|Outline of Final Research Achievements
In order to establish the methodology to make a now cast of thunderstorm, we constructed the ground-based lightning observation networks and investigated the relationship between lightning activity and other meteorological parameters. We completed the construction of the most reliable VLF radio wave network in Southeast Asia and the domestic dense observation network with sensors at every 4 km. We established the methodology of automatic tracking of precipitating and lightning regions, respectively. We found a good correlation between the precipitation area/intensity and lightning frequency. Also we indentified the significant decrease of lightning frequency 10-130 min before down burst. About typhoon activity, we discover the large variation of lightning discharge in charge moment distribution and polarity of the current.
