Minimum determine within the polar whirlpool are around cc DU. The 2011 hole is predicted to be everyplace by middle(prenominal)dledle December. The hole began to form in mid August, and by mid family had reached an country of around 25 zillion square kilometres, big than the average for the last ten and anticipateed near this size into aboriginal October. It had shrunk to around 20 million square kilometres by mid October and sticked a similar size till mid November, when it dropped quickly and is now around 5 million square kilometres.

Its size from October to mid November was near to or in a higher place the record area for the time of year. The hole became a lot elliptical in mid October and the edge of the ozone hole passed everyplace the tip of South the States and the Falkland Islands, but then returned to a more circular form. The circum-polar ozone fringe outside the vortex has nigh areas near 350 DU, particularly between the continent and Australia, but period levels are subsiding from peaks above 400 DU. The lower stratospheric temperature is exhaustively past its winter minimum, and change is under way, though temperatures remain substantially below the mean(prenominal) for this time of year. All of the Antarctic ozone layer is now above the polar stratospheric cloud primitive law temperature.
