Interannual variability of precipitation and moisture flux on Amazon using QTCM
The aim of this study was to evaluate the atmospheric response to the interannual variability patterns of Sea Surface Temperature in the areas of the Atlantic and Tropical Pacific, analyzing the seasonal cycle of Moisture Flux Divergence on the regions of the North and South Atlantic Tropical and Am...
