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.

Signature of the stratosphere–troposphere coupling on recent record-breaking Antarctic sea-ice anomalies [PDF]
The Cryosphere, 2023 In February 2023, the sea-ice extent around Antarctica dropped to 1.79×106 km2, setting a satellite-era record low for the second straight year. Recent records stress the need for further research into the factors behind record-breaking Antarctic sea-ice

Analyzing ozone variations and uncertainties at high latitudes during sudden stratospheric warming events using MERRA-2 [PDF]
Atmospheric Chemistry and Physics, 2022 Stratospheric circulation is a critical part of the Arctic ozone cycle. Sudden stratospheric warming events (SSWs) manifest the strongest alteration of stratospheric dynamics.

Observations of middle atmospheric H2O and O3 during the 2010 major sudden stratospheric warming by a network of microwave radiometers [PDF]
Atmospheric Chemistry and Physics, 2012 In this study, we present middle atmospheric water vapor (H2O) and ozone (O3) measurements obtained by ground-based microwave radiometers at three European locations in Bern (47° N), Onsala (57° N) and Sodankylä (67° N) during Northern winter 2009/2010 ...

Modulation of Atmospheric Rivers by the Arctic Stratospheric Polar Vortex
Geophysical Research Letters, 2022 Variability in atmospheric river (AR) frequency can drive hydrometeorological extremes with broad societal impacts. Mitigating the impacts of increased or decreased AR frequency requires forewarning weeks to months ahead.

The major stratospheric final warming in 2016: dispersal of vortex air and termination of Arctic chemical ozone loss [PDF]
Atmospheric Chemistry and Physics, 2016 The 2015/16 Northern Hemisphere winter stratosphere appeared to have the greatest potential yet seen for record Arctic ozone loss. Temperatures in the Arctic lower stratosphere were at record lows from December 2015 through early February 2016, with ...

Correlations of mesospheric winds with subtle motion of the Arctic polar vortex [PDF]
Atmospheric Chemistry and Physics, 2010 This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings.

Update of the Polar SWIFT model for polar stratospheric ozone loss (Polar SWIFT version 2) [PDF]
Geoscientific Model Development, 2017 The Polar SWIFT model is a fast scheme for calculating the chemistry of stratospheric ozone depletion in polar winter. It is intended for use in global climate models (GCMs) and Earth system models (ESMs) to enable the simulation of mutual ...
