abstract = "The spatio-temporal variability of the eddy kinetic energy (EKE)
in the South Atlantic Ocean (SAO) is investigated using 19 years
of satellite altimetry observations. The EKE in this region
presents different significant frequency modes. The interannual to
intrannual cycles dominate the EKE variability spectrum. Spatial
patterns of the EKE variance were also determined and associated
with the propagation of the Agulhas Current eddies across the SAO.
At the annual frequency, EKE anomalies are generated in the
Agulhas leakage (AL) region and propagate westward. The
interannual signal was associated with the Antarctic oscillation
and displays a stationary spatial oscillation pattern in the
Agulhas eddy corridor (AEC). This is the first time that a full
spectral analysis of the EKE variability in the SAO is produced.
Results show that the AEC is an important feature in the SAO, with
low (high) frequencies associated to the west (east) part of the
basin. The AL is a significant source of mesoscale variability to
the South Atlantic subtropical gyre.",
