Lightning and Thunderstorm Observation with High Resolution

Abstract

A high resolution radar has been newly developed and tested recently in order to observe the fine structure of thunderstorm. Lightning location system which determines the sources of the VHF impulses emitted from lightning also implemented near the radar site. The initial observation shows that a ground flash initiated near 0 degree level just above the thunderstorm core and propagated to the ground along the edges of the thunderstorm, suggesting that the simultaneous observation with lightning and high resolution radar system will be novel tool for lightning research and prediction.
