The seasonal depletion of ozone in a large area of Antarctica.

CONT

Antarctic ozone hole ... The extremely cold temperatures within the polar vortex lead to formation of polar stratospheric clouds (PSCs) over large areas in early winter. These clouds are the key to the severe ozone depletion which has become known as the ozone "hole". PSCs form at the lower, colder altitudes (10-25 kilometres). The clouds are a major factor in causing large total column ozone depletion in the springtime Antarctic stratosphere.
