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,

Mesoscale Ocean Eddy-Wind Interaction

, 2022
A surface wind stress that includes the ocean surface current (known as relative wind stress) can result in a damping of eddy energy. A weakened eddy field has significant implications for the regional and global ocean circulation. Eddy energy budget-based parameterisations currently employ an arbitrary dissipation rate, leaving some uncertainty in ...

Simulating Shallow Mesoscale Overturning Circulations in the Trades With Kilometer‐Scale Earth System Models

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Shallow mesoscale overturning circulations (SMOCs) are ubiquitous in the trades, primarily triggered by mesoscale convective heating and influencing the organization of shallow cumuli. Accurate representation of SMOCs and their co‐variability with moisture is crucial for capturing mesoscale cloud organization in models and improving climate ...

Coherent water transport across the South Atlantic

, 2015
The role of mesoscale eddies in transporting Agulhas leakage is investigated using a recent technique from nonlinear dynamical systems theory applied on geostrophic currents inferred from the over two-decade-long satellite altimetry record.

Balanced to Unbalanced Motions at a Submesoscale Front and Energy Transfer From Eddy Splitting

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Submesoscale dynamics play a crucial role in energy redistribution in the upper ocean but remain challenging to observe due to their small spatial and temporal scales. We use ship‐based observations of an oceanic submesoscale front sampled at high resolution while repeatedly traversed to observe deformation and splitting of an embedded ...

Sampling strategies and four-dimensional assimilation of altimetric data for ocean monitoring and prediction [PDF]

, 1984
Numerical experiments using simulated altimeter data were conducted in order to examine the assimilation of altimeter-derived sea surface heights into numerical ocean circulation models. A reduced-gravity, primitive equation circulation model of the Gulf

Evidence for a k^{-5/3} spectrum from the EOLE Lagrangian balloons in the low stratosphere

, 2003
The EOLE Experiment is revisited to study turbulent processes in the lower stratosphere circulation from a Lagrangian viewpoint and resolve a discrepancy on the slope of the atmospheric energy spectrum between the work of Morel and Larcheveque (1974) and

Changes in the Westward Transport of Saharan Dust From West Africa With Anthropogenic Forcing in the WRF Model

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large uncertainties exist for future westward Saharan dust transport with increasing Greenhouse Gas emissions. We evaluate future changes in westward dust transport at the longitude of 18.6°W and a latitude range of 4°N–30°N using the Weather Research and Forecasting Model (WRF) with the GOCART dust module for the present‐day, with ERA‐Interim

Coherent Lagrangian vortices: The black holes of turbulence

, 2013
We introduce a simple variational principle for coherent material vortices in two-dimensional turbulence. Vortex boundaries are sought as closed stationary curves of the averaged Lagrangian strain.
