The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Characterising global ocean mesoscale eddy by AVISO and Haiyang-2 altimeter

International Journal of Digital Earth
This work compares the Haiyang-2 (HY-2) altimeter data with the well-recognized satellite oceanographic data (AVISO) product in the global ocean in their capability of detecting mesoscale eddy. A well-established method to detect mesoscale eddies from HY-

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.

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 ...

Numerical Models, Observing Systems, and Data Assimilation for Prediction of Ocean Mesoscale Eddies

Ocean-Land-Atmosphere Research
Mesoscale eddies pervade the global ocean, characterized by a typical horizontal scale of approximately 100 km and a timescale on the order of a month.

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 ...

An Orthogonal Geometry-Based Algorithm for Accurate Mesoscale Eddy Detection

Journal of Marine Science and Engineering
This article introduces a mesoscale eddy detection algorithm that employs orthogonal transformations of flow field data, and subsequently, for simplicity, it is abbreviated as the OG algorithm.

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 ...

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

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
