Properties and dynamics of mesoscale eddies in Fram Strait from a comparison between two high-resolution ocean–sea ice models [PDF]

Ocean Science, 2020
Fram Strait, the deepest gateway to the Arctic Ocean, is strongly influenced by eddy dynamics. Here we analyse the output from two eddy-resolving models (ROMS – Regional Ocean Modeling System; FESOM – Finite-Element Sea-ice Ocean Model) with around 1 ...

Barotropic kinetic energy and enstrophy transfers in the atmosphere

Geophysical Research Letters, 2016
The midlatitude atmosphere is characterized by turbulent eddies that act to produce a depth‐independent (barotropic) mean flow. Using the NCEP (National Centers for Environmental Prediction) Reanalysis 2 data, the latitudinal dependence of barotropic ...

Effects of mesoscale eddy/wind interactions on biological new production and eddy kinetic energy [PDF]

Journal of Geophysical Research: Oceans, 2009
Accounting for ocean currents in the bulk parameterization of the wind stress might represent a physically more plausible way to force an ocean model than ignoring their effect. We show in this study that using the air‐sea velocity difference instead of the atmospheric wind in the wind stress formulation dampens both the near‐surface eddy activity and ...

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)

A new dynamic subgrid-scale model using artificial neural network for compressible flow

Theoretical and Applied Mechanics Letters, 2022
The subgrid-scale (SGS) kinetic energy has been used to predict the SGS stress in compressible flow and it was resolved through the SGS kinetic energy transport equation in past studies.

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 ...

Offshore propagation of eddy kinetic energy in the California Current [PDF]

Journal of Geophysical Research: Oceans, 2001
Low‐pass‐filtered velocities obtained from surface drifters and surface geostrophic velocities estimated from TOPEX/Poseidon altimeter data have recently revealed a clear and robust seasonal cycle in the surface eddy kinetic energy (EKE) in the California Current (CC) [Kelly et al., 1998; Strub and James, 2000]. The seasonal cycle begins in spring when

On the Genesis of the South China Sea Mesoscale Eddies

Journal of Marine Science and Engineering, 2022
The climatology of the mesoscale eddies in the upper layer of the South China Sea (SCS) is investigated for an understanding of its genesis using the outputs from a 1/12.5° ocean reanalysis.

Wind work on oceanic mesoscale eddies in the Northeast Tropical Pacific Ocean

Frontiers in Marine Science, 2023
The transfer of atmospheric kinetic energy to the ocean is one of the major concerns in climate research. According to previous studies, the work of wind stress on oceanic mesoscale eddy is negative in most oceans, referred to as “eddy killing”. However,

Atmospheric teleconnection patterns and eddy kinetic energy content: wavelet analysis [PDF]

Nonlinear Processes in Geophysics, 2004
Abstract. In this paper, we employ a non-decimated wavelet decomposition to analyse long-term variations of the teleconnection pattern monthly indices (the North Atlantic Oscillation and the Southern Oscillation) and the relationship of these variations with eddy kinetic energy contents (KE) in the atmosphere of mid-latitudes and tropics.
