【摘要】：采用SWAN波浪模式对201415号台风‘海鸥’期间的海浪进行数值模拟,通过与实测数据对比,模拟结果较好。台风风场由圆形对称Jelesnianski-II模型构造,风场结构能够很好的体现出台风过境期间的变化情况。根据台风期间的实测温度数据以及ECMWF海表面温度数据的变化研究海表面温度对台风的响应。研究发现,台风"海鸥"在近海复杂的海洋和地形条件下,台风路径降温范围成不对称分布,最大降温中心出现在路径右侧,降温幅度将近1.5℃。
[Abstract]:The SWAN wave model is used to simulate the waves during typhoon 'Seagull' 201415. By comparing with the measured data, the simulation results are good. The wind field of typhoon is constructed by circular symmetric Jelesnianski-II model. According to the measured temperature data during typhoon and the variation of ECMWF sea surface temperature data, the response of sea surface temperature to typhoon is studied. Under the complex sea and terrain conditions, the temperature drop range of typhoon track is asymmetrical, the maximum cooling center appears on the right side of the track, and the temperature drop range is nearly 1.5 鈩，
