TL;DR: In this paper, the authors synthesize the understanding of ENSO teleconnections to South America, focusing on the mechanisms and diversity of resulting Teleconnections, and outline the impacts of the El Nino-Southern Oscillation on South America. But, while the understanding has improved, with implications for prediction and projection, uncertainty remains in regards to the robustness of the impacts, interbasin climate interactions and interplay with greenhouse warming.

TL;DR: In this paper, a reduced-gravity, primitive equation OGCM is used to investigate the seasonal variability of the bifurcation of the South Equatorial Current (SEC) into the Brazil Current (BC) to the south and the North Brazil Undercurrent/Current (NBUC/NBC) system to the north.

TL;DR: In this paper, a two-layer finite element model is used to investigate the effects of bottom topography and coastline geometry on the coastal upwelling of the Southeast Brazilian continental shelf.

TL;DR: In this paper, observations and numerical simulations are used to investigate how different El Nino events affect the development of SST anomalies in the Atlantic and how this relates to the Brazilian northeast (NE) precipitation.

TL;DR: In this article, two indices were developed using three data sets: (1) climate, with IPCC climate extreme indices; (2) environmental, including land use, drainage systems, relief, slope, road density and hydrography; and (3) socioeconomic, including the Gini coefficient, Human Development Index, housing conditions and a poverty-related index.
