| Outline of Final Research Achievements |
We proposed a new method for lightning imaging using the latest adaptive sensing technique. We confirmed that the new method estimates lightning current distribution more effectively than the convectional method based on simulation and data analysis of lightning discharges. Furthermore, we performed observation data analysis for understanding relationship between lightning activity and thunderstorm kinetics. In the analysis, we showed an increase of lightning activity when updraft in the thunderstorm became strong. Since strong updraft sometimes cases local severe rains, these results contribute to development of forecasting of local severe rains.
