Abstract: This study investigates current rainfall trends and the ecological significance of frontal and convectional rains in Sub-Saharan Africa, focusing on Cameroon. By utilizing satellite data and ground station records, it provides a comparative meridional analysis from Kribi in the south to Maroua in the north. The research applies statistical tools such as the Mann-Kendall trend test, coefficient of variation, and Precipitation Concentration Index to assess rainfall variability and intensity. Results indicate an increasing rainfall trend from northern to southern Cameroon and reveal moderate to irregular distribution patterns. These findings highlight the critical need for adaptive strategies in agriculture and water management to enhance resilience against climate variability.
