基于WRF与MIKE-SW模式的连云港海域台风浪数值模拟

Numerical simulation on typhoon waves in Lianyungang sea area by WRF and MIKE-SW

为准确模拟台风过境期间连云港海域波浪场分布,将大气模式WRF模拟的海面10 m风速作为波浪模式MIKESW的驱动风场,再现0713号台风过境期间波浪变化过程。数模与实测资料验证结果表明WRF模式成功复演了韦帕台风移动、风速变化过程,考虑风暴潮增水效应的MIKE-SW台风浪模型能够较好地反映台风过境期间海浪成长过程。

To accurately simulate the wave field distribution of Lianyungang sea area during typhoon transit period, we use the atmospheric model WRF to simulate the 10 meters wind speed above the sea level. The wave mode MIKE-SW driven by the wind field is used to simulate the 0713 typhoon waves growing process. The comparisons between the simulated and measured values show that the WRF model successfully simulates the typhoon Wipha＇s moving and changing process. Considering the effect of storm surge water＇s increase, the MIKE-SW model can reflect typhoon wave＇s growing process during the typhoon transit in Lianyungang sea area.
