| Abstract | This study presents the daily atmospheric circulation patterns at surface and altitude related to the South Atlantic Convergence Zone (SACZ) events that occurred between 2007 and 2017. For this analysis, Principal Pattern Sequence Analysis (PPSA) and sea level pressure and geopotential height reanalysis were used. Four typical atmospheric circulation patterns associated with SACZ episodes were identified. Three of them are related to the propagation of a cold front toward southeastern Brazil with a post-frontal anticyclone moving over the Atlantic Ocean. The fourth pattern is associated with the presence of a cut-off low centered over the central-south region of Brazil that induces moisture transport from the Atlantic Ocean and from the Amazon basin to most of southeastern Brazil. Considering the first three patterns, they represent, respectively, a frontal wave, a classical cold front, and a slow-moving cold front. All of these patterns provide permanent northwesterly winds in the lower troposphere over southeastern Brazil from two days before the SACZ occurrence. RESUMEN: Este trabajo presenta los patrones diarios de circulación atmosférica en superficie y en altura relacionados con los eventos de la Zona de Convergencia del Atlántico Sur (ZCAS) ocurridos entre 2007 y 2017. Para ello se utilizaron el análisis de patrones de secuencias principales (APSP) y datos de reanálisis de presión a nivel medio del mar y de altura geopotencial. Se identificaron cuatro patrones típicos de circulación atmosférica asociados con episodios de la ZCAS. Tres de ellos están relacionados con la propagación de un frente frío hacia el sureste de Brasil con un anticiclón postfrontal que se mueve sobre el Océano Atlántico. El cuarto patrón está asociado con la presencia de una baja segregada centrada sobre la región centro-sur de Brasil que induce el transporte de humedad desde el Océano Atlántico y desde la cuenca del Amazonas hacia gran parte del sureste de Brasil. Los tres primeros patrones representan, respectivamente, una onda frontal, un frente frío clásico y un frente frío con un lento desplazamiento. Todos estos patrones producen vientos persistentes del noroeste en la troposfera baja sobre el sureste de Brasil desde dos días antes de la ocurrencia de eventos de la ZCAS. | |||
