Outline of Final Research Achievements

Knowledge of the electric charge of precipitation particles in thunderclouds is essential for understanding the mechanism of lightning generation. However, there has been no low-cost, easy-to-use meteorological observation device to measure it. Therefore, in this study, we developed a new, compact, lightweight, low-cost, and user-friendly sensor (EC sensor) equipped on the 400 MHz radiosonde. This new EC sensor can be attached to a balloon and released into a thunderstorm cloud, and the amount of positive and negative charge and the number of particles detected by the sensor every second can be monitored on the ground in real time. Although the COVID-19 epidemic prevented sufficient test flights, the new charge sonde was completed through prototype design, ground testing, and the development of data recording software.

Academic Significance and Societal Importance of the Research Achievements

雷予測は数値モデルによるところが大きく、近年の数値モデルの発展はすばらしいものがあるものの、その数値モデルの答え合わせ(検証)となるべく観測データがないことが雷予測を停滞させている一つの要因である。本研究で開発した新しい電荷ゾンデは雷雲内の降水粒子の帯電電荷を知ることができるため、この雷予測モデルの答え合わせに直接的に貢献し、それにより雷発生のメカニズム解明だけでなく、予測精度の向上が期待される。豪雨メカニズムと雷は密接に関連していることから、近い将来この電荷ゾンデが豪雨観測に投入されることが望まれる。
