Abstract: This study evaluated wind speed and simulated vertical wind by using the WRF model, which designed six sets of simulations with different physical parameterizations at the mountain wind station of Jiangxi province from July 2016 to January 2017. Results showed that MRF boundary layer scheme, the microphysical scheme of WSM3 and Noah landsurface scheme were the three best reasonable parameterization scheme simulation. The optimized parameterization scheme performed well in simulating the wind speed for the whole year, the daily variation trend of wind speed and the distribution of wind speed were consistent with the measured. The peak distribution and the probability of simulated wind speed were overestimated due to the lack of accurate topographic resolution of model. The simulate wind direction statistics of the optimized parameterization scheme and the actual recorded wind direction statistics were in good agreement, and the wind direction frequency distribution was similar
