Numerous theories attempt to describe the termination of sea surface temperatures (SST) anomalies in the eastern equatorial Pacific Ocean associated with the El Nino-Southern Oscillation (ENSO). The termination of ENSO is not competely understoon however, as there are several significant observational features that are not incorporated in, or reproduced by existing theories. The most glaring omission is the southward shift of ENSO related to surface wind anomolies near the event peak. This study will provide a comprehensive analysis of ENSO event termination, improving our understanding of the role of these neglected features. This will enhance skill in inter-seasonal climate forecasting and aid those sectors reliant on accurate prediction.
