abstract = "Drought causes serious social and environmental problems that have
great impact on the lives of thousands of people all around the
world. The purpose of this research was to investigate the trends
in humid conditions in the northeast of Brazil (NEB) in the
highest climatic precipitation quarters, NovemberDecemberJanuary
(NDJ), FebruaryMarchApril (FMA), and MayJuneJuly (MJJ), through
the standardized precipitation and evapotranspiration index
(SPEI), considering an alternative statistical approach.
Precipitation and potential evapotranspiration (PET) time series
for the calculation of the SPEI were extracted for the 1794 NEB
municipalities between 1980 and 2015 from a grid dataset with a
resolution of 0.25\◦ × 0.25\◦ using the bilinear
interpolation method. The trends and statistical significance of
the SPEI were estimated by quantile regression (QR) and the
bootstrap test. In NDJ, opposite trends were seen in the eastern
NEB (~0.5 SPEI/decade) and in the south (~\−0.6
SPEI/decade). In FMA, most of NEB presented negative trends in the
0.50 and 0.95 quantiles (~\−0.3 SPEI/decade), while in MJJ,
most of NEB presented positive trends in all quantiles studied
(~0.4 SPEI/decade). The results are consistent with observational
analyses of extreme rainfall.",
