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 ...

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

Mesoscale ageostrophic circulations associated with baroclinic jet streaks [PDF]

, 1984
Studies of ageostrophic motion attending jet streaks and convection are examined. Various types of dynamical experiments are carried out with the hybrid isentropic-sigma coordinate model. The effects of vorticity and static stability distributions on the

Revisiting Intrinsic Predictability of Wave‐Convection Coupled Bands Over Southern China: Variable and Scale‐Dependent Error Growth Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the variable‐ and scale‐dependent intrinsic predictability of wave‐convection coupled bands over southern China on 30 January 2018, using 1‐km simulations under varying initial moisture conditions. The predictability time is quantified via the Loss Predictability Index (LPI), defined as the ratio of the forecast error ...

Response of the thermohaline front and associated submesoscale features in the Korea Strait to wind variation during autumn

Frontiers in Marine Science
In the present study, a three-dimensional numerical simulation with a 1 km grid spacing is conducted to investigate the response of the thermohaline front in the northern Korea Strait (KS) and its associated submesoscale features to wind variation.

Meridional Dipole in Eddy Activity Along Peruvian Coast During Eastern Pacific El Niño Events

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale oceanic eddies (O $O$(100)km) play a key role in regulating climate by affecting the transport of heat and water mass properties. However, most climate models struggle to simulate these eddies due to coarse horizontal resolution. Using a 120‐year ultra‐high‐resolution simulation with 1/10° ${}^{\circ}$ horizontal ocean resolution ...

Network Divergence Reveals Predictable Pathways of Extreme Rainfall in Central India

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Extreme rainfall events over Central India have increased, reflecting intensified monsoon precipitation driven by factors like urbanization and land use change. With projections indicating further intensification and flood vulnerability, better prediction is critical.
