LONG-TERM GOALS. This effort contributes to a better understanding of the deep convective process in the ocean. In particular we are interested to evaluate the skills of a prediction system based on real time data in combination with ocean models to forecast the deep convective activity in a given region from a few weeks up to a few month in advance. More recently we realized that one of the critical parameter is the representation of lateral fluxes due to mesoscale eddies. We have completed a study to quantify the climatological mean lateral eddy fluxes. OBJECTIVES. C Apply and evaluate and improve, in real time, a minimum prediction system to forecast the convective activity several weeks in advance. C Assess the relative importance of one-dimensional mixing physics versus lateral effects due to mesoscale eddies or other variable flows. C Quantify the strength of the eddy induced property transfer.
