The Atmospheric Response to a Thermohaline Circulation Collapse: Scaling Relations for the Hadley Circulation and the Response in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The response of the tropical atmosphere to a collapse of the thermohaline circulation (THC) is investigated by comparing two 5-member ensemble runs with a coupled climate model (CCM), the difference being that in one ...
Heat Transport by Mesoscale Eddies in an Ocean Circulation Model
Publisher: American Meteorological Society
Abstract: The role of mesoscale eddies in the poleward heat transport in the ocean is investigated; in particular, the compensation of poleward eddy heat transport by an eddy-induced mean meridional circulation is examined. A ...
Ring Genesis and the Related Heat Transport. Part II: A Model Comparison
Publisher: American Meteorological Society
Abstract: Various ocean circulation models have been compared with respect to their performance in the genesis of rings and the subsequent heat transport. Emphasis has been placed on the role of the spurious diapycnal fluxes of heat ...
Eddy Mixing of Potential Vorticity versus Thickness in an Isopycnic Ocean Model
Publisher: American Meteorological Society
Abstract: Parameterizations of the eddy-induced velocity that advects tracers in addition to the Eulerian mean flow are traditionally expressed as a downgradient Fickian diffusion of either isopycnal layer thickness or large-scale ...
The Zonal Dimension of the Indian Ocean Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: The three-dimensional structure of the meridional overturning circulation (MOC) in the deep Indian Ocean is investigated with an eddy-permitting ocean model. The amplitude of the modeled deep Indian Ocean MOC is 5.6 Sv (1 ...
Eddy-Induced Heat Transport in a Coupled Ocean–Atmospheric Anomaly Model
Publisher: American Meteorological Society
Abstract: The midlatitude meridional heat transport in the ocean can be partitioned into a transport by the mean flow and an eddy transport. This heat transport has been studied in several ocean-only models. Surprisingly, it was ...
Assessing the Roles of Three Eddy Types in Restratifying the Labrador Sea after Deep Convection
Publisher: American Meteorological Society
Abstract: estratification after deep convection is one of the key factors in determining the temporal variability of dense water formation in the Labrador Sea. In the subsurface, it is primarily governed by lateral buoyancy fluxes ...
The Interaction of a Deep Western Boundary Current and the Wind-Driven Gyres as a Cause for Low-Frequency Variability
Publisher: American Meteorological Society
Abstract: Recent modeling and observational studies have indicated that the interaction of the Gulf Stream and the deep western boundary current (DWBC) in the North Atlantic may induce low-frequency (decadal timescale) variability. ...
The Impact of Southern Ocean Sea Ice in a Global Ocean Model
Publisher: American Meteorological Society
Abstract: Most of the Southern Ocean (SO) is marginally stably stratified and thus prone to enhanced convection and possibly bottom-water formation whenever the upper ocean is cooled or made more saline by ice formation. Sea ice ...
A Model Analysis of the Behavior of the Mediterranean Water in the North Atlantic
Publisher: American Meteorological Society
Abstract: The behavior of the Mediterranean Water in the North Atlantic Ocean sector of a global ocean general circulation model is explored, starting from its entry point at the Strait of Gibraltar. The analysis focuses primarily ...
