Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract The hydroxyl radical (OH) determines the atmospheric lifetime of many pollutants like methane (CH4 ${\text{CH}}_{4}$). This study isolates climate change, air pollution control and CH4 ${\text{CH}}_{4}$ mitigation effects on OH concentrations ([OH]) and CH4 ${\text{CH}}_{4}$ lifetime, by analyzing Coupled Model Intercomparison Project Phase 6 (

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract The newly developed emission‐driven capability of CESM2 allows methane concentrations to be more realistically simulated based on emissions, transport, and atmospheric chemistry, rather than being prescribed as lower boundary conditions as in most previous global Earth system modeling studies.

Intraseasonal Linkages of Winter Surface Air Temperature Between Eurasia and North America
Geophysical Research LettersWintertime temperature extremes sometimes show a continental linkage between Eurasia and North America (NA), but whether these connections are coincidental or dynamically robust remains unclear.

Annular variability and eddy-zonal flow interactions in a simplified atmospheric GCM. Part 1: Characterization of high and low frequency behaviour [PDF]
, 2008 Experiments have been performed using a simplified, Newtonian forced, global circulation model to investigate how variability of the tropospheric jet can be characterized by examining the combined fluctuations of the two leading modes of annular ...

, 2023 Extreme events of the stratospheric polar vortex can modulate subsequent surface weather at subseaonal to seasonal (S2S) timescales. Moreover, they are considered to form windows of opportunity for tropospheric forecasting. This study aims to improve understanding of how the canonical surface response of polar vortex events translates into modulated ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract The Atlantic Meridional Overturning Circulation (AMOC) is a key regulator of the Earth's climate. Here using water hosing experiments with a coupled climate model, we show that a weakened AMOC leads to a significant boreal winter upper troposphere/lower stratosphere (UTLS) warming over the extratropical North Pacific (ENP).

Weather and Climate ExtremesWeak stratospheric polar vortex (WSPV) events are dynamically connected with the variations in the tropospheric circulation, serving as crucial harbingers for surface cold extremes in the Northern Hemisphere.

When Thunderstorms Reach the Stratosphere: Why Storm Structure May Matter for Climate
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract Deep convection that overshoots the tropopause provides one of the fastest pathways for exchanging air between the troposphere and the stratosphere. Using extensive in situ observations from the dynamics and chemistry of the summer stratosphere (DCOTSS) campaign, Shepherd et al.

On the surface impact of Arctic stratospheric ozone extremes
Environmental Research Letters, 2015 A comprehensive stratosphere-resolving atmospheric model, with interactive stratospheric ozone chemistry, coupled to ocean, sea ice and land components is used to explore the tropospheric and surface impacts of large springtime ozone anomalies in the ...

International Journal of Climatology, Volume 46, Issue 6, May 2026.This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.
