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.

北极地区臭氧层数量的年际变化不仅取决于化学破坏的变化，也取决于臭氧输送的变化。分析了与臭氧化学破坏和臭氧输送有关的臭氧浓度、N2O浓度、大气环流和臭氧破坏率的变化。结果表明，以平流层下部N2O浓度和波动通量为代表的动力学指数进行年际划分时，北极地区臭氧浓度与卤素含量具有较高的相关性。
