Abstract

The southwestern and southern sectors of the Atlantic Ocean are of great relevance for studies of ocean-atmosphere interaction, especially because of their dynamic and thermodynamic characteristics that modulate mass and energy exchanges and influence the weather and climate of South America. There are several methods used to calculate heat fluxes, including Bulk parameterization (BP) and Eddy Covariance (EC). The present proposal aims to obtain transfer coefficients that allow estimating heat fluxes in the Southwest Atlantic and Southern Ocean. This will be achieved through the combination of these two methods (BP and EC) to reduce uncertainties about these processes and generate more reliable results. Using a turbulent data base already collected in situ, combined with remote sensing data and atmospheric and oceanic reanalysis, Artificial Intelligence (Neural Networks) will be used so that analyzes can be carried out for the entire southwest and southern portion of the Atlantic Ocean. By obtaining these transfer coefficients, it is expected to advance knowledge, mainly from a dynamic and thermodynamic point of view, of the Southwest Atlantic Ocean/Southern Ocean.
