摘　　要：CCMPv2、ERA5、CFSR&CFSv2再分析风场因时空分辨率较高,在波浪、潮汐模拟中应用广泛,但其数据质量在空间上不恒定,对于中国海,受限于实测资料数量,目前尚未有学者对上述风场在其范围内的质量进行广泛、详细的对比。本文提取1998—2014年的ICOADS数据,利用风速计高度将其统一修正至10 m高度处,对三种风场在中国海及各海域的质量从风速和风向角度分别进行了对比,结果表明:(1)CFSR&CFSv2再分析风速、CCMPv2再分析风向在中国海整体与实测数据一致性最高;(2)同一海域最优风速、风向大都不出现在同一风场:再分析风速中,三巴海峡周边、西太平洋、南海北部以ERA5为优,其他海域最优均为CFSR&CFSv2;再分析风向中,渤海、福建及台湾沿海、北部湾以CFSR&CFSv2为优,其他海域最优均为CCMPv2。CCMPv2,ERA5 and CFSR&CFSv2 are widely used in numerical simulation of wave and tide for their higher resolution in spatial and temporal,however the quality of the reanalysis wind field data is not constant in space.For the China Sea,due to the limited number of measured data,yet no scholar conducts extensive and detailed comparison of wind field data quality within the scope.In this paper,we extract ICOADS measured data from 1998 to 2014 and correct them to 10 meters height uniformly by utilizing anemometer height.Afterwards,the qualities of the three kinds of wind field data are compared firstly from the angle of wind speed and direction within China sea and different sea areas of it,the results show that:(1)The reanalysis wind speed and direction data from CFSR&CFSv2 and CCMPv2 respectively are consistent with measured data best in China Sea;(2)The optimal wind speed and direction data in the specific sea area mostly do not appear in the same wind field.From the angle of wind speed,ERA5 is optimal in area around the Sanba strait,the western Pacific and the northern Part of the South China Sea,and the optimal wind field in other sea areas is CFSR&CFSv2.From the angle of wind direction,CFSR&CFSv2 is optimal for the Bohai Sea,sea area around Fujian and Taiwan and Beibu Gulf respectively,and the optimal wind field in other sea areas is CCMPv2.
