Projections of tropical cyclones and rainfall in the African Sahel could be improved with better understanding and representation of African easterly waves in models
Accurately simulating AEWs is critical to predicting Atlantic tropical cyclones and hurricanes, but new research supported by the Climate Variability and Predictability program, and accepted for publication in the Journal of Climate, demonstrates several shortcomings in CMIP5 models preventing accurate representation of AEWs.
