African Easterly Waves and Cyclonic Activity over the Eastern Atlantic: Composite and Case Studies

Figure 3

Streamlines at 700 hPa for the 48 AEWs not associated with cyclones. The time sequence (𝑡−4,𝑡+1) considered in this study is from 4 days before to 1 days after the detection of AEWs at the mean genesis longitude for the 48 cyclones (30°W). 𝑇 represents the detection time of AEWs at this mean longitude. 𝑋 represents the location of AEWs axis.
