This paper focuses on two different methods for simulating the impact of urban surface development on monthly averaged meteorological elements in Beijing winter. After analyzing the major weather process and distribution characteristics of month mean meteorological elements in Beijing in January 2012, using WRF/BEP modeling system, the month mean 10 m wind speed, 2 m air temperature and 2 m humidity were simulated by the cases-averaged method and the mean-field method. Then the results of two methods under new and old land use conditions are evaluated against the observation. At last, the analysis of affect caused by urban development and the comparison of two different methods for reflecting this affect are carried out. The results show that: Both methods have good simulation results. Hite rate of air temperature and specific humidity is higher than 70% and the wind speed is more than 60%. The spatial distribution of the characteristics of month-averaged meteorological elements and diurnal variation simulated by two methods are consistent. Urbanization slightly decreases the specific humidity and wind speed in Beijing but increases the air temperature. And the impact of urbanization simulated by two approaches also have the same trend. The cases-averaged method not only reflects the average impact of urban development but also gets the extreme impact of a month. The mean-field method may not get the extreme impact conditions and precipitation simulation.
