Abstract

The selection of parameterization schemes in the WRF (weather research and forecasting) model is closely related to the simulation results of near-surface wind field. In order to ensure the accuracy of wind field simulation in different terrains in northern Xinjiang, WRF model was adopts to investigate the effects of four types of parameterization schemes (boundary layer, microphysics, land-surface, near-surface layer) and subgrid-scale terrain parameterization schemes on wind field simulation. The results indicate that: each group of experiments can simulate the change trend of wind speed. RUC (rapid update cycle) of land-surface schemes and Lin (Purdue Lin) microphysics scheme have better simulation results in plain area, while Noah land-surface scheme and WSM6 (WRF single moment 6 class) of microphysics schemes have better simulation results for mountainous terrain. For both the plain and valley terrains, the subgrid topographic terrain schemes can provide a better correction for the simulation.
