| Résumé | Modeling and observational evidence indicate that interannual variabilities of dynamic height and sea surface temperature (STT) in the Eastern part of the Tropical Atlantic ocean (Gulf of Guinea) are largely induced by preceding fluctuations in wind stress, mainly in the Western Equatorial basin. A wind-driven linear oceanic model is used here to test the possibility of forecasting the abnormal dynamic heights. A control run of the model, forced by 1964-1993 wind stress monthly means, is first conducted. Yearly test runs (1964-1994) are subsequently performed from January to August by forcing the model with observed winds from January to May and then by May wind assumed to persist from June to August. During the last three decades the largest deviations of dynamic height simulated by the control run in the Gulf of Guinea in boreal summer would have been correctly forecast from wind data only related to conditions in May of each year.
