| 摘要: |
| 采用多重嵌套中尺度大气数值模式提供的风场,在考虑了波-流相互作用等主要物理过程的基础上,应用最新版本的第三代海浪模式SWAN对Winnie(1997)引起的台风浪进行了模拟,将模拟的有效波高与TOPEX/POSEIDON和ERS-2卫星高度计资料作了详细的对比分析,并分析了台风浪要素的分布特征。结果表明,SWAN在模拟较大尺度的海区时也能得到较好的模拟效果,能较好地再现海浪的发展过程和合理地反映台风浪的分布。 |

| Abstract: |
| In this paper,the wind field provided by a meso-scale tropical cyclone numerical model is employed.When main physical processes,including wave-current interactions,are considered,the latest version of the third generation wave model SWAN is applied to simulate the typhoon wave generated by Typhoon Winnie(1997).The model results are compared with the TOPEX/POSEIDON and ERS-2 satellite altimeter data and analyzed in details.Then the distribution of wave fields are analyzed,with the results showing that applying SWAN to simulate large-scale domain can also fairly reproduce the observed features of waves and preferably reflect the distribution of typhoon waves. |
