas are mainly surges, while in the southern waters, the waves are mainly wind waves.
