The Role of Eddies in Determining the Structure and Response of the Wind-Driven Southern Hemisphere Overturning: Results from the Modeling Eddies in the Southern Ocean (MESO) Project
The Modeling Eddies in the Southern Ocean (MESO) project uses numerical sensitivity studies to examine the role played by Southern Ocean winds and eddies in determining the density structure of the global ocean and the magnitude and structure of the global overturning circulation. A hemispheric isopycnal-coordinate ocean model (which avoids numerical diapycnal diffusion) with realistic geometry...
متن کاملThe Southern Ocean Overturning: Parameterized versus Permitted Eddies
Four versions of the same global climate model, with horizontal resolution ranging from 1.88 3 3.68 to 0.28 3 0.48, are employed to evaluate the resolution dependence of the Southern Ocean meridional overturning circulation. At coarse resolutions North Atlantic Deep Water tends to upwell diabatically at low latitudes, so that the Southern Ocean is weakly coupled with the rest of the ocean. As r...
متن کاملDeep mesoscale eddies in the Canada Basin, Arctic Ocean
[1] Numerous eddies have been identified in a seven year time series of mooring observations in the Canada Basin, Arctic Ocean. We focus on a series of deep eddies centered at 1200 m depth, and occupying up to 1500 m of the water column. The deep eddies are found to be spatially localized, only ever being observed at one of four mooring sites of the Beaufort Gyre Observing System in the Canada ...
متن کاملComments on Eddies, Mixing and the Large-Scale Ocean Circulation
Some recent laboratory and numerical studies of idealized ocean gyres and circumpolar currents are reviewed in the context of what they might tell us about the relative role of eddy transfer and mixing in setting the structure of the large-scale ocean circulation.
متن کاملUniversal structure of mesoscale eddies in the ocean
[1] Mesoscale eddies dominate oceanic kinetic energy at sub-inertial frequencies. Their three-dimensional structure has, however, remained obscure, hindering better understanding of eddy dynamics. Here by applying the composite analysis of satellite altimetry and Argo float data to the globe, we show that despite remarkable regional differences in amplitude, extent and polarity, etc., mesoscale...
