Minimum values within the polar vortex atomic number 18 around 200 DU. The 2011 hole is predicted to be over by middle December. The hole began to form in mid August, and by mid Septemb er had reached an area of around 25 one one thousand million million lusty kilometres, larger than the average for the last decennary and anticipateed unaired this size into early October. It had shrunk to around 20 million square kilometres by mid October and remained a similar size till mid November, when it dropped rapidly and is now around 5 million square kilometres.

Its size from October to mid November was come along to or above the record area for the time of year. The hole became much egg-shaped in mid October and the edge of the ozone hole passed over the summit meeting of South America and the F alkland Islands, but then returned to a muc! h circular form. The circum-polar ozone belt outside the vortex has roughly areas near 350 DU, particularly between the continent and Australia, but utmost levels are subsiding from peaks above 400 DU. The lower stratospheric temperature is thoroughly by its winter minimum, and warming is under way, though temperatures remain easily below the normal for this time of year. All of the Antarctic ozone seam is now above the polar stratospheric cloud organic rightfulness temperature.
