Long Term Variation Of The Lightning Flash Characteristics In The Southeastern Brazil:1988-1995

The long-term variation of the cloud-to-ground lightning flash density in terms of its geographical, monthly and<br>diurnal distribution is presented, based on the longest lightning data set ever obtained in the tropics. The<br>results are based on 12.8 millions cloud-to-ground lightning flashes recorded in the southeastern Brazil from<br>1988 to 1995 with a lightning network consisting of four LPATS sensors located in Minas Gerais. They should be<br>considered as reference for future studies in this region.
