Resumen:
Some aspects of winter precipitation over Southeastern
South America (SESA) during El Nino (EN) and La Nina
(LN) events are analyzed in this paper. In JuneJuly, the
precipitation over a vast area in the north of SESA is similar
in both ENSO phases and higher than in neutral cases. On
the other hand, there is a wide rainfall variability among EN
and among LN cases, which is not associated with SST of
EN regions. Similar characteristics are observed in the
precipitation over the south of SESA. The obtained results
describe a nonlineal relationship between the SST of the
equatorial Pacific and the precipitation over most of the
southeast of South America during austral winter.
