             abstract = "In recent decades, the climate in North and Northeast Brazil has 
                         undergone significant changes, which indicate potential risks for 
                         water and food security due to increasing temperatures, changing 
                         precipitation patterns, and greater frequency of some extreme 
                         events. For example, there is evidence of changes in the strength 
                         of the hydrological cycles on North and Northeast Brazil river 
                         basins, but the magnitude and extension of the precipitation 
                         changes are highly dependent on the precipitation dataset under 
                         consideration and the methodology. Here, we analyze the 
                         precipitation trends in North and Northeast Brazil hydrological 
                         basins and the possible associated mechanisms and present the 
                         rainfall climatological cycles in these basins using 
                         multi-datasets. The results showed that, in most river basins, 
                         there is a clear distinction between the rainy and dry seasons, 
                         with a contrast between the basins of the North (which receive a 
                         higher amount of rainfall) and the Northeast Brazil (with low 
                         rainfall volume, especially in the Parna{\'{\i}}ba and Eastern 
                         Northeast Atlantic basins). Moreover, the annual rainfall has 
                         undergone an increasing trend in western Brazil river basins and a 
                         decreasing trend in the eastern. This eastwest dipole is 
                         associated with the strengthening (weakening) of the Walker and 
                         Hadley circulations in western (eastern) Brazil in recent decades. 
                         A multidecadal variability is seen to modulate the precipitation 
                         changes, which is in phase with the AMO cycle. CMIP6 detection and 
                         attribution experiments showed that both natural and anthropogenic 
                         factors can play a role in the recent changes observed in northern 
                         Brazil river basins.",
