                         precipita{\c{c}}{\~a}o ocorrido em 2009 e a seca rigorosa de 
                         2012 tiveram uma fundamental contribui{\c{c}}{\~a}o do

                         padr{\~o}es de ambos os oceanos foram favor{\'a}veis para o

                         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.",
