Record #173542:

A model of the zonally averaged stratification and overturning in the Southern Ocean / Dirk Olbers, Martin Visbeck.

Title: A model of the zonally averaged stratification and overturning in the Southern Ocean / Dirk Olbers, Martin Visbeck.
Author(s): Olbers, Dirk.
Visbeck, Martin.
Date: 2005.
In: Journal of Physical Oceanography. (2005.), Vol. 35(7) (2005)
Abstract: Describes model based on zonally and temporally averaged theory to explain conversion of North Atlantic deep water (NADW) into Antarctic intermediate water (AAIW). Model includes small-scale mixing, eddy transport and diffusion, fluxes of momentum and buoyancy at sea surface to explain unique stratification of Southern Ocean with southward uprising isopycnals and northward flux of AAWI. Uses applied wind stress and surface density flux to determine zonal mean density stratification and baroclinic transport of Antarctic Circumpolar Current (ACC), and discusses role and importance of Ekman and eddy-induced advection and pumping, mixing, surface buoyancy flux and eddy-induced diffusion in shaping stratification. ACC transport is shown to have contribution forced by local wind stress, as well as contribution relating to nonlocal forcing by wind stress and density flux over entire Antarctic zone.
