Abstract:Based on the partial least squares regression (PLS), the near ground wind speed predicted by ZHE～Jiang WRF ADAS Real～time Modeling System(ZJWARMS) is revised and evaluated in each winter form 2013 to 2016 in Zhejiang. The forecast product is used as the independent variable while the corresponding observational data of the automatic weather stations(AWSs) is used as the dependent variable in this research. The results showed that before the correction, absolute error of forecast wind speed is mainly 1.5 m?s～1 on the land, exceeded to 2 m?s～1 in most parts of the coastal and offshore areas, and a few areas up to 3m?s～1. After correction, the absolute error of forecast wind speed is less than 1 m?s～1 on most region of land, while the wind speed absolute error is about 1～1.5 m?s～1 in the eastern coastal of Zhejiang coastal area, and 2 m?s～1 over the ocean. According to the improved percentage of wind speed correction, it is indicated the performance of each local cities is good. In addition to the 49.9% in Zhoushan, the rate of wind speed improvement is more than 50% in other cities. Based on the analysis of the Gale Process in the northeastern coast of Zhejiang in January 20, 2017, it is found that the corrected wind speed is closer to the observed wind speed, especially in the near shore sites.
