The contribution of African easterly waves to monsoon precipitation in the CMIP3 ensemble

African easterly waves (AEWs) are a major source of synoptic‐scale rainfall variability throughout West Africa. Given the persistent uncertainty in the response of precipitation over West Africa to enhanced greenhouse forcing, we analyze the contribution of AEWs to the simulation of precipitation over West Africa in the Coupled Model Intercomparison Project Phase 3 (CMIP3) ensemble of general circulation models. Nearly all models that simulate...
