Diurnal and Monthly Variability of Lightning Observation Over West Africa

This study examines in detail lightning activities over West Africa using the worldwide location network (WWLLN). The Worldwide Lightning Location Network (WWLLN; operated by University of Washington) is a developing, experimental detection increasingly used for applications. In Africa, there are many studies on diurnal process activity at regional level, but shortage literature examining variation observation this region. Therefore main objective to examine presenting an evaluation WWLLN data as ground truth improve knowledge ground-based system. For study, variability flash counts (frequency) was measured three climatic sub-region (Guinea, Savannah and Sahel) sub-regions line graph plot time. All regions exhibit strong variation, with peaking late afternoon between 1500 1700 WAT decreased morning 0900 1100 WAT. amplitude varies throughout Africa.
