- In this study, the possible influence of the Antarctic oscillation (AAO) on winter haze pollution
(indicated by atmospheric visibility after rain, fog, dust, snowstorms, etc. are removed) in North China (NC)
was investigated. The results show that the mean winter visibility (DecemberJanuaryFebruary visibility)
throughout most of eastern China is negatively correlated with the preceding AAO (AugustSeptember
October (ASO)AAO), especially in NC. The interannual correlation coefficient between DJFVIS in NC and
the ASOAAO is ？0.52, which is significant at the 99% level. The negative correlation suggests that an
enhancing (weakening) ASOAAO could be conducive to increases (decreases) of haze pollution in NC in
boreal winter. The responses of local and regional meteorological conditions to the ASOAAO support the
relationship between the ASOAAO and winter air pollution in NC. A preliminary mechanism analysis
shows that a positive ASOAAO may induce a sea surface temperature warming tendency in the
Northwestern Southern Indian Ocean. This warming then causes a wave trainlike pattern in the upper
troposphere along the jet stream and an anomalous zonal cell that weakens the regional Hadley circulation
from the Maritime continents to East Asia. All of these factors are favorable to the formation of anomalous
southerly and haze pollution in NC.
