Description:
1This study evaluates the Antarctic Circumpolar Wave
(ACW) as simulated by the SINTEX coupled model. We
found evidence that sea-ice treatment plays a crucial role
on simulating the ACW. In particular, SST anomalies at
interannual time scales describe a propagating ACW-like
pattern when a dynamic thermodynamic sea-ice model
is coupled with the ocean, but when sea-ice is relaxed
to climatology, anomalies occur as zonally symmetric
patterns that do not propagate in longitude. Moreover,
from the experiment with an active sea-ice component
we saw that ACW-like oscillations are strongly modulated
by low frequency variability. Our result adds some
extra confidence to previous studies based on relatively
short series of observed data.
