摘　　要：利用Jason-1和Jason-2卫星高度计资料对WAVEWATCHⅢ模式模拟的2009—2011年中国东部海域模拟海浪场进行全海区逐年检验、分海区检验和全海区逐月检验,并进行了模拟波高与实测波高的差值概率密度分析。结果表明:虽然WAVEWATCHⅢ模式能较好地模拟中国东部海域海浪的分布和演变,全海区模拟波高平均相对误差小于18.5%,但模式对波高的模拟精度存在空间性和季节性差异。东海模拟误差小,相关系数高;黄、渤海模拟波高偏小,渤海误差较大。模拟误差春、夏大,秋、冬小。模拟波高与实测波高相比,冬季略偏大,春、夏季偏小。The satellite altimeter data derived from Jason-1 and Jason-2 is used to validate the wave field simulated by WAVEWATCH Ⅲ from 2009 to 2011 in the East China Sea, which includes the yearly validation, regional validation and monthly validation . The probability density of difference between simulated waves and measured values are analyzed. The result shows that the WAVEWATCH Ⅲ model has a better simulation effect on the distribution and evolution of the waves in the East China Sea with the mean relative error of wave height less than 18.5%. The simulation precision has a spatial difference and seasonal variation. The simulated wave in the East Sea has a smaller error and a higher correlation coefficient, while the simulated wave in the Bohai Sea has a larger error. The simulated wave is smaller than the measured value in the Bohai Sea and Yellow Sea. The simulated error is larger in spring and summer while smaller in autumn and winter. The simulated wave is larger than the measured value in winter and smaller in spring and summer.
