| 摘 要： | 下垫面所具有的非均匀性特征会对强对流天气产生很大的影响作用，这种影响主要通过改变边界层热力、动力过程及地气之间的热量输送与水分循环，进而改变大气的温湿结构和垂直运动来实现。该文主要介绍利用陆面模式研究下垫面特征的成果，并且讨论不同类型下垫面，包括自然形成的地表特征、植被覆盖及城市化作用等对强对流天气影响的研究成果，重点分析中国地区,就陆面模式的模拟方法和下垫面变化时所产生的问题进行深入的探讨。

| Abstract: | 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. |

| Keywords: | underlying surface severe convection land surface mode vegetation cover urbanization |
