Multiscale analysis and simulations of an extreme rainfall event in Northeast Brazil with the MPAS model
Extreme rainfall events are becoming increasingly frequent in Northeast Brazil (NEB). The state of Alagoas, located on the eastern coast of the region, is one of the most affected areas in recent years, with records of high-magnitude events over the past four years. These events cause significant so...

Easterly wave disturbances on tropical south Atlantic and their impact over northeast Brazil.
This study presents a 21-year climatology (19982018) of Easterly Wave Disturbances (EWDs) over the Tropical South Atlantic (TSA). The identification of these systems was performed subjectively using infrared satellite images and fields of relative vorticity and streamlines at 1000, 850, 700, 500, an...

Are flash droughts intensifying in Brazil?.
Flash droughts are a type of drought that develops abruptly in response to rainfall deficits and high evapotranspiration that depletes soil water quickly. The speed and intensity can strongly impact both natural vegetation and crops, and the lack of predictability poses a major challenge to early wa...

Spatio-temporal assessment of extreme precipitation events in southeastern Brazil.
This study investigates the spatial and temporal variability of extreme precipitation in southeast Brazil (S & atilde;o Paulo, Minas Gerais, Rio de Janeiro, and Esp & iacute;rito Santo) between 1981 and 2020, using the generalized extreme value (GEV) distribution. The region, which plays a vital rol...
