Abstract A coupled WRF/Noah/UCM model was employed to investigate the change of the underlying surface and simulate the impacts of urban expansion in the Pearl River Delta (PRD) on regional meteorological conditions in winter (January) and summer (July) in the future. The land use types were updated in the WRF model based on "the full scale strategic planning of the Pearl River Delta for the period of 2014~2020". In WRF model simulation, the GlobCover 2009 (GLC2009) underlying surface data were used in the control experiment, while the updated one was employed in the sensitivity experiment. Several conclusions can be drawn from this study:significant changes of surface energy balance were observed due to the change of the underlying surface types that are caused by urban expansion; urban temperatures in the PRD region increase by 0.75℃ and 1.20℃ respectively in January and in July; relative humidity decrease by 2.61% and by 6.88% respectively in January and in July; urban heat island effect will be strengthened; the temperature difference between urban areas and rural areas increased by 0.21℃ and by 0.41℃ respectively in January and in July; the superimposing effect of thermal circulation and the large-scale circulation resultd in decrease of the wind speed by 0.11m/s in January and increase by 0.11m/s in July. In addition, changes near the surface can influence the whole boundary layer and increase the boundary layer height.
