Record #179581:

Interdecadal variability of the Southern Ocean / Andrew McC. Hogg, Jeffrey R. Blundell.

Title: Interdecadal variability of the Southern Ocean / Andrew McC. Hogg, Jeffrey R. Blundell.
Author(s): Hogg, Andrew McC.
Blundell, Jeffrey R.
Date: 2006.
In: Journal of Physical Oceanography. (2006.), Vol. 36(8) (2006)
Abstract: Investigates intrinsic variability of Antarctic circumpolar current using idealized wind-driven model with three quasigeostrophic layers, steady wind stress forcing and no diabatic effects. Despite idealized nature of model, simulations display robust mode of low-frequency variability in flow, which is shown to be dependent upon explicit simulation of dynamics of mesoscale eddies. As such, variability is sensitive to stratification, horizontal viscosity, bottom stress and topography. Diagnoses energetic balance of variability, and proposes driving mechanism that involves positive feedback between generation of eddies through baroclinic instabiltiy and dynamics of mean circulation.
