                         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

                         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.",
