“…The dominant role of physical dynamics for Corresponding author: WANG Jun, wangjun@mail.iap.ac.cn extratropical ozone is also emphasized in the modeling studies of Kinnersley and Tung (1998). Many studies have investigated variations in ozone and temperature on various time scales, including trends (Staehelin et al, 2001;Austin et al, 2008), as well as variations associated with other meteorological factors (Ziemke et al, 1997;Steinbrecht et al, 2001;Zhou et al, 2003;Zou et al, 2005).…”

“…In the 1990s, only a few satellite-based measurements, such as the Polar Ozone and Aerosol Measurement experiment (POAM II) (Randall et al, 1995) and instruments onboard the Upper Atmosphere Research Satellite (UARS) (e.g., Froidevaux et al, 1994), could observe the high northern latitudes. That is why most of early studies on wintertime ozone in the northern hemisphere were confined southward of 60 • N (e.g., Zou et al, 2005).…”

The ozone budget inside the middle stratospheric polar vortex (24-36 km) ) is used to analyze the observed variation in polar vortex ozone during the stratospheric sudden warming (SSW) events. Both MIPAS measurement and MOZART-3 calculation show that a pronounced increase (26-28 DU) in the polar vortex ozone due to the SSW events. Due to the weakening of the polar vortex, the exchange of ozone mass across the edge of the polar vortex increases substantially and amounts to about 3.0 × 10 7 kg according to MOZART-3 calculation. The enhanced downward transport offsets about 80% of polar vortex ozone mass increase by horizontal transport. A "passive ozone" experiment shows that only ∼55% of the vertical ozone mass flux in February and March can be attributed to the variation in vertical transport. It is also shown that the enhanced downward ozone above ∼32 km should be attributed to the springtime photochemical ozone production. Due to the increase of air temperature, the NOx reaction rate increases by 40%-80% during the SSW events. As a result, NOx catalytic cycle causes another 44% decrease in polar vortex ozone compared to the net ozone changes due to dynamical transport. It is also shown that the largest change in polar vortex ozone is due to horizontal advection by planetary waves in January 2003.

“…The positive phase of the AO is related to a strengthened polar vortex, lower than normal air pressure, and enhanced ozone depletion over high latitudes (Liu and Hu, 2021). According to Thompson and Wallace (1998) or Zou et al (2005) this correlation is more pronounced over Eurasia than over the North Atlantic region. Thompson and Wallace (2000, their Fig.…”

Abstract. In this study we present an updated perspective on near-global total ozone trends for the period 1995–2020. We use the GOME-type Total Ozone Essential Climate Variable (GTO-ECV) satellite data record which has been extended and generated as part of the European Space Agency’s Climate Change Initiative (ESA-CCI) and European Union Copernicus Climate Change Service (EU-C3S) ozone projects. The focus of our work is the analysis of regional patterns in the ozone trend as well as the investigation of its seasonal dependence. In the Southern Hemisphere we found regions that indicate statistically significant positive trends increasing from 0.6 ± 0.5 % decade−1 in the subtropics to 1.0 ± 0.9 % decade−1 in the middle latitudes and 2.8 ± 2.6 % decade−1 in the latitude band 60°–70° S. In the middle latitudes of the Northern Hemisphere the trend exhibits distinct regional patterns, i.e. latitudinal and longitudinal structures. Significant positive trends (∼1.5 ± 1.0 % decade−1) over the North Atlantic region as well as negative trends (−1.0 ± 1.0 % decade−1) over Eastern Europe were found. Moreover, these trends indicate a correlation with long-term changes in tropopause pressure. Total ozone trends in the tropics are not significant. Regarding the seasonal dependence of the trends we found only very small variations over the course of the year. However, we identified different behavior depending on latitude. In the latitude band 40°–70° N the positive trend maximizes in boreal winter from December to February. In the middle latitudes of the Southern Hemisphere (35°–50° S) the trend is maximum from March to May. Further south toward the high latitudes (55°–70° S) the trend denotes a relatively strong seasonal cycle which varies from 2 % decade−1 in December and January to 3.8 % decade−1 in June and July.
