Abstract: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 com-pared 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 CC-MPv2 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.
