Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

High Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Stratospheric Polar Vortex Exerts Different Controls on the Transport of Tropical and Mid‐Latitude Volcanic Aerosols

Geophysical Research Letters
Moderate volcanic eruptions and extreme wildfires in recent two decades have persistently perturbed global stratospheric aerosol loadings. Based on satellite observations and climate model simulations, we find that these events contribute to ∼67% of ...

Stratospheric influence on the winter North Atlantic storm track in subseasonal reforecasts [PDF]

Weather and Climate Dynamics
Extreme stratospheric polar vortex events, such as sudden stratospheric warmings (SSWs) or extremely strong polar vortex events, can have a significant impact on surface weather in winter.

CNR Ozone Sounding Merged (COSM) Dataset From Existing Global Archives

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
The COSM dataset unifies over 101,000 ozonesonde profiles from SHADOZ, NDACC and WOUDC into a harmonized, quality‐controlled archive spanning 1978–2024. It improves global spatial and temporal coverage, supports climate and chemistry studies, and provides a robust resource for satellite validation, model evaluation and trend analysis.

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies (Ep ${E}_{p}$) in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipation at all altitudes from 30 to 110 km.

Stratosphere–Troposphere Coupling During Cold Air Outbreaks in the Eastern United States

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Cold air outbreaks (CAOs) are extreme weather events characterized by the equatorward displacement of polar air. This study investigates CAOs occurring along the East Coast of the US and establishes that approximately 16% are driven by stratosphere‐troposphere coupling through wave dynamics.

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Regional and Seasonal Variability in Decreasing Contrail Cirrus Cloudiness Using Sustainable Aviation Fuel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The impact of aviation induced contrail cirrus on Earth's radiation budget depends on the optical depth (OD) and the life time of these clouds. Their tendency to enhance global warming may be mitigated by replacing conventional kerosene with fuels that form fewer soot particles, such as sustainable aviation fuels (SAF). The resulting reduction
