Abstract Extreme precipitation often persists for multiple days with variable duration but has usually been examined at fixed duration. Here we show that considering extreme persistent by complete event duration, rather than a temporal period, is necessary metric to account the complexity of changing precipitation. Observed global mean annual‐maximum significantly stronger (49.5%) extremes daily extremes. However, both globally observed and modeled rates relative increases are lower compared...
Abstract Extreme precipitation occurring on consecutive days may substantially increase the risk of related impacts, but changes in such events have not been studied at a global scale. Here we use unique dataset based situ observations and multimodel historical future simulations to analyze frequency extreme (EPCD). We further disentangle relative contributions variations intensity temporal correlation understand processes that drive EPCD. Observations climate model show EPCD is increasing...
Abstract A comprehensive dataset of daily rainfall covering the period from 1972 to 2002 was used compute climatology and trend occurrence intensity heavy, weak normal events on Northeast Brazil (NEB). For selection events, we technique quantiles identified using nonparametric Mann–Kendall test. The heavy are modulated by La Niña El Niño occurrences in general they presented negative concerning number episodes positive rainfall.
Abstract. Northeast Brazil (NEB) has an extensive coastal area, often hit by natural disasters that bring many social and economic losses. The objective of this work was to study the synoptic environment associated with a heavy rainfall event (HRE) on coastland NEB. We used daily data for area NEB between states Rio Grande do Norte Bahia, divided into two subregions: north south coastland. This obtained from hydrometeorological network managed Agência Nacional de Águas reanalysis ERAInterim....
Climate extreme events are becoming increasingly frequent worldwide, causing floods, drought, forest fires, landslides and heat or cold waves. Several studies have been developed on the assessment of trends in occurrence events. However, most these used traditional models, such as Poisson negative binomial models. Thus, main objective this study is to use a space–time data counting approach modeling number days with precipitation an alternative commonly statistical methods. The area...
Abstract The aim of this work is to evaluate how the Regional Climate Model ( RegCM4 ) able simulate precipitation in Northeast Brazil NEB ). Therefore, high‐resolution (grid spacing 20 km) simulations during autumns 1998 and 1999 were performed. model was capture regional inter‐annual differences . showed improved prediction concerning intensity spatial distribution rainfall, relative Era Interim reanalysis dataset. experiment based on Emanuel MIT parameterization tends overestimate...
Human immunodeficiency virus (HIV) infection is a health problem in Brazil and worldwide. Without treatment, the can progress to Acquired Immunodeficiency Syndrome (AIDS), with high mortality potential. The objective of this study was analyze time trend AIDS Brazil, macro-regions, federal units their respective capitals, from 2012 2022. This time-series all deaths included annual number crude standardized rates. Joinpoint regression model used for analysis Annual percentage change (APC)...
