In order to evaluate the performance of boundary layer (BL) schemes on wind prediction in western Inner Mongolia

seven hindcasting simulation experiments are conducted with different boundary layer parameterization configurations in Weather Research Forecast(WRF). Observations from 70 national stations and 18 wind towers are used as the reference of the evaluations. The results are shown as follows: The variability of wind field can be captured in the numerical simulations. There exists a slightly clockwise deviation in the directions of 10 m and 70 m wind fields in all simulation experiments. The performance of BL schemes on 3~15 m/s wind field is superior to those on 15~25 m/s

while poor simulation results are presented on 0~5 m/s wind field. The diurnal variation of wind speed and direction can be described in all BL schemes

as corroborated by an increasing wind speed and a clockwise rotating wind direction during the daytime and a decreasing wind speed and a counterclockwise rotating wind direction during the nocturnal time. The differences of BL scheme experiments on 10 m wind field are more obvious than those on 70 m wind field

with a larger overestimation in the amplitude of wind. The YSU works best at 10 m wind speed

and ACM2 performs better at 70 m wind speed. The TEMF

YSU and ACM2 are more effective for prediction of wind shear. The atmospheric stability is of vital importance for the simulation of low-level wind field.
