| Abstract | South America represents an interesting area concerning seasonal to interannual and longer climate variability. The largest fraction of the continent is within the tropics, where seasonal climate predictability is higher, if compared to mid latitudes, and thus can benefit a large number of people. Also, it encompasses a few important elements of the climate system, like the Amazon rainforest, which covers a considerable fraction of the continental area and represents an important source of upper level mass and heat at lower latitudes; thus contributing both to the general circulation of the atmosphere and to the local climate (Buchmann et al., 1995). It is also subject to and interferes in two convergence zones: the Intertropical Convergence Zone (ITCZ) and the South Atlantic Convergence Zone (SACZ). The ITCZ is modulated by surface features, like the interhemispheric gradient of Sea Surface Temperature (SST) anomalies over the equatorial Atlantic (Hastenrath and Druyan, 1993; Wagner, 1996; Chang et al., 2000), and it modulates interannual variability of seasonal rainfall over eastern Amazon and northern Nordeste (Hastenrath and Heller, 1977; Moura and Shukla, 1981; Nobre and Shukla, 1996). Atmospheric general circulation models (AGCM) simulate seasonal rainfall interannual variability over Nordeste strikingly well when observed global tropics SST are prescribed (Goddard and Mason, 2002; Marengo et al., 2003). The SACZ, on the other hand, is also influenced by SST anomalies over the southwestern tropical Atlantic, has a strong impact on the rainfall regime over southern Nordeste, Southeast and Southern Brazil, and contributes to modulate underlying SSTs over the SW tropical Atlantic (Chaves and Nobre, 2004). Differently from the ITCZ, however, the SACZ is observed predominantly over negative SSTA (Robertson and Mechoso, 2000), suggesting that an atmospheric-forcing coupling is operative at zero lag. AGCM experiments using direct SST thermal forcing generates simulations with near zero or even negative skill simulating SACZ (i.e., rainfall) variability (Marengo et al., 2003). The high reproducibility of Nordeste, and to some extent over southern Brazil, seasonal rainfall by AGCMs contrasts with the low reproducibility of seasonal rainfall over southeastern Brazil, indicating that different processes shall be operating to modulate seasonal rainfall over those regions. |
