abstract = "The formation of dense water masses at polar regions has been
largely influenced by climate changes arising from global warming.
In this context, based on ensemble simulations with a coupled
model we evaluate the meridional shift of a climate signal (i.e.,
a cold and fresh water input pulse generated from melting of
positive Antarctic sea ice (ASI) extremes) towards the Tropical
Atlantic Ocean (TAO). This oceanic signal propagated from Southern
Ocean towards the equator through the upper layers due to an
increase in its buoyance. Its northward shift has given by the
Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water
(AAIW) flows, that inject cold and fresh mode/intermediate waters
from into subtropical basin. The signal has reached low latitudes
through the equatorial upwelling and spreads out southwards,
through the upper branch of southern subtropical gyre. We
concluded that 10 years of coupled simulations was enough time to
propagate the climate signal generated by ASI positive extremes
melting, which reached TOA around 2 year later. The oceanic
connection between Southern Ocean and TAO is indeed established
within the timescale analyzed in the study (10 years).
Nonetheless, the period needed to completely dissipate the
disturbance generated from ASI seems to be longer.",
