Abstract

Numerical experiments with ocean-atmosphere coupled models and observational data will be used in the investigation of physical mechanisms which control the interannual and decadal modes of climatic variabilities in the South Atlantic and their teleconnections with variations in other regions of the planet. In particular it is intended to investigate the correlations between the dipolar mode of sea surface temperature anomalies in the South Atlantic and variabilities in two areas: the region of formation of deep waters in the North Atlantic and the zone of atmospheric convergence over Brazil (South Atlantic Convergence Zone - SACZ). Connections between the South Atlantic and these two regions were observed in results of previous projects, financed by FAPESP. In addition to these teleconnections, another objective of the present Project will be the study of the impact of the SST anomalies on the shallow circulation cell of the Subtropical South Atlantic.
