Abstract

African Easterly Waves (AEWs) are the most important rain modulators in the sub-Saharan Africa and precursors for tropical cyclone genesis in the Atlantic. While most previous studies have focused on the mean structure and dynamics of AEWs, evidence has shown that AEWs can vary substantially in terms of their structure and characteristics. Therefore, the overarching goal of this dissertation is to document the variability of AEWs and understand its causes. The goal is accomplished through two different but complementary approaches: (1) statistical analysis and (2) vorticity tracking.
