摘　　要：基于第三代海浪数值预报模式WAVEWATCH III(v3.14),构建了全球区域海浪数值预报系统,采用1999年9月—2009年7月的Quik SCAT/NCEP混合风场作为驱动场,对模式进行了10a的积分。利用NDBC浮标数据及Jason-1卫星高度计资料对模式模拟结果进行了检验,结果表明:模式对全球海浪模拟效果较好。通过对模式误差的分析,为后续开展全球海浪同化工作中背景误差协方差矩阵的构建及集合样本的选取提供了依据。Based on the third-generation wind-wave model called WAVEWATCH Ⅲ,the global ocean wave numer-ical prediction system is established. A 10-year global experiment is designed using QuikSCAT/NCEP blended wind field from September 1999 to July 2009 as atmospheric forcing field. By comparing with NDBC buoy data and Jason-1 satellite altimeter ocean wave data, the results indicate that WAVEWATCH Ⅲ works well in the simulation of global ocean wave. Through the analysis of the model error, it also provides effective model error which is a reliable basis in building background error covariance matrix and choosing ensemble members in the global ocean wave data assimilation later.
