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 WAVEWATCH III (v3.14), a third-generation ocean wave forecasting model, a global regional ocean wave forecasting system was constructed. The Quik SCAT / NCEP hybrid wind field from September 1999 to July 2009 was used as a driving field to model The score of 10a. The NDBC buoy data and the Jason-1 satellite altimetry data were used to test the model simulation results. The results show that the model has a good effect on global ocean wave simulation. The analysis of the model error provides the basis for the construction of the background error covariance matrix and the collection of samples in the global wave assimilation.
