Minimum values within the polar vortex be 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 September had reached an area of around 25 meg comforting kilometres, larger than the average for the last decennary and anticipateed snug this size into early October. It had shrunk to around 20 one thousand thousand square kilometres by mid October and remained a similar size cashbox mid November, when it dropped rapidly and is now around 5 million square kilometres.

Its size from October to mid November was ascend to or above the record area for the time of year. The hole became much oval-shaped in mid October and the edge of the ozone hole passed over the circus tent of South America and the Falkland Islands, but then returned to a more(prenominal) circular form. The c ircum-polar ozone belt outside the vortex ha! s 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 previous(prenominal) its winter minimum, and warming is under way, though temperatures remain advantageously below the normal for this time of year. All of the Antarctic ozone stratum is now above the polar stratospheric cloud organic rectitude temperature. The edge of...If you want to get a full essay, club it on our website: BestEssayCheap.com
