AB: One crucial component of any Observing System Simulation Experiment (OSSE) is the Nature Run (NR) which has the purpose of representing a virtual atmosphere from which observations can be simulated so that the impact of future instruments can be assessed. A community-based, Joint OSSE Nature Run (NR) was designed in an international collaborative effort and was produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) to contribute building a next-generation OSSE capability. In this work this new 13-month T511 Nature Run is being analyzed with emphasis on tropical development over the western African monsoon region and the tropical Atlantic. In particular, the NR representation of the African Easterly Jet (AEJ) and the characteristics of African Easterly Waves (AEWs) including their propagation and development in tropical cyclones are investigated. It is shown that, given the resolution limitations, the NR provides a very realistic representation of different processes such as genesis, development, extra-tropical transitions, track variability and multiple vortex interaction.
