In this project we propose to investigate the role of mesoscale and submesoscale turbulent activity in the Brazil-Malvinas Frontal System. Our premise is that both are important to explain the distribution of water properties suchs as T,S, nutrients and potential vorticity in the region because they condition the transformation and subduction of the different water masses. Using the 3-D primitive equation numerical model ROMS, we propose to investigate and quantify these processes. The main outcome expected is an improved understanding of the role played by the SouthWest Atlantic (SWA) in the thermocline ventilation and, more generally, in the Atlantic Meridional Overturning Circulation. This Project was motivated by discussions held during the SACOS Workshop and contributions to the SACCConsortium are anticipated.This project will be developed with the participation a Post-Doctoral fellow, Dr. XavierCapet, for whom we are requesting a fellowship from FAPESP. In addition to Dr. Capet, who will be mostly involved with the research plan described here, in a related project another post-doc felllow will develop a project on data ssimilation for ocean forecast, in which the model component is the one implemented as part of this work.
