The microphysical properties and boundary layer characteristics of three icing processes that took place at Enshi radar station in the winter of 2008 and 2009 was simulated by using the Weather Research and Forecasting(WRF) mesoscale model coupled with the Thompson microphysical scheme, and the results were compared with the observational data.The results showed that the simulations could well reflect the appearance of inversion layer over the radar station.The mean absolute errors of mass concentrations of cloud water and median volume diameter of cloud/fog droplets between simulations and observations were 10^-2 g·m^-3 and 3.8 μm, respectively.There was a high center whose mass concentration was 0.3 g·m^-3 over the radar station, and it moved to the ground gradually, bringing sufficient droplets and precipitation to the ice accretion processes.
