Peak Current of Negative First Strokes around Kyushu during Convective and Frontal Thunderstorm

Abstract

In this letter we compare the inland and the maritime return-stroke current around Kyushu based on the data obtained by JLDN. It is shown that in case of negative first strokes during the convective thunderstorm, the maritime return-stroke current is higher than the inland stroke current in contrast to the cases of those during frontal thunderstorm.
