| Description: |
The 2015 Antarctic ozone hole area was larger and formed later than recent years, according to scientists. On October 2, 2015, the ozone hole expanded to 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North America. In general, the colder the preceding winter, the greater the ozone depletion and the larger the ozone hole area. This past winter, the stratosphere was colder than average, and the atmospheric circulation over Antarctica was very stable, leading the ozone hole to become the fourth-largest on record.
