Abstract The influence of the Plata, the second largest river in
South America, extends along a coastal strip of 1300 km.
Historical hydrographic and wind data and numerical
simulations are combined to determine the seasonal and
interannual variability of the Plata plume and its relationship
to the magnitude of the river discharge and the intensity and
direction of the wind stress. Our results indicate that the
seasonal variability of the river plume is controlled by the
alongshore component of the wind stress. During El Niño
the effects of the wind and precipitation anomalies tend to
compensate each other, preventing anomalous northeastward
plume extensions associated to large outflow events.
Numerical experiments confirm this finding and indicate
that during El Niño the discharge from the Plata River
spreads offshore.
