Anticiclone Subtropical do Atlântico Sul Associado ao Modo Anular Sul e Impactos Climáticos no Brasil

Abstract: Resumo O objetivo deste estudo é investigar a precipitação pluvial e os ventos no Brasil associados ao anticiclone subtropical do Atlântico Sul (ASAS) nas diferentes fases do Modo Anular Sul (SAM). Na fase positiva (negativa) do SAM, o ASAS está posicionado anomalamente para sul (norte), assim como a Zona de Convergência Intertropical, contribuindo com aumento (redução) da precipitação pluvial na Região Norte (Norte e Nordeste). Assim, ventos mais intensos (fracos) são observados em algumas áreas no sul da Reg… Show more

“…Among the localities analyzed, the Santa Branca region deserves to be highlighted, as it presents statistical signi cance with a negative CWD trend of 0.6 days/year. This reduction in CWD can also be related to the southwestward expansion of SASA found in many studies (Reboita et al, 2019;Carpenedo and Ambrizzi, 2020;Marengo et al, 2020).…”

“…That is, when it is in the positive phase, it has negative (positive) geopotential height anomalies in the high (medium) southern latitudes, associated with the anomalous displacement of the SASA and ITCZ to the south. The opposite occurs during the negative phase of the SAM (Sun et al, 2017;Carpenedo and Ambrizzi, 2020).…”
