Abstract:Using weather stations and reanalysis data of NCEP/NCAR, NCEP/DOE, CFSR, ERA-Interim and JRA-55, the applicability evaluation of the ground wind velocity over the Bohai Rim Region is conducted in this paper. Results showed as follows: JRA dataset has the highest correlation coefficient with weather stations observations, and ERA dataset has the smallest average root mean square error compared with observations of 23 weather stations. The correlation coefficients are higher in the Shandong and Liaodong Peninsulas than in other areas and also higher in winter half year than in summer half year. Results indicate that the JRA and ERAinterim ground wind velocities have better evaluation applicability over the Bohai Rim Region, and on account of higher horizontal resolution, ERA-interim dataset is selected to use in the strong gale process analysis.
