The build up of CFCs and other chlorine and bromine containing species in the atmosphere has lead to significant stratospheric ozone depletion, especially over Antarctic during spring. This ozone depletion leads not only to changes in UV radiation reaching the surface, but also changes in changes in tropospheric weather systems and climate, and ocean circulations. Using observations and a hierarchy of numerical models we are examining the impact of the ozone hole on southern hemisphere weather and climate.
