The eddy kinetic energy budget in the Red Sea [PDF]
Journal of Geophysical Research: Oceans, 2016 AbstractThe budget of eddy kinetic energy (EKE) in the Red Sea, including the sources, redistributions, and sink, is examined using a high'resolution eddy‐resolving ocean circulation model. A pronounced seasonally varying EKE is identified, with its maximum intensity occurring in winter, and the strongest EKE is captured mainly in the central and ...

Geophysical Research Letters, 2022 AbstractThe performance of eddy‐resolving global ocean–sea ice models in simulating mesoscale eddies is evaluated using six eddy‐resolving experiments forced by different atmospheric reanalysis products. Interestingly, eddy‐resolving ocean general circulation models (OGCMs) tend to simulate more (less) energetic eddy‐rich (eddy‐poor) regions with a ...

Interannual Eddy Kinetic Energy Modulations in the Agulhas Return Current [PDF]
Journal of Geophysical Research: Oceans, 2018 AbstractInterannual variability in the mesoscale eddy field in the Agulhas Return Current (ARC) of 32–42°S and 15–35°E is investigated based on satellite altimeter observations and state estimate from the Estimating the Circulation and Climate of the Ocean, Phase II from 1993 to 2016.

Frontiers in Marine Science, 2022 The three-dimensional structure of a supercharged cold eddy, which showed strong temperature anomaly, was continuously investigated for 83 days based on current- and pressure-equipped inverted echo sounder observations in the Kuroshio Extension region ...

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 ...

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.

Production and destruction of eddy kinetic energy in forced submesoscale eddy-resolving simulations [PDF]
Ocean Modelling, 2016 Abstract We study the production and dissipation of the eddy kinetic energy (EKE) in a submesoscale eddy field forced with downfront winds using the Process Study Ocean Model (PSOM) with a horizontal grid resolution of 0.5 km. We simulate an idealized 100 m deep mixed-layer front initially in geostrophic balance with a jet in a domain that permits ...

The Lorenz energy cycle: trends and the impact of modes of climate variability
Tellus: Series A, Dynamic Meteorology and Oceanography, 2021 The atmospheric circulation is driven by heat transport from the tropics to the polar regions, embedding energy conversions between available potential and kinetic energy through various mechanisms.

The Impact of Horizontal Resolution on Energy Transfers in Global Ocean Models
Fluids, 2017 The ocean is a turbulent fluid with processes acting on a variety of spatio-temporal scales. The estimates of energy fluxes between length scales allows us to understand how the mean flow is maintained as well as how mesoscale eddies are formed and ...
