abstract = "This paper analyses the relations between the El Niño/Southern
Oscillation (ENSO) mode in the tropical Pacific and the sea
surface temperature (SST) modes in the South Atlantic for the 1900
2006 period. In the South Atlantic, two modes are analysed in more
detail: the South Atlantic dipole (SAD) mode, with centres at
(15°S, Greenwich longitude) and at (37.5°S, 25°W) and the
southwestern South Atlantic (SWSA) mode, with centres at (30°S,
40°W) and at the southern midlatitudes. The ENSO and SAD modes are
lagged or lead connected depending on the period of analysis. An
El Niño (a La Niña) precedes by up to 6 months the establishment
of a positive (negative) SAD mode during the 1920 1930 and 1940
1980 periods. Otherwise, a positive (negative) SAD mode precedes
by up to 1 year the establishment of a La Niña (El Niño) during
the 1975 2000 period. On the other hand, the SWSA is strongly
driven by the ENSO. The effects of both the SAD and SWSA modes on
the South American rainfall are also discussed on a seasonal
basis. In general, the SAD (ENSO) mode has a weak influence on the
ENSO-related (SAD-related) rainfall anomalies over South America.
On the other hand, in general, the SWSA and ENSO modes have a
combined effect on rainfall of the southern and southeastern
regions of South America. A particularly important result of the
present analysis for climate monitoring and forecasting purposes
seems to be the changing relations between the SAD and ENSO
modes.",
