摘要
基于欧洲中期天气预报中心提供的第五代再分析数据集中较高分辨率的波浪数据,计算分析了2017年中国东部大陆架海域涌浪和混合浪波能流的时空分布特征,研究了该海域波能流的传递特性。结果表明:研究海域的混合浪、涌浪波能流都以流向外海为主,波能流传递方向基本一致,在数值上涌浪波能流明显小于混合浪波能流,中国东部大陆架海域产生的较大波能流由各个海峡流向外海;研究海域混合浪波能流分布具有明显的季节性,秋冬季节较大,春夏季节较小,大值区主要集中在吐噶喇海峡、奄美海峡、宫古海峡和台湾海峡附近;涌浪波能流空间分布的季节差异相对较小,大值位于奄美海峡、宫古海峡和与那国海峡附近。
Based on the higher resolution wave data in the fifth-generation reanalysis dataset provided by the European Centre for Medium-Range Weather Forecasts,the temporal and spatial distribution characteristics of surge and mixed wave energy flux in eastern China Sea area in 2017 were calculated and analyzed,and the transmission characteristics of wave energy flux in this area were studied as well in this paper.The results show that the mixed wave and swell wave energy flux in the study area mainly flow to the open sea,and the transfer direction of wave energy flux is basically the same.The energy flux of swell wave is larger than that of mixed wave in number.Generally speaking,there is a large wave energy current in the eastern part of China’s continental shelf,which flows from each channel to the open sea.The distribution of mixed wave energy flux in the study area has obvious seasonality,which is larger in autumn and winter and smaller in spring and summer,and the largest value is located near the Tokara,Amami,Miyako and Taiwan Strait.
