The inhomogeneous characteristics of the underlying surface have huge influence on severe convective weather, which achieves mainly through changing the thermal and dynamical processes within the boundary layer and changing the heat transfer and water circulation between air and land, thereby changing the temperature and humidity distribution of the atmosphere, as well as atmospheric vertical motion. The advancements in the researches on the characteristics of the underlying surface with the landsurface process models are described and the achievements in the impacts of different types, including the natural formation of surface features, vegetation and urbanization, of the underlying surface on severe convective weather, are studied, with emphasis in China. The simulation methods of landsurface process models and the problems arising from land surface changing are also discussed.
