摘要： 基于第三代海浪(谱)模式WAVEWATCH Ⅲ,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0.4~1.2 m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WAVEWATCH Ⅲ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。 关键词： WAVEWATCH Ⅲ;  NCEP/QuikSCAT混合风场;  有效波高;  浮标     Abstract: Wave numerical simulations of East China Sea,Eastern Pacific and central Pacific waters near Hawaii are carried out based on third-generation wave model WAVEWATCH Ⅲ,using NCEP/QuikSCAT wind field as model mixed input.In East China Sea,it is obtained that significant wave height and the reference value of buoy has a strong correlation coefficient,and the root mean square error of wave height is about 0.5 m by simulation;In the Pacific waters near the east coast and Hawaii,significant wave height values are generally lower than the reference value of buoy,root mean square error of wave height of different months is between 0.4 and 1.2 m,but the simulation of wave height and the reference value of buoy still has strong correlation.The results show that it is feasible that taking advantage of WAVEWATCH Ⅲ combined NCEP/QuikSCAT mixed wind field to simulate the wave height of East China Sea.However,it is still necessary to consider some non-wind factors in simulation of wave height lies at Pacific Ocean and the eastern open deep waters.
