[MIS05-P01] Study on monitoring of thunderstorm activity based on multiple electrostatic measurement
Keywords:thunderstorm, electrostatic field, sensor network
Ground-based measurement of electrostatic field has been also considered as an efficient way to detect electrification in thundercloud and monitor development of severe storm. In preceding studies, multiple electrostatic measurement has been examined to estimate charge amount in cloud. One of the difficulties for those studies is to understand correlation between electrostatic field on ground and charges in horizontally extended thunderstorm. In this study, methodology for quantitative evaluation of charge amount in cloud is developed. We newly construct multipoint electrostatic sensor network in Tochigi, Japan. In this region, isolated thunderstorm whose horizontal scale is about 10 km occurs. By analyzing Isolated thunderstorm, we can simplify the correlation between ground-based electrostatic field and charge in cloud. In this presentation, initial result of electrostatic measurement with multiple sensors is summarized.
