中文摘要：

利用1981—2011年TOMS卫星逐月TCO资料、NASA极涡面积监测逐日资料及1979—2012年ERA-Interim再分析逐日资料,通过异常增加个例分析研究了北极极涡对极地平流层臭氧含量的影响。结果表明：1984年和1989年2月北极极涡分别表现为偏移型和分裂型,由于中高纬向极地输运的行星波的增强导致极地平流层极涡减弱,使得这2年3月初极涡提前崩溃,进而引起极区温度升高,原本在2月形成的极地平流层云（PSCs）消失,臭氧化学损耗减弱。由于高浓度臭氧从中纬输送到极区,导致这2年3月北极区臭氧柱总量（TCO）异常偏高。值得注意的是,尽管1984年和1989年整个冬季极涡面积都相对较大,但由于3月初极涡的提前崩溃使得这2年臭氧迅速恢复,且极涡的持续时间比极涡面积对臭氧的影响更大。

英文摘要：

Based on total column ozone（TCO） from TOMS satellite,polar vortex area from NASA during 1981-2011 and ERA-Interim reanalysis data during 1979-2012,the abnormal increasing year of total column ozone from February to March in stratosphere of the Arctic was selected. And the influences of polar vortex on ozone content in stratosphere of the Arctic in abnormal years were analyzed. The results show that TCO presented significantly positive anomalies from February to March of 1984 and 1989 in stratosphere of the Northern Hemisphere. The Arctic polar vortex in February of 1984 and 1989 appeared deviation and splitting,respectively. The polar vortex in stratosphere of the Northern Hemisphere weakened due to the strengthened planetary wave coming from the middle and high latitudes in February,which caused the collapse of polar vortex in advance in early March of 1984 and 1989 and the disappearing of polar stratospheric cloud forming in February,that further led to the weakening of ozone chemical depleting and the increase of air temperature in March.TCO in the Arctic was abnormally high in March of 1984 and 1989 because the ozone transported from the middle latitude to the polar. In addition,the influence of the duration of the polar vortex on Arctic ozone was greater than that of the area of the polar vortex.
