The 2018-19 Arctic stratospheric polar vortex [PDF]
Weather, 2020 The stratospheric polar vortex is a westerly circulation that forms over the winter pole around 10-50 km above the surface, which is known to influence mid-latitude weather patterns. During 2018-19, the Arctic polar vortex demonstrated an unusually large amount of variability,\ud including a strong and persistent sudden stratospheric warming (SSW ...

Ozone and water vapour in the austral polar stratospheric vortex and sub-vortex [PDF]
Annales Geophysicae, 2004 Abstract. In-situ measurements of ozone and water vapour, in the Antarctic lower stratosphere, were made as part of the APE-GAIA mission in September and October 1999. The measurements show a distinct difference above and below the 415K isentrope. Above 415K, the chemically perturbed region of low ozone and water vapour is clearly evident.

Stratosphere‐troposphere evolution during polar vortex intensification [PDF]
Journal of Geophysical Research: Atmospheres, 2005 Stratosphere‐troposphere evolution associated with polar vortex intensification (VI) events is examined during the Northern Hemisphere winter. The incipient stage of a VI event is marked by anomalously low wave activity and descending westerly anomalies over the depth of the polar stratosphere.

Geophysical Research Letters, 2023 We use Aura Microwave Limb Sounder (MLS) trace gas measurements to investigate whether water vapor (H2O) injected into the stratosphere by the Hunga Tonga‐Hunga Ha'apai (HTHH) eruption affected the 2022 Antarctic stratospheric vortex.

Increased vertical resolution in the stratosphere reveals role of gravity waves after sudden stratospheric warmings [PDF]
Weather and Climate Dynamics, 2023 Sudden stratospheric warmings (SSWs) have a long-lasting effect within the stratosphere as well as impacts on the underlying troposphere. However, sub-seasonal forecasts of the winter polar stratosphere fail to use their full potential for predictability

Atmosphere, 2022 The stratospheric polar vortex is a large-scale cyclonic circulation that forms in a cold air mass in the polar region and extends from the middle troposphere to the stratosphere. The polar vortex is implicated in a variety of atmospheric processes, such

The Antarctic stratospheric nitrogen hole: Southern Hemisphere and Antarctic springtime total nitrogen dioxide and total ozone variability as observed by Sentinel-5p TROPOMI [PDF]
Atmospheric Chemistry and PhysicsDenitrification within the stratospheric vortex is a crucial process for Antarctic ozone hole formation, resulting in an analogous stratospheric “nitrogen hole”.

The joint effect of mid-latitude winds and the westerly quasi-biennial oscillation phase on the Antarctic stratospheric polar vortex and ozone [PDF]
Atmospheric Chemistry and PhysicsThe quasi-biennial oscillation (QBO) dynamically interacts with the extratropical atmosphere. However, the relationship between the QBO in austral winter and the Antarctic stratospheric polar vortex in spring remains unclear.

The impact of volcanic aerosol on the Northern Hemisphere stratospheric polar vortex: mechanisms and sensitivity to forcing structure [PDF]
Atmospheric Chemistry and Physics, 2014 Observations and simple theoretical arguments suggest that the Northern Hemisphere (NH) stratospheric polar vortex is stronger in winters following major volcanic eruptions.
