A Study About The Occurrence Of Days With High Activity Of Cloud-To-Ground Lightning Flashes In The Southeastern Brazil In The Years 1992 To 1994

The occurrence of days with high activity of cloud-to-ground lightning flashes in the southeastern Brazil in the<br>years 1992 to 1994 was investigated. The high activity days were arbitrarily defined as those with more than<br>20,000 cloud-to-ground flashes. The meteorological conditions and flash characteristics during these days were<br>determined. The lightning data were obtained through a lightning location system (LPATS), and the flash<br>characteristic studied were the polarity, the peak current intensity and the diurnal distribution.
