A pluviosidade na Amazônia meridional: variabilidade e teleconexões extra-regionais

The Amazon region is one of the longest warm and moist areas of the Planet, with rainfall around 2300 mm/year on average, and up to 5000 mm/year in its western sector. The variability of rainfall in the region receives direct influence of the Atlantic and Pacific oceans, such as what occurred in 200...
