摘　　要：全球闪电活动与气候变化关系的研究正受到越来越多的重视,该文从卫星上观测到的全球闪电活动、闪电活动和全球电路对温度的响应,闪电和对流层上部水汽的联系,闪电和NOx等几方面进行了阐述,指出了闪电活动在气候变化研究中的重要性。同时,文中还对影响闪电活动和起电过程的热力动力作用以及气溶胶的作用等进行了分析。The relationship between global lightning activity and climate change has been paid more and more attention. Areas treated in this paper include the global lightning activity observed from the satellite, the dependence of lightning activity and global circuit on temperature, the connection between lightning and upper troposphere water vapor, and lightning and NOx. The importance of lightning for climate studies has been pointed. Meanwhile, the role of aerosol and thermodynamic electrification processes and lightning activity are discussed.
