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).

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.

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

Mediterranean cyclones are a substantial cause of damaging floods in Corsica

Communications Earth & Environment
Cyclones, whether tropical, extratropical, or of Mediterranean origin, play a crucial role in the Earth’s climate system, affecting environments and populations through strong winds, heavy rainfall, and flooding.

A Comparison of Southern Hemisphere Cyclone Track Climatology and Interannual Variability in Coarse-Gridded Reanalysis Datasets

Advances in Meteorology, 2013
Southern Hemisphere (SH) extratropical cyclones have received less study than their Northern Hemisphere (NH) counterparts. Generating SH cyclone tracks from global reanalysis datasets is problematic due to data reliability, especially prior to 1979.

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 ...

Impact of Wind Forcing Resolution on Modeled Wave Extremes at the Coastal Boundary

Geophysical Research Letters
Accurate wind forcing is essential for modeling extreme wave conditions. This study evaluates how wind resolution influences the representation of maximum wind speeds and the simulation of maximum significant wave heights across two cyclone environments:

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

Decadal Sea Level Variability Along the U.S. East Coast: Roles of Extratropical Versus Tropical Climate Modes Over the North Atlantic Ocean

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Coastal decadal sea level anomalies (SLAs) in the U.S. east coast (USEC) play a critical role in modulating coastal flooding frequency, yet relative influences of tropical versus extratropical climate modes over the North Atlantic remain unresolved.

Sub‐Seasonal Forecasting of Precipitation and Soil Moisture in CFSv2 Near Gulf Coast Tropical Cyclone Landfall Locations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Landfalling tropical cyclones (TCs) produce intense winds, heavy precipitation, and damaging storm surges along the Gulf and East coast of the U.S. There is growing evidence that high antecedent soil moisture (SM) conditions preceding landfall can maintain or even intensify TCs over land, sustaining strong winds and precipitation further ...
