The Impact of Abyssal Mixing Parameterizations in an Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: A parameterization of vertical diffusivity in ocean general circulation models has been implemented in the ocean model component of the Community Climate System Model (CCSM). The parameterization represents the dynamics ...
Eddy-Driven Recirculations from a Localized Transient Forcing
Publisher: American Meteorological Society
Abstract: he generation of time-mean recirculation gyres from the nonlinear rectification of an oscillatory, spatially localized vorticity forcing is examined analytically and numerically. Insights into the rectification mechanism ...
Forcing and Sampling of Ocean General Circulation Models: Impact of High-Frequency Motions
Publisher: American Meteorological Society
Abstract: Significant inertial oscillations are present in all primitive equation ocean general circulation models when they are forced with high-frequency (period order of days) wind stress fields. At specific latitudes the energy ...
The Oceanic Eddy Heat Transport
Publisher: American Meteorological Society
Abstract: The rectified eddy heat transport is calculated from a global high-resolution ocean general circulation model. The eddy heat transport is found to be strong in the western boundary currents, the Antarctic Circumpolar ...
A Destabilizing Thermohaline Circulation–Atmosphere–Sea Ice Feedback
Publisher: American Meteorological Society
Abstract: Some of the interactions and feedbacks between the atmosphere, thermohaline circulation, and sea ice are illustrated using a simple process model. A simplified version of the annual-mean coupled ocean?atmosphere box model ...
The Arctic Ocean Spices Up
Publisher: American Meteorological Society
Abstract: he contemporary Arctic Ocean differs markedly from midlatitude, ice-free, and relatively warm oceans in the context of density-compensating temperature and salinity variations. These variations are invaluable tracers in ...
On Recirculation Forced by an Unstable Jet
Publisher: American Meteorological Society
Abstract: Previous numerical experiments with an unstable zonal jet on a ? plane are extended to the reduced-gravity case. The strength of the resulting recirculation varies inversely with the combination ? + 1/S where S is the ...
Recirculation Gyres Forced by a Beta-Plane Jet
Publisher: American Meteorological Society
Abstract: A numerical model, with quasigeostrophic and barotropic dynamics, is used to study the forcing of mean flows by an unstable jet. The initially zonal jet has specified shape and transport at the western inflow boundary and ...
Variations of the North Pacific Subtropical Mode Water from Direct Observations
Publisher: American Meteorological Society
Abstract: ooring measurements from the Kuroshio Extension System Study (June 2004?June 2006) and from the ongoing Kuroshio Extension Observatory (June 2004?present) are combined with float measurements of the Argo network to study ...
Satellite-Derived Ocean Thermal Structure for the North Atlantic Hurricane Season
Publisher: American Meteorological Society
Abstract: his paper describes a new model (method) called Satellite-derived North Atlantic Profiles (SNAP) that seeks to provide a high-resolution, near-real-time ocean thermal field to aid tropical cyclone (TC) forecasting. Using ...
