ABSTRACT: Extreme rainfall events and their return periods are subjects that pose enormous problems. Extreme rainfall causes a great deal of damage in Africa; loss of life, property damage, etc., has been recorded with each disaster. It is therefore important to understand what characterizes climate variability in order to fully grasp its impacts. The objective here is to determine the maximum rainfall threshold that leads to extreme events in West Africa, particularly in certain African cities, and to be able to provide sustainable solutions to this situation. Using the Pareto distribution method, we can obtain an asymptotic characterization of the distribution of these threshold exceedances and be able to model the problem.
