Multi-nest high-resolution model of submesoscale circulation features in the Gulf of Taranto [PDF]

, 2017
Recent oceanographic field measurements and high-resolution numerical modelling studies have revealed intense, transient, submesoscale motions characterised by a horizontal length scale of 100 - 10,000 m.

Deep learning detection of submesoscale eddies from MODIS SST in the South China Sea

GIScience & Remote Sensing
Submesoscale eddies play crucial roles in oceanic energy cascades and material transport; however, their detection faces substantial challenges owing to inadequate spatial resolution in traditional satellite altimetric measurements.

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...

Shallow Cumulus Cloud Statistics in Real‐Case Large‐Eddy Simulations and Their Dependence on Soil Moisture

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract The ability of weather and climate models to reproduce the statistical properties of shallow cumulus clouds (SCCs) is critical for representing boundary‐layer transport, cloud cover, and cloud‐radiative effects. This study investigates statistical properties of SCC ensembles using the Icosahedral Nonhydrostatic model in large‐eddy simulation ...

Interannual to Decadal Variations of Submesoscale Motions around the North Pacific Subtropical Countercurrent

Fluids, 2020
The outputs from a submesoscale permitting hindcast simulation from 1990 to 2016 are used to investigate the interannual to decadal variations of submesoscale motions.

Basin‐Scale Marine Heatwave Types in the Gulf of Mexico: Wind–Humidity Controls on Latent Heat‐Loss Suppression and Ocean‐State Modulation of Vertical Thermal Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) in the Gulf of Mexico (GoM) have become more frequent and intense, yet the mechanisms governing basin‐scale events remain incompletely understood. EOF–k‐means clustering of event‐mean sea surface temperature anomalies (SSTA) during 1982–2024 identifies four recurrent, seasonally dependent spatial regimes: two stronger ...

Multi-scale eddy identification and analysis based on deep learning method and ocean color data

International Journal of Digital Earth
Oceanic eddies are ubiquitous phenomena that facilitate the horizontal and vertical transportation of substances under the combination of ocean currents and the Coriolis force, thus they are crucial for the regulation of marine ecosystems.

Eddy characteristics in the northern South China Sea as inferred from Lagrangian drifter data [PDF]

Ocean Science, 2011
Cyclonic and anticyclonic eddies from large scale to submesoscale in the northern South China Sea (NSCS) have been statistically characterized based on the satellite-tracked Lagrangian drifters using our developed geometric eddy identification method ...

Boundary‐Aware Separation of Vortical and Wavy Motions in the Ocean

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract With the recent popularity of the tide‐resolving and submesoscale‐admitting numerical simulations, there is an increasing interest in separating vortical and wavy motions in the ocean. The recently‐proposed dynamics‐based decomposition exploits the relative magnitude of the relative vorticity and horizontal divergence in Fourier space and ...
