为了获得比传统波浪统计方法更准确的结果，采用第三代深海波浪模型WAVEWATCH III(WW3)对西北太平洋海浪场进行模拟。该模型由QSCAT/NCEP混合风驱动，实现了更可靠的波浪参数统计分析方法。从以下几个方面验证了模拟结果的准确性：首先，将QSCAT/NCEP风数据与观测数据进行了比较。其次，根据最新的测深图对西北太平洋的测深数据进行数字化改造，最后将模拟结果与观测数据进行比较，相关系数大于0.9。此外，建立了集数据分析和图形显示于一体的后处理系统，并对计算结果的时间和空间分布进行了综合评价。结果可直接应用于科学实验、海军和海洋工程。
In order to obtain more accurate results than the traditional method of wave statistics,the third-generation deep-sea wave model WAVEWATCH III(WW3) is applied to simulate the sea wave field of the Northwest Pacific.The model is driven by the QSCAT/NCEP blended winds.Then a more reliable statistical analysis method of wave parameters is implemented.The accuracy of the simulation results is verified by the following facets: Firstly,the QSCAT/NCEP wind data have been compared with the observational data.Secondly,the bathymetry of the Northwest Pacific Ocean is digitally transformed from the latest bathymetric charts.At last,the comparison between the simulation results and observation data indicates that the correlation coefficient is greater than 0.9.In addition,a post-processor system which integrates data analysis and graphic display is established.Furthermore,a comprehensive evaluation is presented after analyzing the time and spatial distribution of computational results.The results can be directly applied to the scientific experiments,naval and ocean engineering.
