Abstract Oceanic heat sources disturb the atmosphere, which, to come back its initial state, disperses waves. These waves affect climate in remote regions, characterizing teleconnection patterns. In this study, we describe eight patterns that South America climate: El Niño–Southern Oscillation (ENSO), Pacific Decadal (PDO), Atlantic Multidecadal (AMO), Tropical Dipole (TAD), (SAD), Southern Annular Mode (SAM), Madden–Julian (MJO), and Indian Ocean (IOD). Precipitation winds at 850‐hPa...
Abstract In January 2020, an extreme precipitation event occurred over southeast Brazil, with the epicentre in Minas Gerais state. Although rainfall frequently occurs this region during wet season, led to death of 56 people, drove thousands residents into homelessness, and incurred millions Brazilian Reais (BRL) financial loss through cascading effects flooding landslides. The main question that arises is: To what extent can we blame climate change? With mind, our aim was assess...
Abstract In March 2020, an extreme rainfall in Baixada Santista, Brazil, led to a series of landslides affecting more than 2800 people and resulting losses exceeding USD 43 million. This attribution study compared two large ensembles the UK Met Office Hadley Centre HadGEM3-GA6 model that represented event with without effects anthropogenic climate change. Antecedent conditions on different timescales are considered, namely 60-day (Rx60day) which relates soil moisture 3-day (Rx3day)...
Abstract The South Atlantic Subtropical Anticyclone (SASA) is a key component of large-scale atmospheric circulation and responsible for driving the climate in eastern Brazil western Africa. Climate projections under warming scenarios suggest strengthening, as well westward southward expansion this system. However, little known about how combination global intervention affects To address this, SASA was identified from 2015 to 2099 set with without stratospheric aerosol injection (SAI)....
Extreme rainfall events represent a substantial risk to regions across the globe, including Central Europe. The 2002 European flood was devastating natural disaster affecting countries like Germany, Austria, Czech Republic, and Hungary. Intense rainfall, saturated soils, overflowing rivers caused severe flooding, displacing many leading significant loss of life. With damages exceeding €20 billion, it remains one Europe’s most costly events, heavily impacting historic...
Abstract This study investigates the influence of upper‐level potential vorticity (PV) structures on surface cyclogenesis in central‐eastern South America using 1979–2017 ERA‐Interim reanalysis data. Surface cyclones are identified three regions ( Argentina , Uruguay and SEBrazil ) it is quantified how often PV streamers cutoffs co‐occur with events. There interesting regional seasonal differences: occur mainly summer, both summer winter. In regions, associated most frequently at 320 K,...
Abstract In March 2019, the tropical western South Atlantic Ocean (∼16.5°S) registered first pure cyclogenesis since beginning of satellite era, which Brazilian Navy named Iba. This study presents a description synoptic features and meteorological mechanisms contributing to Iba's initial cyclonic vorticity as well anomalous patterns linked this unprecedented cyclogenesis. Moreover, general lifecycle is provided. The genesis Iba was cyclone (00:00 UTC on 22), it underwent subtropical (18:00...
Southeastern Brazil is the most populated and economically developed region of this country. Its climate consists two distinct seasons: dry season, extending from April to September, precipitation significantly reduced in comparison that wet which extends October March. However, during nine days 2016 successive convective systems were associated with atypical events, tornadoes at least one microburst over southern part region. These events led flooding, damages buildings, shortages...

Abstract The eastern coast of South America is a cyclogenetic region in terms extratropical cyclones and, lower number, subtropical that are more frequent austral summer and autumn. However, June 2021, an unusual cyclone developed near the boundary Uruguay southern Brazil, initially having features later undergoing transition. At 1200 UTC 29 June, Brazilian Navy named it as Raoni . This study aims to describe synoptic evolution address physical drivers for transition based on ECMWF‐ERA5...
Abstract In this study, we estimated near‐surface wind speed 100‐year return values over the southwestern South Atlantic Ocean, using present‐day (1979–2018) simulations from regional climate models (RCMs) WRF and RegCM4. Extreme events, associated with hazardous conditions coastal oceanic areas, must be well represented in numerical for risk assessment, few studies focused on added value offered by RCMs to extremes. Events were selected peaks‐over‐threshold method extremes calculated...

Dry conditions occurred over São Paulo state (southeastern Brazil) from February to July 2018, causing the driest semester in 35 years. Socioeconomic impacts included a record number of fire spots, most adverse pollutant dispersion 3 years and winter's lowest water reservoirs stored volume 17 This paper discusses climate drivers onset persistence dry conditions, with special attention intraseasonal forcing. Barotropic atmospheric circulations forced by Pacific-South America teleconnection...
Abstract Winds and precipitation are two meteorological variables of great impact on the economy society, especially when extreme events occur. The objective this study is to investigate subtropical cyclone (SC) impacts near‐surface wind extremes (defined by 95th percentile) in South Atlantic basin. For period 1979–2015, analysis used reanalysis data (ERA5 Climate Forecast System Reanalysis [CFSR]) estimated from Tropical Rainfall Measuring Mission (TRMM) considering extended warm (from...
