The development of the Antarctic ozone hole in late winter and spring (September–November) is the most … noticeable phenomenon in the polar stratosphere. It has appeared every season since the early 1980s within the … stratospheric polar vortex…
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).
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.
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.
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.
To better attribute the total ozone column (TOC) anomalies observed from the ozone … measurements in Ukraine, the climatologies of annual ozone cycle along the latitudinal … band 40–60° N with the 30° step in longitude have been analysed.
The ozone hole over Antarctica is formed inside polar stratospheric vortex, which is under influence of large-scale planetary waves. The Quasi-stationary wave (QSW) in the spring Southern Hemisphere (SH)…
