Why was the ozone destroyed in the Antarctic first?

The Antarctic has conditions that are not found anywhere else to the same degree and are good for destroying ozone. During the Antarctic winter and spring a belt of winds blows around the continent and keeps the air in one place and prevents air from warmer climates from mixing in. Because Antarctica is land, the extremely cold temperatures needed to form the special kinds of clouds that help to destroy the ozone are found there. These two factors are believed to be the main reason why ozone depletion is worst in Antarctica.
