At the location of the south polar vortex for the normal year, the mixing ratios of O3 and CH4 increased, HCl and NO decreased, but NO2 and H2O did not accord with a given rule at all altitudes over Antarctica in 2002, which was related to the change of the vortex and the dynamical transportation after the SSW, and affected by the reduced polar stratospheric clouds and weakened processes of heterogeneous chemistry.

通过比较还发现，在通常年份极涡所处的位置上，2002年O3和CH4的混合比有所增加，HCl和NO的混合比有所减少，而NO2和H2O在不同高度上的变化特点不同。这与爆发性增温之后极涡和动力输送的变化有关，同时由于增温导致极地平流层云中相关冰相反应的减弱也是一个重要的原因。
