abstract = "To evaluate the individual and combined impacts of increasing
greenhouse gases and deforestation on extreme precipitation events
in the Amazon Basin, we carried out 4 numerical experiments with
the regional Eta model forced from the initial and boundary
conditions of the global HadGEM2-ES model: (1) control experiment
(CTRL); (2) RCP8.5 scenario; (3) DEFOREST scenario; and (4)
RCP8.5+DEFOREST scenario. To analyze changes in extreme rainy
events associated with the increase in greenhouse gases,
deforestation, and their combined effect, anomalies were
calculated from the sensitivity and control experiments. In the
RCP8.5 scenario, there was an increase in the maximum number of
consecutive dry days (CDD), a reduction in the maximum number of
consecutive wet days (CWD), a reduction in total annual
precipitation (PRCPTOT), and an increase in the maximum
precipitation accumulated in 5 consecutive days (RX5Day). The
DEFOREST scenario evidenced an increased CDD, and a reduction in
the other indices (CWD, PRCPTOT, and RX5Day). Furthermore, the
RCP8.5+DEFOREST scenario exhibited an increased CDD, and a
reduction in the other indices (CWD, PRCPTOT, and RX5Day), but
with more intense increases and reductions than observed in the
DEFOREST scenario. In general, towards the end of the 21st
century, the 3 scenarios are projected to increase the drought
period, mainly on the boundary between the Brazilian states of
Amazonas and Para.",
