The incorporated model is evaluated by simulation results of two different building aerodynamical scheme in southeast region of Beijing area, which are building drag scheme and aerodynamical urban canopy scheme. The conclusions are drawn by the comparisons between the simulation results of the wind speed and the observations of the automatic weather stations in the urban areas: the simulated results of incorporated model are more in reasonable agreement with the observations than that of building drag scheme, and the diurnal trend of that is more agreement with observations.
