Ciclones extratropicais

Abstract: O sistema atmosférico ciclone extratropical, que quando mencionado na mídia brasileira, em geral, causa pânico na população, é abordado aqui em linguagem simples. O objetivo é compartilhar - com todos os interessados no assunto - a definição e processo de formação dos ciclones extratropicais, os impactos que causam no Brasil e seus aspectos climatológicos no Hemisfério Sul e oceano Atlântico Sul. Esse estudo tem como base metodológica tanto a revisão da literatura quanto a utilização de dados estado-da-arte (r… Show more

“…10 Similarly, the PDO can also influence other systems like the El Niño Southern Oscillation (ENSO), potentially intensifying or mitigating the impacts of this phenomenon depending on its phase. According to Souza and Reboita 11 if ENSO and PDO occur during the same phase, the impacts of El Niño or La Niña could be amplified or attenuated. In summary, PDO events share similarities with those of ENSO, except in their temporality, where ENSO predominantly occurs with interannual variations, PDO exhibits decadal variability.…”

“…A costa leste da América do Sul apresenta três regiões propícias à formação de ciclones de escala sinótica: (a) os setores costeiros entre o sudeste e parte norte da região sul do Brasil, (b) o extremo sul do Brasil e Uruguai e (c) a costa do sul da Argentina (Gan & Rao, 1991, Reboita et al, 2010, 2017a,b, 2023, Gramcianinov et al, 2019, Crespo et al, 2021, Reboita & Marrafon, 2021. Os ciclones de escala sinótica se caracterizam por possuir diâmetro de ~10 3 km e tempo de vida médio de 3 dias (Bluestein, 1992, Reboita et al, 2010, 2017a.…”
