Vertical Eddy Fluxes in the Southern Ocean

Journal of Physical Oceanography (2012)

Jan D. Zika Julien Le Sommer Carolina O. Dufour Jean‐Marc Molines Bernard Barnier

Abstract The overturning circulation of the Southern Ocean has been investigated using eddying coupled ocean–sea ice models. The circulation is diagnosed in both density–latitude coordinates and in depth–density coordinates. Depth–density coordinates follow streamlines where the Antarctic Circumpolar Current is equivalent barotropic, capture the descent of Antarctic Bottom Water, follow density outcrops at the surface, and can be interpreted energetically. In density–latitude coordinates, wind-driven northward transport of light water and southward transport of dense water are compensated by standing meanders and to a lesser degree by transient eddies, consistent with previous results. In depth–density coordinates, however, wind-driven upwelling of dense water and downwelling of light water are compensated more strongly by transient eddy fluxes than fluxes because of standing meanders. Model realizations are discussed where the wind pattern of the southern annular mode is amplified. In density–latitude coordinates, meridional fluxes because of transient eddies can increase to counter changes in Ekman transport and decrease in response to changes in the standing meanders. In depth–density coordinates, vertical fluxes because of transient eddies directly counter changes in Ekman pumping.

Eddy contributions to the meridional transport of salt in the North Atlantic

Journal of Geophysical Research Atmospheres (2012)

Anne‐Marie Tréguier Julie Deshayes Camille Lique Raphaël Dussin J. M. Molines

The meridional transport of salt in the Atlantic ocean is an important process for climate, controlling the stability of the meridional overturning circulation. The contribution of transient eddies to this transport is quantified in an eddy resolving North Atlantic model at 1/12° resolution (NATL12), and compared with lower resolution North‐Atlantic and global 1/4° models. In NATL12 between 10°N and 40°N, there is a volume loss by evaporation of 0.6 Sverdrups (Sv). The divergence of the eddy flux of salt (normalized by a reference salinity of 34.8) is 0.2 Sv over the region, a significant fraction of the total air‐seawater exchange, but it is compensated by an opposite convergent transport of salt by the mean flow, so that the total transport of salt is small. The compensation between eddy and mean salt transport is almost complete in a multicentury long global model experiment, but less effective in NATL12 because the short integration time does not allow the salt content to equilibrate and the model drift is large. Eddies arising from baroclinic instability contribute to the meridional salt transports at the northern and southern boundary of the subtropical gyre, where they appear consistent with a lateral diffusion acting on the mean salinity gradient. However, the eddy transport of salt is the sum of two terms: an advective contribution (arising from the correlations of velocity and isopycnal thicknesses) and a diffusion along isopycnals. Both components have the same amplitude at the southern boundary of the subtropical gyre, while diffusion is dominant at the northern boundary.

NOAA-GFDL GFDL-ESM4 CMIP6 CMIP additional model output

Zenodo (CERN European Organization for Nuclear Research) (2021)

John P. Krasting Jasmin G. John Chris Blanton Colleen McHugh S. V. Nikonov

This repository contains annual 3D sea water age since surface contact files from a subset of simulations with GFDL's ESM4.1 climate model (Dunne et al., 2020) that were contributed to the 6th Coupled Model Intercomparison Project (CMIP6). Both the ocean model native grid and the regridded output can be found in this repository. For the regridded output, the files have been regridded from MOM6 native grid to standard World Ocean Atlas 1x1 horizontal grid, and they have been remapped from the lagrangian vertical coordinate used by GFDL's MOM6 ocean model (Adcroft et al., 2019) to standard World Ocean Atlas depths. Files have undergone QA/QC. All data files are NetCDF. Enquiries should be directed to Jasmin.John (Jasmin.John@noaa.gov) or John Dunne (John.Dunne@noaa.gov) Anyone using these data should cite Dunne et al. (2020) and Adcroft et al. (2019). See references below. Other variables associated with these simulations, along with assigned DOI's, are available through the ESGF CMIP6 portal:https://esgf-node.llnl.gov/projects/cmip6/ ______________________________________________________________________ The tar files in the repository follow this naming convention: <model>_<activity>_<MIP>_<experiment>_<component_and_grid>_<variable>.tar.gz E.g.
