WRF动力降尺度方法在广东近海风资源评估中的适用性分析
Applicability of WRF dynamic downscaling method in the assessment of wind resources in offshore Guangdong
摘要
Abstract
This study employs the WRF model(Weather Research and Forecasting Model,WRF)to dynamically downscale ERA5(ECMWF Reanalysis v5)reanalysis data,yielding high-resolution WRF data.The applicability of the WRF high-resolution data and ERA5 reanalysis data is assessed using observation data of 3 wind towers.Results show that wind speeds derived from the WRF exhibit closer agreement with observations,whereas ERA5 tends to underestimate wind speeds.Both WRF and ERA5 demonstrate comparable capabilities in reproducing the dominant wind directions in offshore Guangdong,reflecting these directions as well.The correlation coefficient between WRF(ERA5)and the observations exceeds the 99%confidence level.Compared with ERA5,the performance of Weibull fitting using WRF data is closer to the observations.Consequently,WRF data are more suitable than ERA5 for assessing wind energy resources in offshore Guangdong.The spatial distribution of wind resources,as derived from WRF data,reveals substantial wind power densities(>200 W/m²),a high frequency of effective wind speeds(>0.88).These factors,combined with the presence of one or two dominant wind directions,collectively indicate favorable conditions for wind energy development in offshore Guangdong.关键词
