Why does Ozone depletion occur in Polar vortex cause melting ?1)Ozone absorbs large amounts of ultraviolet radiation in the stratosphere 2) Ozone depletion over Antarctica can cause a cooling of around 6 °C in the local stratosphere 3) This cooling intensifies westerly winds which flow around the continent (the polar vortex) 4) This intensifed westerly winds prevents outflow of the cold air near the South Pole 5) Hence continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent.
What is a polar vortex ? an upper level low-pressure area lying near the Earth's pole. There are two polar vortices in the Earth's atmosphere, which overlie the North, and South Poles
Where does Ozone depletion occur in the polar region ?within the polar vortices – particularly over the Southern Hemisphere – reaching a maximum depletion in the spring
