abstract = "The main objective of this study was to evaluate the effects of
increasing greenhouse gases (GHGs) and total deforestation of the
Amazon on extreme rainfall events in the Amazon basin. In order to
quantify these impacts, numerical experiments were performed with
the Eta regional climate model forced from initial and boundary
conditions from the BESM, HadGEM2-ES, and MIROC5 earth system
models. In the experiment related to the increase in GHGs,
numerical simulations were performed according to the IPCC RCP8.5
scenario. The effect of deforestation was quantified via an
experiment in which the forest in the Amazon basin was replaced by
areas of degraded pasture in the Eta model. For the analyses of
the changes in extreme rainfall events, the multi-model ensemble
technique was used. The results were evaluated in terms of
anomalies relative to the sensitivity and control experiments. In
the results, it was observed that in an RCP8.5-type GHG emission
scenario there is a statistically significant increase in the
maximum number of consecutive days without rain, a reduction in
the maximum number of consecutive rainy days, reduction in total
annual precipitation, and reduction in maximum annual
precipitation accumulated over one and 5 days, respectively. The
results for the scenario with increased GHGs and large-scale
deforestation in the Amazon basin are similar to the RCP8.5
scenario, but the intensity of changes in climate indices is
significantly greater. It was also verified that the changes in
the climatic indices are strongly associated with alterations in
the energy balances at the surface and, consequently, in the
large-scale circulation. In general, it can be highlighted that
the climate in the Amazon region is strongly dependent on the
presence of the forest.",
