A signature of potential tropical cyclones in the Eastern Atlantic can often be found in the wind fields from the radio soundings at Dakar, Senegal. During the period of august 15-September 30th, there were approximately 12 African Easterly Waves (AEWs), 12-13 Sahara Air Layer (SAL) outbreaks (identified by satellite) and 6 tropical cyclones (one TS, two CAT-1, two CAT-2, two CAT-3) that are linked to the AEWs. A number of these features had some impact on weather conditions in Senegal. In addition, there were 6-7 squall lines that passed by western Senegal (3 long-lived systems). Surface and upper air observations in a coastal environment provide insight on processes associated with the phenomena. Polarimetric radar, high and coarse density rain-gauge measurements, rawinsondes, 10 m flux tower, broadband IR/Solar measurements, MWR and aerosol optical depth measurements provide the observational base during this period. In this presentation, we highlight some of our findings and the linkage to aircraft measurements (DC-8 and FA-20) and the linkage to Tropical Cyclogenesis.
