A physics-informed machine learning approach for predicting acoustic convergence zone features from limited mesoscale eddy data

Frontiers in Marine Science
Mesoscale eddies are prevalent mesoscale phenomena in the oceans that alter the thermohaline structure of the ocean, significantly impacting acoustic propagation patterns. Accurately predicting acoustic convergence zone features has become an urgent task,

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 ...

Suppression of Mesoscale Eddy Mixing by Topographic PV Gradients [PDF]

Oceanic mesoscale eddy mixing plays a crucial role in Earth’s climate system by redistributing heat, salt, and carbon. For many ocean and climate models, mesoscale eddies still need to be parameterized.

ENSO's Imprint on the Southern Ocean: Wind Waves Drive Surface Cross‐Frontal Flow

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tropical teleconnection associated with El Niño–Southern Oscillation (ENSO) is widely recognized for regulating multiple physical processes in the Southern Ocean. However, despite its influence on Southern Ocean wind patterns, the response of surface flow has received little attention.

Damping of climate-scale oceanic variability by mesoscale eddy turbulence

, 2020
The impact of mesoscale eddy turbulence on long-term, climatic variability in the ocean’s buoyancy structure is investigated using observations from a mooring deployed in the Drake Passage, Southern Ocean. By applying the Temporal-Residual-Mean framework

More Frequent Atmospheric Rivers and Associated Precipitation Extremes Induced by the Baroclinic Annular Mode

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Atmospheric rivers (ARs) play a crucial role in the global hydrological cycle, yet how the intrinsic midlatitude atmospheric variability modulates their activity on subseasonal timescales remains poorly understood. Here, we show that AR frequency and landfall in both hemispheres vary strongly with the strength and phase of the Baroclinic ...

Isopycnal Pathway for Small‐Particle Export in a Decaying Cyclonic Eddy Revealed by a BGC‐Argo Float

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies influence carbon export through production, subduction, mixing, and particle redistribution. In this study, a BGC‐Argo float observed a deep particle layer in the twilight zone during the decay of a cyclonic eddy in the Northwest Pacific.

Incorporation of larval fishes into a developing anti-cyclonic eddy of the Leeuwin Current: timing, sources and pathways [PDF]

, 2009
Meso-scale circulation and cross-shelf transport of planktonic biota associated with the formation of an anticyclonic (warm-core) eddy of the poleward-flowing Leeuwin Current (LC) were examined during a month-long, multidisciplinary voyage off south ...

Asymmetric Particle Aggregation in Ocean Eddies Driven by Eddy‐Wind Interactions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies, prevalent across the global ocean, play a crucial role in the transport and mixing of climate‐sensitive tracers such as heat, salt, and nutrients. While traditional quasi‐geostrophic theory predicts symmetric kinematics and equivalent material transport by cyclonic and anticyclonic eddies, our analysis of satellite altimeter ...
