| Outline of Final Research Achievements |
In this study we have developed three types of systems for lightning research. The first system is for measuring the lightning attachment process and it has the features of high time resolution, wide dynamic range, high sensitivity and wide horizontal view. The second system is for locating lightning discharges in 3D. The third system is the sensor for measuing the 3D electric field distribution of thunderstorms. Using these systems, we have carried out lightning observation experiments and obtained many lightning data. After analyzing the data, we have revealed several lightning discharge processes. We have also understood the relation between the thunderstorm electric charge stucture and the lightning intensity. We have pointed out the possibility for predicting the lightning intensity.
