| 摘 要： | 以CCMP（Cross—Calibrated,Multi—Platfoml）风场为驱动场，分别驱动目前国际先进的第3代海浪模式ww3（WAVEWATCH—III）、SWAN（Simulating WAves Nearshore），对2010年9月发生在东中国海的台风“圆规”所致的台风浪进行数值模拟，就台风浪的特征进行分析，并对比分析两个海浪模式的模拟效果。结果表明：1）以CCMP风场分别驱动WW3、SWAN海浪模式，可以较好地模拟发生在东中国海的台风浪，风向与波向保持了大体一致，波高与风速的分布特征保持了很好的一致性；2）综合相关系数、偏差、均方根误差、平均绝对误差来看，两个模式模拟的有效波高（SWH—Significant Wdve Height）都具有较高精度，SWAN模拟的SWH略低于观测值，WW3模拟的SWH与观测值更为接近；3）台风浪可给琉球群岛海域带来5m左右的大浪，台风浪进入东海后，波高、风速都有一定程度的增加，当台风沿西北路径穿越朝鲜半岛时，受到半岛地形的巨大影响，风速和波高都明显降低。

| Abstract: | In this thesis, the wave field caused by the typhoon ＂KOMPASU＂ was simulated by using WW3 （WAVEWATCH- hi） wave model and SWAN （Simulating WAves Nearshore） wave model, with CCMP （Cross-Calibrated, Multi-Platform） wind field as the driving field. By analyzing the characteristic of typhoon waves and contrasting the simulation ability of the two wave models, a reference for preventing disasters, reducing damages and studying typhoon waves will be provided. Then the simulation results were contrasted. Results show- that： 1） Both WW3 and SWAN wave model can well simulate the typhoon wave field happened on the East China Sea. The changing of wave directions was accordant with that of winds . The significant wave height （SWI） has good accordance with sea surface wind speed. 2） From correlation coefficient, Bias, RMSE, MAE, the SWH of SWAN and WW3 have high precision. The SVH of SWAN is slightly lower than the observation wave height; the SWH of WW3 is closer to the observation wave height. 3） Typhoon can cause big wave as high as 5m around Ryukyu Islands. After typhoon wave enters the East China Sea, wave height and wind speed increase to some extent. When the typhoon passes through the Korean peninsula along the northwest route, getting a huge influence of peninsula topography, both the wind speed and wave height reduces obviously. |
