Adjustment of the Southern Ocean to wind forcing on synoptic time scales / Wilbert Weijer, Sarah T. Gille.

Title: Adjustment of the Southern Ocean to wind forcing on synoptic time scales / Wilbert Weijer, Sarah T. Gille.
Author(s): Weijer, Wilbert.
Gille, Sarah T.
Date: 2005.
In: Journal of Physical Oceanography. (2005.), Vol. 35(11) (2005)
Abstract: Uses constant-density, multilevel model of Southern Ocean to examine ocean response to wind forcing over broad range of frequencies, with particular reference to role of barotropic modes in ocean response to wind stress variability. Low frequency range below 0.2 cpd is dominated by "almost- free-mode" response in region where contours of f/H are obstructed by only a few bathymetric features. Topographic form stress rather than friction is dominant decay mechanism of Southern Mode, leading to spindown time scale on order of three days. For high frequency range above 0.2 cpd, circumpolar transport is dominated by resonant excitation of oscillatory modes. "Active" response of ocean leads to strong changes and even discontinuities in phase relation between transport and wind stress.
