Analyzing relationship between the atmospheric state change and lightning activity in autumn season

Abstract

An analysis between the atmospheric state change and lightning discharges in the autumn (from Sep to Nov. 2011 and 2016) seasons in Japan is presented in this paper. In evaluating the number of lightning activities, we calculated SSI which is used to predict thunderstorms. We confirmed that the modified SSI for the winter season can be effective for evaluating the lighting activities in the autumn season, meaning that the lighting discharges in this season tend to be affected by the low-level atmospheric state condition.
