This study will use two tracking methods; an objective method as well as an automatic method, to identify and track AEWs at multiple levels. The magnitude, frequency, location, and speed of the AEWs will be compared between reanalysis products (e.g. JRA-55, CFSR, ERA-Interim) and the coupled historical simulations from the fifth phase of the Coupled Model Intercomparison Project (CMIP5). This will provide insight into the ability of global climate models to represent tracks of AEWs and the relationship with the simulated environment in the CMIP5 models. After establishing historical biases, the tracking techniques will be applied to future simulations within the CMIP5 experiments. Identifying the extent to which AEW track characteristics are changing will provide a better understanding of the future projections for Sahel rainfall and Atlantic TCs.
