Where is the Antarctic ozone hole most often observed?
Quick Answer
The Antarctic ozone hole is most often observed over Antarctica, especially above the South Pole region in spring. It forms in the lower stratosphere.
The Full Story
The Antarctic ozone hole is a seasonal thinning of ozone in the stratosphere above Antarctica. It is usually most pronounced during the Southern Hemisphere spring, from about September to October. The phenomenon is linked to human-made chlorofluorocarbons, or CFCs, which release chlorine and bromine compounds that destroy ozone in cold polar conditions. International action under the Montreal Protocol has helped the ozone layer begin a slow recovery.
