Abstract

The El Niño Southern Oscillation (ENSO) is the leading
mode of climate variability and predictable on interannual
time scales. Recent studies suggest that the tropical Indian and
Atlantic Oceans influence the dynamics and predictability of
ENSO. Here we investigate these effects in a hybrid coupled
model consisting of a full complexity atmospheric general
circulation model (GCM) coupled to a strongly simplified
linear 2-dimensional ENSO recharge oscillator ocean model.
We find that the tropical Indian and Atlantic Oceans have
distinct effects on the dynamics and predictability. The
decoupling of the tropical Indian Ocean has a strong impact
onto ENSO dynamics, but the initial conditions of it have
only a small impact on the ENSO predictability. In contrast,
initial conditions of the tropical Atlantic have a stronger
impact on the predictability of ENSO, but the decoupling of
the tropical Atlantic has almost no effect on the ENSO
dynamics.
