abstract = "Este trabalho analisa a variabilidade clim{\'a}tica do
fen{\^o}meno El Niņo-Oscila{\c{c}}{\~a}o Sul (ENOS) e os
padr{\~o}es de grande escala do sistema acoplado oceano-atmosfera
com o objetivo de melhor compreender os processos que provocaram
altern{\^a}ncia de regimes an{\^o}malos de
precipita{\c{c}}{\~a}o da Regi{\~a}o Nordeste do Brasil (NEB)
nos {\'u}ltimos quatro anos, com enfoque no trimestre
mar{\c{c}}o a maio (MAM). Os resultados indicam que o excesso de
precipita{\c{c}}{\~a}o ocorrido em 2009 e a seca rigorosa de
2012 tiveram uma fundamental contribui{\c{c}}{\~a}o do
padr{\~a}o do Oceano Atl{\^a}ntico tropical (ATL), e reduzida ou
nula contribui{\c{c}}{\~a}o do Oceano Pac{\'{\i}}fico
equatorial (PAC). Por outro lado em 2010, o regime deficiente de
precipita{\c{c}}{\~o}es no NEB p{\^o}de ser explicado pelo
epis{\'o}dio El Niņo configurado no PAC. No caso de 2011, os
padr{\~o}es de ambos os oceanos foram favor{\'a}veis para o
regime chuvoso observado na regi{\~a}o. ABSTRACT This study
analyses the El Niņo-Southern Oscillation (ENSO) climate
variability and coupled ocean-atmosphere large-scale patterns with
the aim of better understanding the processes leading to
alternated anomalous precipitation regimes in the Northeast region
of Brazil (NEB) during the last four years, focusing in the period
from March to May (MAM). Results indicate that the excessive
rainfall occurred in 2009 and the severe drought of 2012 had
fundamental contribution from the tropical Atlantic Ocean (ATL),
and reduced or null contribution from the equatorial Pacific Ocean
(PAC). On the other hand, in 2010, the lack of precipitation in
the NEB was explained by the El Niņo episode in the PAC. For the
period 2011, the patterns of both oceans were favorable to the
observed abundant rainfall regime.",
