The 2026 cold wave brought northern Fennoscandia its coldest 2‐week period since 1987

Weather, EarlyView.
During late December 2025 and January 2026, a severe and long‐lasting cold wave affected northern Fennoscandia. In this article, we aim to quantify the extremity of the 2026 cold wave and evaluate the atmospheric conditions that led to the persistent cold anomalies.

A new class of vacillations of the stratospheric polar vortex [PDF]

Quarterly Journal of the Royal Meteorological Society, 2016
A new class of persistent vacillations of the winter polar vortex, under the action of topographic wave forcing and radiative cooling, is identified in numerical integrations of the rotating shallow‐water equations. The vacillations are obtained provided only that care is taken to prevent the unconstrained growth of tropical easterlies that otherwise ...

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.

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.

Covalent Organic Frameworks in Smart Food Packaging: Advances, Challenges, and Future Prospects

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food preservation challenges have positioned packaging as a rapidly evolving, innovation‐driven field, with smart packaging offering transformative solutions. Among advanced materials, covalent organic frameworks (COFs) have attracted growing attention due to their permanent porosity, structural tunability, high surface area, and chemical ...

Biomass Burning in Australia: No Evidence for Carbonyl Sulfide (OCS) Enhancement in Fire Plumes From In‐Situ Measurements During SouthTRAC

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Determining the atmospheric abundance and the emission sources of carbonyl sulfide (OCS) plays a crucial role for the sulfur budget in the atmosphere. In addition to its main anthropogenic and biogenic sources, biomass burning is assumed to be an essential, but not well constrained source of OCS.

Stratospheric Aerosol From Above: Laser‐Ablation Mass Spectrometer Samples Polar Vortex Air for the First Time

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The JGR paper by Lawler et al. (2025, https://doi.org/10.1029/2025jd043530) marks a significant and historic first, the PALMS single‐particle chemical analysis sampling deep stratospheric Arctic vortex air for the first time. The analysis finds ∼90% of sulfate aerosol particles in the deepest stratosphere air (100–130 ppb N2O) are meteoric ...

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.
