Year-to-year variation in ozone amount in the Arctic area depends on not only the variation in the chemical destruction but also in ozone transport. The variations in ozone concentration, N2O concentration, the general circulation, and ozone destruction rate are analyzed, which are associated with chemical ozone destruction and ozone transport. The results show that a high correlation between ozone concentration and halogen amount is obtained in the Arctic region when the years are classified by the dynamical indices that are represented by the N2O concentration and the wave flux in the lower stratosphere.
