基于第三代海浪(谱)模式WAVEWATCHⅢ,采用NCEP/QuikSCAT混合风场作为模式输入,进行了东中国海、太平洋东岸以及太平洋中部夏威夷附近海域的海浪数值模拟。在东中国海,模拟有效波高与浮标的参考值有较高的相关系数,波高的均方根误差约为0.5 m;在太平洋东岸和夏威夷附近海域,模拟有效波高比浮标的参考值普遍偏低,不同月份波高的均方根误差在0.4~1.2m之间,但模拟波高与浮标的参考值仍有较强的相关性。结果表明利用WAVEWATCHⅢ结合NCEP/QuikSCAT混合风场模拟东中国海的波高是可行的,但要模拟太平洋中、东部开阔深水海域的波高仍需考虑如涌浪、海流等非风场因素。
Based on the WAVEWATCH III model of the third generation, the NCEP / QuikSCAT mixed wind field is used as the model input to simulate the ocean waves in the waters off the east China Sea, the east coast of the Pacific Ocean and the central Pacific Ocean of Hawaii. In the East China Sea, there is a high correlation coefficient between the simulated effective wave height and the reference value of the buoy, and the root mean square error of the wave height is about 0.5 m. In the waters off the east coast of the Pacific and Hawaii, the reference values of the simulated effective wave buoy are generally biased The root mean square error (RMSE) of wave height at low and different months was between 0.4 and 1.2 m, but there was still a strong correlation between simulated wave height and the reference value of the buoy. The results show that it is feasible to simulate the wave height of the East China Sea using the WAVEWATCH Ⅲ combined with NCEP / QuikSCAT wind field. However, non-wind factors such as surges and currents should be considered in simulating the wave height of the open ocean in the middle and eastern Pacific Ocean.
