Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.

High‐Resolution Observations Unveil (Sub)Mesoscale Heat Fluxes Shaping Upper‐Ocean Heat Content

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Upper‐ocean heat content (UOHC) modulates air–sea exchange in tropical regions; however, its variability at (sub)mesoscale remains insufficiently resolved. Here we combine Surface Water and Ocean Topography (SWOT) observations with high‐resolution glider sections in the northeastern tropical Pacific, where mesoscale eddies and sharp frontal ...

Hydraulic or Seepage Erosion: What Drives Bank Collapse in Tidal Environments?

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The collapse of channel banks in tidal environments has typically been interpreted using fluvial concepts that prioritize hydraulic (flow‐driven) erosion. Yet daily tidal fluctuations trap pore water in channel banks, potentially producing sustained seepage flows capable of triggering collapse even without strong currents.

Exploring the Interior Structure and Mode of Tidal Heating in Enceladus

The Planetary Science Journal
Enceladus is among the most intriguing bodies in the solar system due to its astrobiological potential. Determining the extent and duration of habitability (i.e., sustained habitability ) requires characterizing the interior properties and the level and ...

Turbulent Mixing and Dissipation Around Rough Seamounts

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Seamounts are critical components of the global ocean energy budget, contributing significantly to turbulent dissipation through their interaction with large‐scale flows. However, most previous numerical investigations used smoothed bathymetry that omits small‐scale topographic variability. We use turbulence‐resolving large‐eddy simulations to

A Method for Quantifying Paleoenvironmental Impacts on Lunar Recession and the Moon’s Age

The Astrophysical Journal
Geological evidence indicates that the Moon formed at least 4.46 billion years ago. Models of Earth–Moon evolution generally describe tidal friction as the primary driver of lunar recession—the gradual increase in the lunar orbital semimajor axis—and the

The coupled tidal evolution of the moons and spins of warm exoplanets

Astronomy & Astrophysics
Context. The Solar System giant planets harbor a wide variety of moons. Among them, the largest moons have moon-to-planet mass ratios of the order of 10−4.

Impact of Non‐Classical Gravity‐Wave Dynamics on Middle‐Atmosphere Mean Flow and Solar Tides

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Conventional gravity‐wave (GW) parameterizations neglect three aspects of GW dynamics. Instead of momentum and entropy fluxes they use Eliassen‐Palm fluxes, thereby neglecting the possibility that resolved flow are not in geostrophic and hydrostatic balance.

Quasi‐Stationary Atmospheric Rivers as the Primary Driver of Rossby Wave Activity in the Global Subtropics

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Hovmöller plots of upper‐tropospheric local (Rossby) wave activity (LWA) show that the subtropics of the North Pacific/Atlantic basins are relatively wave‐free in the upstream and wavier in the downstream of quasi‐stationary atmospheric rivers (QSARs).
