Outline of Final Research Achievements |
Observations for lightning channels and related electric field changes were continued for in summer and winter thunderstorm seasons throughout the research period. Simultaneous observation of thunderclouds with high resolution weather radar also performed remote sensing of potential thunderstorm energy from comprehensive analysis of various observation results. An estimation method of neutralized electric charge amount considering lighting channels was proposed and applied instead of the way based on a point charge model. Approximate neutralized charge quantity estimation was realized for cloud-to-cloud lightning flashes including the ones with horizontal very long progression. In the thunderclouds which passed through the observation range of the radar, the convective activity became active immediately before the peak of the lightning activity, and declined from high altitude.
