Compact Mesoscale Eddies in the South Brazil Bight

Remote Sensing, 2022
Recent studies suggest that the South Brazil Bight (SBB) hosts strong westward propagating mesoscale eddies. We use 28 years of satellite altimetry data and a new Eddy Atlas to estimate how much of the eddy kinetic energy (EKE) observed in the SBB is accounted for by local eddies, generated in the Brazil Current (BC) region, versus remote eddies ...

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Specialized SWOT SSH Data Assimilation Improves the Representation of Multiscale Variability in the Ocean Model

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides wide‐swath sea surface height (SSH) observations at scales poorly sampled by conventional altimetry. Assimilating SWOT data remains challenging because part of the short‐wavelength variance may not be dynamically representable by a given model configuration.

Influence of bottom topography on integral constraints in zonal flows with parameterized potential vorticity fluxes [PDF]

, 2013
An integral constraint for eddy fluxes of potential vorticity (PV), corresponding to global momentum conservation, is applied to two-layer zonal quasi-geostrophic channel flow. This constraint must be satisfied for any type of parameterization of eddy PV

Moisture Aggregation and the Cloud Transition Zone Shape Mesoscale Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Mesoscale moisture aggregation and cloud organization in shallow convection have gained much attention regarding their role in Earth's energy budget and cloud feedbacks on climate. Because aerosol particles swell in humid air, mesoscale moisture patterns are expected to be accompanied by corresponding variations in aerosol optical depth (AOD).

Mesoscale eddies transport deep-sea sediments [PDF]

Scientific Reports, 2014
Mesoscale eddies, which contribute to long-distance water mass transport and biogeochemical budget in the upper ocean, have recently been taken into assessment of the deep-sea hydrodynamic variability. However, how such eddies influence sediment movement in the deepwater environment has not been explored.

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Impacts of Mesoscale Eddy Structural Characteristics on Matched-Field Localization Uncertainty

Sensors
Matched-field processing localizes underwater acoustic targets by measuring the degree of correlation between the acoustic field and replica fields. The intrusion of mesoscale eddies can induce sound speed mismatch in the matched-field process. Therefore,

Global Estimation of the Eddy Kinetic Energy Dissipation From a Diagnostic Energy Balance

Geophysical Research Letters, 2023
Mesoscale eddies dominate the ocean kinetic energy reservoir. However, how and where this energy flows out from the mesoscale remains uncertain. Here, a simplified mesoscale energy budget is used where sources due to baroclinic instability are balanced ...
