| Outline of Final Research Achievements |
Considering the fact that the flash rate and charge structure in convective cells, change drastically within a few minutes, the temporal resolutions of previous radar observations (typically 5 min) were insufficient for establishing relationship between the updraft and lightning activity. Weather radar observations with high temporal resolution are required for a more comprehensive description of the relationship between thunderstorm electrification and storm kinetics. In the present study, we observe thunderstorms by using a X-band phased array weather radar, C-band polarimetric radar, and a 3‐D lightning mapper, called the Broadband Observation network for Lightning and Thunderstorm (BOLT), in Kanto region, Japan. The multiple‐radar analysis enables us to understand, in detail, the precipitation and charge structures.

| Academic Significance and Societal Importance of the Research Achievements |
本研究が進むことにより、電荷構造と密接に関連している発雷機構や雷放電進展プロセスの解明につながり、将来的な雷防災に貢献する。さらには雷放電や雷放電とかかわりの深い顕著現象（竜巻、降雹）の発生予測精度の向上につながる。
