Evaluation of CMIP6 models for rainfall simulation in Central Eastern Africa using extreme precipitation indices

Accurate simulation of extreme precipitation is crucial for understanding climate variability and informing adaptation techniques in Central Eastern Africa, a region with complex climatic and topographic situations. This study evaluates the performance of 19 CMIP6 models in simulating precipitation and its extremes using five indices: PRCPTOT, CDD, R95p, R20mm, and SDII-based on their spatial and temporal variability during 1981–2014. Using Taylor diagrams for spatial patterns and interannual va
