Abstract: The meso-scale urban atmospheric boundary layer model of Peking University, with three-dimensional complex topography, was improved by introducing the second generation land-surface model, which paid more attention to the effect of vegetable coverage when computing land-surface water balance. The improved model was used to simulate temperature, wind and humidity fields over Beijing in summer. It is found that the model can provide acceptable results compared with observations. The simulation results are important to understand the local climate over Beijing area and the feature of diffusion of pollutants, and are helpful for making practical urban design.
