Both dynamical and chemical mechanisms have been advanced to explain the decrease in total ozone in the Antarctic spring. Further analysis of satellite measurements show that during any one year the September decline in total ozone near the South Pole is compensated by an increase at mid-latitudes. The total ozone amount from 44¿ S to the pole remains almost unchanged from August through November even though both the polar and mid-latitude values reach extremes during this period. These observations suggest that the variations within the spring season in south polar total ozone are governed by dynamical redistribution rather than chemical processes.
