Assessing the Capabilities of Three Regional Climate Models over CORDEX Africa in Simulating West African Summer Monsoon Precipitation

Abstract: This study evaluates the ability of three Regional Climate Models (RCMs) used in Coordinated Regional Climate Downscaling Experiment (CORDEX) to simulate the characteristics of rainfall pattern during the West Africa Summer Monsoon from 1998 to 2008. The seasonal climatology, annual rainfall cycles, and wind fields of the RCMs output were assessed over three homogenous subregions and validated using precipitation data from eighty-one (81) ground observation stations and TRMM satellite data. Furthermore, the ab… Show more

“…In the literature, model performance evaluations have been achieved by computing statistical indicators, such as the mean bias, the Nash–Sutcliffe Efficiency (NSE), the root‐mean‐square error (RMSE) and the RMSE‐observations standard deviation ratio (RSR) (e.g. Gbobaniyi et al ., ; Zhou et al ., ; Akinsanola et al ., ; McMahon et al ., ). The optimal values of the statistical indicators are: 0.0 for mean bias; 1.0 for NSE; the lower, the better for RMSE; and 0.0 for RSR.…”

“…These models are chosen because many studies (Akinsola, yacouba, Alioune, etc.) [13][14][15] The second are the simulated data. They are the historical and future projections (RCP4.5 and RCP8.5 scenarios) of rainfall and PET.…”

“…These models are chosen because many studies (Akinsola, yacouba, Alioune, etc.) [13][14][15] in the West African region have recognized their ability to reproduce the rainfall regime. Their characteristics are shown in Table 1.…”

“…GCMs are therefore a fundamental tool for understanding climate variations and dynamics. Unlike other climate data sources, such as satellite, radar, and on-site measurement data where only the past and present and climatology represent the key contributions [24][25][26][27] in terms of performance evaluation over the region.…”
