Polar Vortex Ozone Depletion. Scientists have discovered new evidence linking chlorine to the annual depletion of atmospheric ozone over the antarctic, it was reported today in the british science journal nature. This has major implications for stratospheric ozone depletion:
These clouds can only form at temperatures below about −80 °c (−112 °f). Direct emission of the no x free. Chlorine concentrations build up during the polar winter, and the consequent ozone destruction is greatest when the sunlight returns in spring.
