Relationships between lightning and insolation during monsoon season in Benin

Abstract

This work documents for the first time in Benin, the relationship between electrical activity of storms and insolation data used were collected for five months by the LINET network and by a Campbell synoptic station of Natitingou (North-West Benin). A linear regression model was used on a sample made from days with strong electrical activity. The main results obtained present a fairly good correlation between insolation and lightning intensity. The highest value (0.65) of the correlation coefficient is obtained with the cloud threshold within 15 km radius around the synoptic station of Natitingou.
