RISThe 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 ...
On the Dynamics of the Slope Current System along the West European Margin. Part I: Analytical Calculations and Numerical Simulations with Steady-State Forcing
Publisher: American Meteorological Society
Abstract: The dynamics of the baroclinic slope current system along the western European margin in the Bay of Biscay and along the northern Iberian Peninsula are investigated in two different models, one analytical and one numerical. ...
Impact of Channel Geometry and Rotation on the Trapping of Internal Tides
Publisher: American Meteorological Society
Abstract: The generation and propagation of internal tides has been studied with an isopycnic three-dimensional ocean model. The response of a uniformly stratified sea in a channel, which is forced by a barotropic tide on its open ...
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 ...
On the Dynamics of the Slope Current System along the West European Margin. Part II: Analytical Calculations and Numerical Simulations with Seasonal Forcing
Publisher: American Meteorological Society
Abstract: The seasonality of the baroclinic slope current system along the western European margin in the Bay of Biscay and along the northern Iberian Peninsula is investigated in a joint analysis of an analytical model and numerical ...
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 ...
