The objective of this work is to study the spatial and temporal dynamics of rainfall across the country in order to guide policy measures for major disaster management. The methodology is based on the mapping of statistical metrics calculated on time series of annual cumulated rainfall from CHIRPS data and the annual number of rainy days estimated by the ANAM over the period 1991-2020. The results indicate an average variability in rainfall over the 1991-2020 normal. The persistence of drought in the Far West is accompanied by a loss of rainfall. The approach based on the two data sources presents similar information for the assessment of rainfall variability, complementary for the estimated rainfall trend areas, and the frequency of drought and contradictory for assessing the frequency of wet years.</p>}, number={1}, journal={American Scientific Research Journal for Engineering, Technology, and Sciences}, author={Yélézouomin Stéphane Corentin Some and Alimata Zorom and Wièmè Some}, year={2022}, month={Oct.}, pages={52–62} }
