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 light山ng and upper troposphere water vapor .and lightning and NOx.  The importance of light-
ning for climate studies has been pointed. Meanwhile.the role of aerosol and thermo勿namic electrification processes and lightning ac-
tivity are discussed.
