%X Diagnostic analyses of two episodes observed during 1954-55(La Nina) and  1972-73(El Nino) over tropical Pacific Ocean are reported.  These years were marked by reversed impact on the regional precipitation observed over the northeastern South America . The  observational results showed that , in the  Pacific Ocean, the  La Nina stayed  well configured during both summer and autumn of 1954-55, however the El nino presented its mature  phase during  summer of 1972-73 and an abrupt decline surinf autumn  of 1973. On the other  hand, the  large -scale oceanic and atmosphere patterns related  to the  intertropical Atlantic SST gradient, created dynamic  conditions that modulated  the positioning of ITCCZ in the  equatorial Atlantic and  regualted significantly the raunfall anomalies observed int he  northeastern South America, overcoming the effect of the ENSO mode  observed in the Tropical Pacific.
