Global Estimation of Subsurface Eddy Kinetic Energy of Mesoscale Eddies Using Machine Learning
Journal of Geophysical Research: Machine Learning and ComputationAbstractOceanic eddy kinetic energy (EKE) is a key quantity for measuring the intensity of mesoscale eddies and developing mesoscale eddy parameterizations in ocean circulation models. Three decades of satellite observations enable a global assessment of sea surface EKE.

Geoscience Letters, 2020 The surface ocean current’s imprint on the wind stress (known as the current feedback) has a significant influence on the wind power input to the ocean. In this study, we investigate the effect of the current feedback on mesoscale eddy energetics in the ...

Toward an Energetically Consistent, Resolution Aware Parameterization of Ocean Mesoscale Eddies
Journal of Advances in Modeling Earth Systems, 2019 A subgrid‐scale eddy parameterization is developed, which makes use of an explicit eddy kinetic energy budget and can be applied at both “non‐eddying” and “eddy‐permitting” resolutions.

Observation of Near-Inertial Oscillation in an Anticyclonic Eddy in the Northern South China Sea
Journal of Marine Science and EngineeringAnticyclonic mesoscale eddies are known to trap and modulate near-inertial kinetic energy (NIKE); however, the spatial distribution of NIKE within the eddy core and periphery, as well as the mechanisms driving its energy cascade to smaller scales ...

Eddy Kinetic Energy in the Arctic Ocean From a Global Simulation With a 1‐km Arctic
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.

On atmospheric zonal to eddy kinetic energy exchange for January 1963
Tellus A: Dynamic Meteorology and Oceanography, 1967 An estimate of the exchange of kinetic energy between the large-scale atmospheric eddies and the zonal flow for January 1963 for the troposphere north of 20°N latitude has been made by means of a quasigeostrophic method. This more complete result is compared with the anomalous one obtained earlier by WIIN-NIELSEN, BROWN and DRAKE (1964).
