基于WRF-SWAN模式的韦帕台风波浪场模拟

Numerical simulation of WIPHA typhoon waves using WRF-SWAN model

为获取更为准确的台风过程波浪模拟结果,将中尺度大气模式WRFD海面以上10 m处风速资料作为驱动风场提供给第三代海浪模式SWAN进行波浪计算,模拟了0713号"韦帕"台风的波浪场过程。模拟和实测资料比较结果表明WRF模式能较好地模拟韦帕台风过程,给SWAN模型提供高精度风场资料,WRF-SWAN模式能够较好模拟韦帕台风过程中海浪的演化和传播。

In order to get better wave simulation results,the wind data at 10 m above water surface,which were the results of the mesoscale atmospheric model WRF,were taken as driving wind field of the third-generation wave model SWAN,and the 0713 WIPHA typhoon wave was simulated.The comparisons between simulated and measured results show that the WRF model can simulate the wind field well during the WIPHA typhoon process and provide the SWAN model with high resolution wind data.The WRF-SWAN model can simulate the evolution of the typhoon wave during the process of WIPHA satisfactorily.
