Abstract

A series of laboratory experiments has been conducted to investigate the initiating and guiding effects of laser plasma channel on electrical discharge. It was confirmed that the plasma channels have strong guiding effects and reduce the required electrical field strength for electrical discharges to occur. A field experimental site targeting natural lightning is being prepared to develop the thunder storm monitoring system and to test the laser and optical systems against various weather conditions. The results from the laboratory experiments and laser transmission in snowy conditions as well as attempt of initiating electrical leader will be discussed.
