Based on our assessment we found the following models better in representing climatology and showing ENSO- African monsoon relations. MPI-ESM-MR HadGE2–ES IPSL-CM5A - MR GFDL–CM3 CNRM All the above models predict that the NINO 3.4 temperature, EEA precipitation and NEA precipitation would increase by the end of 21 st century. However the models disagree over the projection for Sahel precipitation.
