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.
