It had shrunk to around 20 million square kilometres by mid October and remained a similar size coin bank mid November, when it dropped rapidly and is now around 5 million square kilometres. Its size from October to mid November was uprise to or to a higher place the record area for the time of year. The hole became much oval in mid October and the edge of the ozone hole passed over the poll of South America and the Falkland Islands, but then returned to a more(prenominal) 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 former(prenominal) its winter minimum, and warming is under way, though temperatures remain considerably bel ow the normal for this time of year.
