Antarctic Situation at 2013
September 20
British Antarctic Survey Ozone Bulletin
The ozone layer is at its winter temperature, and was
significantly cooler than the long term mean until late August. It is beginning
to warm, but Polar Stratospheric Clouds (PSCs) are still forming within the
polar vortex. On a few days in early August and again in mid September new
record minima were set. The 2013 winter polar vortex is near its largest and has
generally been a little larger than the average over the last decade. It remains
quite stable. According to NOAA SBUV measurements the ozone hole began to form
in mid August and is now around 19 million square kilometres in extent [The
continent covers 14 million sq. km.]. This is larger than in 2012, but smaller
than the average over the last decade. The area with temperatures colder than
-78°C is around average. Highest ozone values surround Antarctica at about 45 –
60°S in a horse-shoe between South America, Africa and Australia, with highest
values above 430 DU south of the Indian Ocean. Lowest values, below 150 DU, are
broadly over the base of the Antarctic Peninsula. The 2013 ozone hole is nearing
its maximum depth and size. On occasion atmospheric vertical motions create
small areas with ozone substantially below the long term average.

significantly cooler than the long term mean until late August. It is beginning
to warm, but Polar Stratospheric Clouds (PSCs) are still forming. On a few days
in early August and again in mid September new record minima were set. The 2013
winter polar vortex is near its largest and was a little larger than the average
over the last decade until the end of July. It is now around average in size and
remains quite stable, though the top of the ozone layer is beginning to warm.
According to NOAA SBUV measurements the ozone hole began to form in mid August
and is now around 19 million square kilometres in extent [The continent is 14
million sq. km.]. This is larger than in 2012, but smaller than the average over
the last decade. The area with temperatures colder than -78°C is around average.
Highest ozone values surround Antarctica at about 45 – 60°S, with peak values
above 400 DU in a horse-shoe between South America, Africa and Australia. Lowest
values, below 150 DU, are over Coates Land. The 2013 ozone hole is nearing its
maximum depth and size. On occasion atmospheric vertical motions create small
areas with ozone substantially below the long term average. Different satellites
give different views of the exact ozone distribution.

winter polar vortex is growing and was a little larger than the average over the

distribution is becoming organised, with highest values up to around 400 DU

The ozone layer is cooling with the 2013 winter polar
vortex forming, and it is cold enough for PSC formation. Ozone distribution is
beginning to organise, with highest values at around 360 DU surrounding
Antarctica at about 50 – 60°S and lowest values at around 260 DU over the
continental margins. The 2013 ozone hole is beginning to be created.

Antarctic Survey Ozone Bulletin
The 2012 ozone hole is long over and the 2012 winter polar
vortex over Antarctica has dissipated. Ozone distribution is rather patchy with
lowest values at around 240 DU over the Weddell Sea and highest values at around
350 DU surrounding Antarctica. The ozone layer is now cooling with the 2013
winter polar vortex forming, and it is cold enough for PSC formation, so the
2013 ozone hole is beginning to be created.
