Cyclone‐Like Features Within the Stratospheric Polar‐Night Vortex

Geophysical Research Letters
Distinctive synoptic‐scale (∼1,500 km) flow features are identified within the core of the stratospheric polar‐night vortex at stratopause altitudes (∼50 km).

A Study of the Low-Ozone Episode over Scandinavia and Northwestern Russia in March 2025

Atmosphere
Following a very cold first half of the Arctic stratosphere winter of 2024–2025, the stratospheric polar vortex weakened from late February. The increase in the polar lower stratosphere temperature led to a decrease in the polar stratospheric cloud (PSC)

The role of the basic state in the climate response to future Arctic sea ice loss

Environmental Research: Climate
There is great uncertainty in the atmospheric circulation response to future Arctic sea ice loss, with some models predicting a shift towards the negative phase of the North Atlantic Oscillation (NAO), while others predicting a more neutral NAO response.

A three-dimensional model comparison of PSC processing during the Arctic winters of 1991/1992 and 1992/1993

Annales Geophysicae
A three-dimensional transport model has been used to compare and contrast the extent of processing by polar stratospheric clouds during the northern hemisphere winters of 1991/1992 and 1992/1993.
