- Abstract
The amount and spatial and temporal distributions of rainfall determine the type of natural vegetation, agricultural exploration potential and availability of water resources. However, the rainfall are directly dependents to the general circulation of the atmosphere and changes in your behavior. On a global scale, the major influences are the result of the El Niño-Southern Oscillation (ENSO) and its different phases/intensities (El Niño - EN; La Niña - LN), which determine the precipitation anomalies in several regions. Given the large agricultural faculty of Mato Grosso State, Brazil, aimed to evaluate the influence of EN and LN phenomena for the watershed of the rivers Juruena, Teles Pires and Xingu, located in the Amazon region. The regions of the sources of river (High) of the three watershed have similarity in total annual rainfall. The different intensities of EN and LN cause greater influence in the rates of annual rainfall in the Teles Pires Watershed. EN-Intensive causes reductions in total annual rainfall in the lowlands (mouth rivers) of the three watersheds. LN-Intensive provides increase in annual rainfall regardless of the Teles Pires River region. LNmoderate reduces the total annual rainfall regardless of the watershed.
