Doc.ToBe Posted December 8, 2012 Share Posted December 8, 2012 My question is Whethher there is any particular reason that it is not present in equator or the arctic pole. Although I know it is not a hole but simply a depletion but why particularly in antatica only? It is also seen only during some months. Link to comment Share on other sites More sharing options...
Ophiolite Posted December 8, 2012 Share Posted December 8, 2012 As is often the case wikipedia come to the rescue. Reactions that take place on polar stratospheric clouds (PSCs) play an important role in enhancing ozone depletion.[8] PSCs form more readily in the extreme cold of Antarctic stratosphere. This is why ozone holes first formed, and are deeper, over Antarctica. The reactions referred to are the catalytic destruction of ozone by halocarbons (CFCs, halons and freons).
