O objetivo principal do presente trabalho foi observar a capacidade do modelo BRAMS e sua sensibilidade em simular a ocorrência de sistemas Zona de Convergência do Atlântico Sul – ZCAS, com a finalidade de observar o comportamento do fenômeno e sua interação com a escala interanual. Foram selecionados dois eventos de ZCAS: de 02 a 06 de dezembro de 2009 (durante a fase El Niño) e de 27 a 31 de dezembro de 2010 (durante a fase La Niña). A análise da mesoescala revela importantes variações dinâmicas relacionadas à ZCAS para ambos os casos. Todas as variáveis apresentam coerência e o BRAMS conseguiu simular bem a área principal de atuação da ZCAS, tanto para o caso de El Niño (2009) quanto para o caso de La Niña (2010).

Use of Atmospherics Parameters for the Detection of Episodes of SACZ in El Niño/La Niña Years through BRAMS
ABSTRACT
The main objective of this study was observe the ability of the BRAMS model and its sensitivity in simulating the occurrence of systems Convergence Zone of the South Atlantic – SACZ, with the purpose to observe their behavior and interaction with the interannual scale. Were selected two SACZ events: from 02 to 06 December 2009 (during the El Niño) and 27 to 31 December 2010 (during the La Niña). The Mesoscale analysis reveals important dynamic variations related to SACZ in both cases. All variables show coherence and BRAMS could simulate well the main area of activity of the SACZ, both for the case of El Niño (2009) as to the case of La Niña (2010).
