Long‐Lived Anticyclonic Eddies Facilitate Convection in the Greenland Sea Over Multiple Consecutive Winters

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wintertime open‐ocean convection is a key process in renewing deep water; however, the processes that promote convection on local scale remain poorly understood. We investigate the role of long‐lived anticyclonic eddies in facilitating deep convection in the Greenland Sea using a new model simulation and observations.

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-

Tracking control of underwater gliders in ocean mesoscale eddies observation task

, 2016
Transports of heat, fresh water and other things in the ocean have huge effect on the globe climate and resource distribution. Mesoscale eddies play such an important role in the transport process that many researchers want to study the interior ...

Formation of Shallow Cumulus Patterns Using a Simple Warm Cloud Precipitation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A simple model based on predator‐prey‐like dynamics using a system of four nonlinear ordinary differential equations is used to simulate the life cycle of shallow cumulus. By coupling this model across a two‐dimensional array and varying the cloud environment, we can simulate three common patterns of self‐aggregation seen in the maritime ...

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.

GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...

Quantifying the Role of Mesoscale-Driven Processes of Nitrate Supply Within an Iceland Basin Eddy Dipole

, 2011
This study quantitatively assesses the mesoscale spatial variability in local nitrate transport and the net nitrate flux associated with an open ocean eddy dipole, using novel data from the SUV?6 ultra?violet (UV) nitrate sensor integrated with SeaSoar ...

Mechanisms for Meridional Propagation of Global Mesoscale Ocean Eddies Within a PV‐Based Dynamic Framework

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Mesoscale eddies are crucial for global heat and tracer transport, yet the mechanisms underlying their meridional movement remain unclear. Here, we combine satellite observations, idealized numerical experiments, and theoretical modeling to investigate these mechanisms. We demonstrate that the meridional eddy movement is strongly linked to the

The decay of cyclonic eddies by Rossby wave radiation

, 1998
It is argued that because shallow water cyclones on a β-plane drift westward at a speed equal to an available Rossby wave phase speed, they must radiate energy and cannot, therefore, be steady. The form of the Rossby wave wake accompanying a quasi-steady

Intensification of Eddy Energetics Modulates Seasonal Trends and Spatial Variability in the East Australian Current System

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The East Australian Current (EAC) separates near 32°S, forming large, energetic eddies. While the seasonal cycle of the EAC system is well documented, the season‐specific long‐term trends in its separation latitude, eddy energetics, and their spatial heterogeneity remain poorly understood.
