While it is understood that over half of all Atlantic tropical cyclones (TCs) originate from African Easterly Waves (AEWs) exiting the western African coastline, it is less understood how AEWs of similar intensity do not develop into similar intensity TCs. This case study investigates large-scale environmental influences on three different developing and non-developing AEWs that had similar intensity and amplitude as they propagated into the Atlantic. Though the parameters in each AEW were practically identical over Africa, the TCs that developed from them were very different. The first two AEWs investigated developed into Hurricane Hugo in September 1989 and Tropical Depression 14 (TD14) in September 2003, while the third AEW in 2000 did not develop into a TC at all. The results presented will highlight potential mechanisms that shed light as to why similar intensity disturbances end up having different outcomes. All of these results are based on findings using the Weather Research & Forecast (WRF) model and European Centre Medium Range Weather Forecast (ECMWF) reanalysis data.
