The Météo-France « research on cyclones team » is willing to introduce its activities to the research community on cyclones. Our main goals are to improve the knowledge of the tropical cyclones and to make our progress available into operations. At first we would like to put the stress on our global model performances in forecasting cyclones over the south west indian ocean in comparison with the world community. Then we will focus on our planned activities on 2004, especially with the work undertaken with a non hydrostatic meso-scale model with sophisticated physics. This will be a laboratory to study the cyclones and we aim to improve the tracks and intensity of cyclones forecasts by the way. We will focus on the surface fluxes predicted by this type of model and hope to highlight the main defaults of currently operational models and then to correct them.
