摘要
北海银滩海域实测波浪资料缺乏,为了获取银滩附近海域的波浪数据,以便对银滩水动力条件进行分析,利用WRF（全球气候模型）对NCEP（美国环境预测中心）的CFSR（气候预测系统再分析）资料进行再分析,得到北海区域高空间分辨率的10 m高度风场,并建立潮流模型以计算北海海域潮流场,进一步利用风场、潮流场成果建立MIKE 21 SW波浪模型对北海海域波浪场进行模拟计算及分析。结果表明：模型计算成果合理,可为银滩海域波浪分析提供有效的手段;北海银滩附近全年波浪以南向浪为主且趋于与银滩滩面垂直,全年浪高多为0.2-0.5 m,波浪周期一般为2-4 s。
In order to obtain the wave data to analyze the hydrodynamic condition of sea area near Silver Beach which lacked observed wave data, the CFSR data of NCEP are reanalyzed based on the WRF global climate model to obtain the 10 m-height wind field with high spatial resolution, and a tide current model is established to obtain the water current field. Based on the simulation results of wind and current field, a MIKE 21 SW wave model is established to simulate and calculate the wave field in Beihai sea area. The results show that the established wave model can be effectively applied to analyze the wave field in sea area near Silver Beach where southbound waves prevail; that the waves tend to be vertical to the beach;that the wave height is mostly between 0. 2 and 0. 5 m, and that the wave period is commonly between 2 and 4 s in a year.
