HGE01: Ionospheric, magnetospheric and high energy effects of lightning (1)

Monday, August 18  13:40-15:40,  Room #11

Session Chairs: Ningyu Liu, Victor Pasko, Martin Fullekrug

The recent discovery that lightning discharges can cause energetic radiation, relativistic particles, and transient luminous events has marked a profound advance in our understanding of the Earth's atmospheric electrodynamic behavior. This session explores these novel processes and their impact on the near-Earth environment. The session solicits contributions that advance knowledge in the areas of the global atmospheric electric circuit, lightning physics, transient luminous events, energetic radiation, relativistic particles, and their impact on the Earth's upper atmosphere and the magnetosphere. Interdisciplinary studies which emphasize the connection between atmospheric layers and the relation between lightning-related effects and climate change are particularly welcome.
