Zonal Asymmetry in Ozone Variations Over Antarctic Stations During the Life Cycle of Sudden Stratospheric Warmings Journal of Geophysical Research: Atmospheres, 2025 (Ref: 17412)
Category 1: Peer-reviewed literature

The zonal asymmetry in the Antarctic total ozone column (TOC) has been widely studied in … recent decades. However, little is known about how spatially dependent the TOC response is to sudden … stratospheric warmings (SSWs).

Antarctic tropopause by ozonesonde profiles from the Polar Atmospheric Chemistry at the Tropopause PACT database EGU General Assembly 2024, Vienna, Austria, 14–19 Apr 2024, 2024 (Ref: 17163)
Category 3: Abstract

Stratosphere–troposphere exchange can be considered globally within the framework of the atmosphere's general circulation as the transfer of air masses through the tropopause with ascending (descending) flows in the tropics (extratropical latitudes).

Antarctic total ozone longitude–latitude dependence on sudden stratospheric warmings EGU General Assembly 2024, Vienna, Austria, 14–19 Apr 2024, 2024 (Ref: 17160)
Category 3: Abstract

We use Multi-Sensor Reanalysis and ground-based total ozone content (TOC) data to study total ozone variations in Antarctica near the dates of sudden stratospheric warmings (SSW). Three events were analyzed, including the warmings in 1988, 2002 (major warming), and 2019.

Comparison of the planetary wave spectrum in the 2019 Antarctic SSW with the 2020 non-SSW strong vortex conditions using ozone data 10th SCAR Open Science Conference: Antarctica in a Changing World, 1-10 August 2022, Oral presentation, 2022 (Ref: 17025)
Category 3: Verbal presentation

The zonal wavenumber spectrum of planetary waves in the atmosphere above Antarctica was studied in two contrasting years: in 2019 when there was a sudden stratospheric warming (SSW), and in 2020 when the Antarctic stratospheric vortex was unusually strong and long-lived.

Rossby waves in total ozone distribution over the Arctic at the beginning of the 21st century 10th SCAR Open Science Conference: Antarctica in a Changing World, 1-10 August 2022, E-Poster presentation, 2022 (Ref: 17026)
Category 3: Poster

We have considered TOMS (2000–2004) and OMI (2005–2021) total ozone column (TOC) data sets for the second part of winter cold period (January–March). Variations in both total ozone and characteristics of the Fourier wave harmonics with zonal numbers 1–5 are analyzed.
