The impacts of global warming on rainfall in West Africa were examined using a numerical
framework for 5 monsoon years (2001, 2007, 2008, 2010, and 2011). Rainfall characteristics
over the three climatic zones, Guinea coast, Savannah, and Sahel, were analyzed. The
potential changes associated with global warming were assessed by the pseudo-global
warming (PGW) downscaling method. Multiple PGW runs were conducted using climate
perturbation from the 40-member ensemble of the Community Earth System Model version 1 …

A set of numerical experiments was conducted in order to investigate the impacts of global
warming on West African monsoon rainfall for selected five years. The experiments varied
different cumulus, microphysics and planetary boundary layer parameterization schemes.
