Short summary
The onset and demise of the rainy season in Amazonia are assessed in this study using meteorological data from the GoAmazon experiment for the 2014–15 rainy season. The onset of the rainy season was strongly associated with changes in large-scale circulation in the region, and our analyses using regional thermodynamic indices suggest that local changes such the regional thermodynamic characteristics may have been less important on the occurrence of the onset compared to large-scale circulation.
The onset and demise of the rainy season in Amazonia are assessed in this study using...
