Estimating the Geostrophic–Ageostrophic Transition Scale in Ocean Currents From Wind Generated Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract SWOT resolves sea surface height at spatial scales where geostrophic balance may break down and ageostrophic motions become significant, making identification of the transition scale essential. We test whether wind generated waves provide an independent diagnostic of this transition.

Rough Topography and Fast Baroclinic Rossby Waves

Geophysical Research Letters
Oceanographic observations have revealed that basin‐scale Rossby waves can travel at speeds systematically exceeding values predicted by linear theory based on the flat‐bottom approximation.

Modulation of Stratosphere‐to‐Troposphere Transport of Ozone by North Pacific Weather Patterns

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Stratosphere‐to‐troposphere transport (STT) of ozone is a major natural source of tropospheric ozone and is tightly linked to both stratospheric and tropospheric circulations. However, the complex interactions of drivers make it challenging to understand the subseasonal variability of STT.

Rapid Surface Intensification of the Gulf Stream Since 2014

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The warm, swift Gulf Stream (GS) plays a key role in shaping weather and climate patterns across the North Atlantic. Using 31‐year (1993–2023) of continuous satellite altimeter observations, we identify a pronounced intensification of the free‐flowing GS after its separation from the coast beginning around 2014 and persisting thereafter ...

Satellite Altimetry Reveals an Eddy Train Along the Ross Sea Shelf Break

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Oceanic circulation along the Antarctic shelf break regulates heat and material exchanges between the continental shelf and the open ocean, playing a crucial role in ice shelf melting and global overturning circulation. However, the circulation remains poorly understood due to limited observations.

Tropical Eastern Pacific Decadal Variability Drives Atlantic Multidecadal Variability: Two Distinct Pathways

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Using a tropical Pacific pacemaker experiment, we demonstrate that the tropical eastern Pacific (TEP) decadal sea surface temperature (SST) variability influences the Atlantic Multidecadal Variability (AMV) through two pathways. The TEP induces a North Atlantic SST tripole response that peaks 1 year later, primarily via modulation of net ...

Process-oriented evaluation of quasi-stationary Rossby waves and their impact on surface air temperature extremes in dynamical downscaling over North America [PDF]

Geoscientific Model Development
Quasi-stationary Rossby waves are a crucial component of the general circulation and play a significant role in regional water and energy cycles, as well as in extreme events.

High‐ and Low‐Concentration Spiral Chlorophyll Bands Excited by Vortex Rossby Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract High‐concentration spiral chlorophyll bands (HSCBs) embedded in oceanic mesoscale eddies have recently been observed worldwide. They are considered to be the footprints of vortex Rossby waves (VRWs). Based on satellite observations and drifter data, we identified additional low‐concentration spiral chlorophyll bands (LSCBs).

Predictability of midlatitude Rossby‐wave packets

Quarterly Journal of the Royal Meteorological Society
Abstract Rossby‐wave packets (RWPs) along the midlatitude jet are a fundamental ingredient of extratropical dynamics. RWPs have been linked to enhanced atmospheric predictability and the occurrence of extreme weather events. We here investigate the predictability of Northern Hemispheric RWPs as physical entities, defined by enhanced ...
