Global coarse-grained mesoscale eddy statistics based on integrated kinetic energy and enstrophy correlations [PDF]

Ocean Science, 2022
Recently, Jánosi et al. (2019) introduced the concept of a “vortex proxy” based on an observation of strong correlations between integrated kinetic energy and integrated enstrophy over a large enough surface area.

Mean Kinetic Energy and its Projected Changes Dominate over Eddy Kinetic Energy in the Arctic Ocean [PDF]

Geophysical Research Letters
Abstract As sea ice retreats in a warming climate, the Arctic Ocean is becoming more energetic; yet little is known about this additional energy's distribution in the water column. We use a high‐resolution (3–4 km) pan‐Arctic ocean‐sea ice model forced by present day and future scenarios to examine changes in mean kinetic energy (MKE)

Diagnostic Framework Linking Eddy Flux Ellipse with Eddy-Mean Energy Exchange

Ocean-Land-Atmosphere Research
The design of non-eddy-resolving numerical models requires a good understanding and an appropriate representation of the eddy-mean flow feedback. To understand this feedback, we propose a diagnostic framework that links eddy geometry with the eddy-mean ...

The Multi‐Scale Response of the Eddy Kinetic Energy and Transport to Strengthened Westerlies in an Idealized Antarctic Circumpolar Current

Geophysical Research Letters
The Southern Ocean's eddy response to changing climate remains unclear, with observations suggesting non‐monotonic changes in eddy kinetic energy (EKE) across scales.

Eddy Kinetic Energy in the Arctic Ocean From a Global Simulation With a 1‐km Arctic [PDF]

Geophysical Research Letters, 2020
Simulating Arctic Ocean mesoscale eddies in ocean circulation models presents a great challenge because of their small size. This study employs an unstructured‐mesh ocean‐sea ice model to conduct a decadal‐scale global simulation with a 1‐km Arctic.

Dissipation of mesoscale eddies at a western boundary via a direct energy cascade

Scientific Reports, 2022
The fate of mesoscale eddy kinetic energy represents a large source of uncertainty in the global ocean energy budget. Satellite altimetry suggests that mesoscale eddies vanish at ocean western boundaries.

The Dissipation of Kinetic Energy in the Lofoten Basin Eddy [PDF]

Journal of Physical Oceanography, 2018
AbstractOcean microstructure, current, and hydrography observations from June 2016 are used to characterize the turbulence structure of the Lofoten Basin eddy (LBE), a long-lived anticyclone in the Norwegian Sea. The LBE had an azimuthal peak velocity of 0.8 m s−1 at 950-m depth and 22-km radial distance from its center and a core relative vorticity ...

Contribution of mesoscale eddies to energy of the Lofoten Basin

Russian Journal of Earth Sciences, 2022
A comparative assessment of the contribution of eddies and other dynamic structures to the energy of the Lofoten Basin is carried out. The basis of the study is the data of global ocean reanalysis GLORYS12V1 for 1993–2019.

Sources of Eddy Kinetic Energy in the Labrador Sea [PDF]

Journal of Physical Oceanography, 2002
Experiments with a suite of North Atlantic general circulation models are used to examine the sources of eddy kinetic energy (EKE) in the Labrador Sea. A high-resolution model version (112°) quantitatively reproduces the observed signature. A particular feature of the EKE in the Labrador Sea is its pronounced seasonal cycle, with a maximum intensity in
