Large eddy simulation of ocean mesoscale eddies

Mesoscale eddies produce lateral (2D) fluxes that need to be parameterized in eddy-permitting (1/4-degree) global ocean models due to insufficient horizontal resolution. Here, we systematically apply methods from the 3D LES community to parameterize lateral vorticity fluxes produced by mesoscale eddies leveraging an explicit filtering approach together

Application of Variational Autoencoder‐Based Clustering for Geophysical Fluid Circulations With Small Sample Size

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract The variational autoencoder (VAE), a deep generative model, can extract a good feature representation for clustering from complex data; however, the use of this algorithm in the geophysical fluid circulation has been limited. The sample size for a geophysical phenomenon is generally small because of a large dimensional size, especially for ...

Internal Lee Waves Control Deep Ocean Turbulent Mixing in the Antarctic Circumpolar Current at 50°E

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Full‐depth (Surface‐to‐bottom) turbulent kinetic energy dissipation (TKED) observed with fast‐response thermistors across the Antarctic Circumpolar Current (ACC) at 50° $\mathit{{}^{\circ}}$E is compared with the energy flux of bottom‐generated internal waves estimated with high‐resolution multibeam bathymetry.

On the interplay between downwelling, deep convection and mesoscale eddies in the Labrador Sea

Ocean Modelling, 2019
In this study, an idealized eddy-resolving model is employed to examine the interplay between the downwelling, ocean convection and mesoscale eddies in the Labrador Sea and the spreading of dense water masses.

Contribution of Unconventional Mesoscale Eddies to Surface Poleward Heat Flux in the Southern Ocean Over the Past Three Decades

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Mesoscale eddies play a key role in transporting heat poleward across the Antarctic Circumpolar Current (ACC). In addition to conventional eddies (warm‐core anticyclones and cold‐core cyclones), recent studies have detected a significant number of unconventional eddies at the surface (cold‐core anticyclones and warm‐core cyclones).

Temperature Structure Inversion of Mesoscale Eddies in the South China Sea Based on Deep Learning

Journal of Marine Science and Engineering
Mesoscale eddies are common in global oceans, playing crucial roles in ocean dynamics, ocean circulation, and heat transport, and their vertical structures can affect the water layers from tens to thousands of meters.

Complexity of Mesoscale Eddy Diffusivity in the Ocean

Geophysical Research Letters, 2020
Abstract Stirring of water by mesoscale currents (“eddies”) leads to large‐scale transport of many important oceanic properties (“tracers”). These eddy‐induced transports can be related to the large‐scale tracer gradients, using the concept of turbulent diffusion.

Oceanic Eddy Modulation of Wintertime Air‐Sea Coupling and Marine Atmospheric Boundary Layer Winds Over the East China Sea

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract This study examined the effects of air‐sea coupling and oceanic mesoscale eddies on wintertime low‐level wind events within the marine atmospheric boundary layer (MABL) over the Kuroshio front zone in the East China Sea. High‐resolution (eddy‐resolving, 5 km) and low‐resolution (50 km) simulations were conducted using prescribed sea surface ...
