Abstract

In this paper, an investigation into cloud-to-ground (CG) lightning activity data from the year of 2005 to 2014 collected by lightning location system (LLS) of Shanghai district is shown, including the ground flash density (GFD) maps of Shanghai City and comparison of annual lightning days (LDs) with thunderstorm days (TDs) collected by the Shanghai Meteorological Agency (SMA). At last, the peak current cumulative distribution of CG flashes is also discussed, which is suggested to be used in the design of transmission line lightning-proof for the State Grid Shanghai Municipal Electric Power Company.
