Future Northeastward Shift of Extratropical Transition of Tropical Cyclones Over the North Atlantic in Downscaling Projections

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tropical cyclones (TCs) often undergo extratropical transition (ET) at the midlatitudes, becoming post‐tropical cyclones (PTCs). We combine a logistic regression PTC identification model with synthetic TC tracks and intensities from the Columbia HAZard model (CHAZ) to project future ET completion over the North Atlantic (NA).

Response of the Southern Hemisphere extratropical cyclone climatology to climate intervention with stratospheric aerosol injection

Environmental Research: Climate
Little is known about how climate intervention through stratospheric aerosol injection (SAI) may affect the climatology of the Southern Hemisphere extratropical cyclones under warming scenarios.

Rectified Effect of Synoptic‐Scale Atmospheric Eddies on Global Ocean‐Atmosphere Heat Exchanges

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Midlatitude oceans are characterized by vigorous turbulent heat flux (THF) from the ocean to the atmosphere. While the influence of sub‐weekly, synoptic‐scale atmospheric eddies on short‐term THF variability is well‐documented, their long‐term, “rectified” effect on air‐sea interactions remains poorly understood.

Using satellite data and reanalysis to evaluate the representation of diabatic processes in extratropical cyclones in a climate model

, 2016
Extratropical cyclones are a key feature of the weather in the extra-tropics, which climate models need to represent in order to provide reliable projections of future climate.

Tropical cyclone intensification and extratropical transition under alternate climate conditions: a case study of Hurricane Ophelia (2017) [PDF]

Weather and Climate Dynamics
Post-tropical cyclones can have substantial impacts on regions unaccustomed to such powerful storms. Previous studies have found that the prevalence of such storms is expected to increase in the future.

How Can the MJO's Planetary Scale Kelvin Wave and Synoptic Kelvin Waves Move at Different Phase Speeds in the Same Large‐Scale Environment?

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Equatorially trapped Kelvin waves can occur through the depth of the troposphere and beyond. Previous works have demonstrated that these waves respond profoundly to the background flows through which they propagate, leading to variation in phase speed and dispersion characteristics. Vertical variation in the background flow might allow for the

More Frequent Atmospheric Rivers and Associated Precipitation Extremes Induced by the Baroclinic Annular Mode

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Atmospheric rivers (ARs) play a crucial role in the global hydrological cycle, yet how the intrinsic midlatitude atmospheric variability modulates their activity on subseasonal timescales remains poorly understood. Here, we show that AR frequency and landfall in both hemispheres vary strongly with the strength and phase of the Baroclinic ...

Environmental characteristics associated with the development of deep warm core Mediterranean Cyclones [PDF]

Weather and Climate Dynamics
Cyclonic perturbations in the Mediterranean region sometimes acquire characteristics typical of tropical cyclones, such as a deep inner warm core. In these cases, they become very intense structures that can cause large precipitations and significant ...

Diagnosing the Influence of Southern Ocean Storms on Air‐Sea Carbon Dioxide Flux From Synthetic Floats: A Modeling Study

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Southern Ocean is the stormiest place on Earth, but sparse observations challenge our ability to understand the influence of storms on air‐sea CO2 $\mathrm{C}{\mathrm{O}}_{\mathrm{2}}$ fluxes. Here we quantify storm‐driven Southern Ocean CO2 $\mathrm{C}{\mathrm{O}}_{\mathrm{2}}$ fluxes using synthetic floats that mimic real‐world platforms
