The Ozone Hole 2022

Antarctic Situation at 2022 October 14 British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  Ozone values currently range from a low of around 110 DU within the polar vortex to around 400 DU just outside it.  The ozone hole was at its largest with an area of around 25 msqkm in early October, larger than average for the time of year, but similar to that of 2021 and 2020.  The 2022 polar vortex has passed its largest, with a size of 36 million square kilometres (msqkm) in late September, which is much larger than average for the time of year.  It now covers around 33 msqkm, still much larger than average for the time of year.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature of the ozone layer over Antarctica has passed the annual minimum but is still below the -78°C Polar Stratospheric Cloud (PSC) formation threshold over much of Antarctica.  The area with potential PSC reached a peak of 28 msqkm in mid August, larger than the long term average.  It has now shrunk to 8 msqkm, a little above average in size.  There is some long period wave activity, and the lower stratosphere was much less stable in the last week of August.  Stability has returned to about average.  Ozone depletion is still expected to continue over the coming weeks, with the ozone hole becoming more elliptical towards the end of the first week of October.

In early October the 2022 Ozone Hole grew in size to become one of the largest ever.

Antarctic Situation at 2022 September 30 British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  The 2022 polar vortex is near its largest, with a current size of 35 million square kilometres (msqkm), which is much larger than average for the time of year.  Ozone amounts have risen outside the polar vortex and are declining within it.  Ozone values currently range from a low of around 120 DU within the vortex to nearly 400 DU just outside it.  The ozone hole is near its largest and has an area of around 23 msqkm, larger than average for the time of year, but similar to that of 2021 and 2020.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature of the ozone layer over Antarctica has passed the annual minimum but is still below the -78°C Polar Stratospheric Cloud (PSC) formation threshold over much of Antarctica.  The area with potential PSC reached a peak of 28 msqkm in mid August, larger than the long term average.  It has now shrunk to 17 msqkm, but remains above average in size.  There is some long period wave activity, and the lower stratosphere was much less stable in the last week of August.  Stability has returned to about average.  Ozone depletion is still expected to continue over the coming weeks, with the ozone hole becoming more elliptical towards the end of the first week of October.

 

Antarctic Situation at 2022 September 16 British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  The 2022 polar vortex is near its largest, with a current size of 35 million square kilometres (msqkm), which is much larger than average for the time of year.  Ozone amounts have risen outside the polar vortex and are declining within it.  Ozone values currently range from around 150 DU to 380 DU.  The growing ozone hole has an area of around 21 msqkm, larger than average for the time of year, but similar to that of 2021.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature throughout the ozone layer over Antarctica is near the annual minimum and is below the -78°C Polar Stratospheric Cloud (PSC) formation threshold over much of Antarctica.  The area with potential PSC reached a peak of 28 msqkm in mid August, larger than the long term average.  It has now shrunk to 20 msqkm, but remains above average in size.  There is some long period wave activity, and the lower stratosphere was much less stable in the last week of August.  Stability has returned to about average.  Ozone depletion is still expected to intensify over the coming weeks.

 

Antarctic Situation at 2022 August 26 British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  The 2022 polar vortex has formed, with a current size of 34 million square kilometres (msqkm), which is near its largest ever     for the time of year.  Ozone amounts have risen outside the polar vortex and are declining within it.  Ozone values currently range from around 180 DU to 370 DU.  The growing ozone hole has an area of around 9 msqkm, about average for the time of year.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature throughout the ozone layer over Antarctica is near the annual minimum and is below the -78°C Polar Stratospheric Cloud (PSC) formation threshold over much of Antarctica.  The area with potential PSC reached a peak of 28 msqkm in mid August, larger than the long term average.  It has now shrunk a little to 24 msqkm, but remains above average in size.  There is some long period wave activity, and the lower stratosphere has become much less stable over the last week.  Ozone depletion is still expected to intensify over the coming weeks.

 

Antarctic Situation at 2022 August 19 British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  The 2022 polar vortex has formed, with a current size of 34 million square kilometres (msqkm), which is the largest ever for the time of year.  Ozone amounts have risen outside the polar vortex and are declining within it.  Ozone values currently range from around 220 DU to 380 DU.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature throughout the ozone layer over Antarctica is nearing the annual minimum and is now below the -78°C Polar Stratospheric Cloud (PSC) formation threshold in the centre of the vortex, with a potential PSC area of 28 msqkm, a little larger than the long term average.  There is some long period wave activity, but the lower stratosphere remains relatively stable.

Antarctic Situation at 2022 July 29  British Antarctic Survey Ozone Bulletin

Antarctic ozone today:  The 2022 polar vortex has formed, with a current size of 30 million square kilometres (msqkm), which is larger than average for the time of year.  Ozone amounts have risen outside the polar vortex and are declining within it.  Ozone values currently range from around 240 DU to 390 DU.  The ozone layer temperature is highest around Antarctica and declines towards the equator and pole. The temperature throughout the ozone layer over Antarctica is declining and is now below the -78°C Polar Stratospheric Cloud (PSC) formation threshold in the centre of the vortex, with a potential PSC area of 27 msqkm, a little larger than the long term average.  There is some long period wave activity, but the lower stratosphere remains relatively stable.
