Research Abstract

In this research project, two observation system was developed, and successfully operated for thunderstorm electrification process studies. One observation system is an electric field observation system which measures electric field changes at LF band at multipoint, and another system is broad band radar observation network. In the lightning observation system, the time of arrival technique is applied to locate the sources of pulses emitted from lightning process. The height histogram of the initia breakdown process shows the tripole electrical structure of the thunderstorm on the assumption that the negative leader toward the positively charged region and the positive leader toward the negatively charged region produce the impulses at LF band. The relationship with the radar reflectivity factor measured by the broad band radar and phased array radar network was also discussed.
