During the summer of 2006, the African Monsoon Multidisciplinary Analysis (AMMA) Special Observing period 3 (SOP3) occurred. One important aspect of AMMA was the enhancement of radiosonde stations in countries throughout West Africa. These additional radiosoundings allow for investigation of monsoon dynamics, synoptic features (African Easterly Waves) and mesoscale convective systems and their interaction with the large-scale environment. For the period of August 15-September 30 in association with the NASA African Monsoon Multidisciplinary Analysis (NAMMA) enhanced radiosoundings were undertaken in Mauritania, Senegal and Guinea. In this presentation we compare all radiosoundings along coastal areas (Nouadhibou and Nouakchott, Mauritania; Dakar and Kawsara, Senegal; Conakry, Guinea) during the period of August 15-September 30. We also examine these stations and their relationships to AEW passage, mesoscale convective systems and Saharan Air Layer (SAL) intrustions. wrf recording  Recorded presentation
