Short summary

We developed a new indicator, Siberian High position index (SHPI), which depicts the mean longitudinal position of the SH, as a new indicator of the large-scale circulation pattern that controls wintertime air quality in China. This SHPI explains 58% and 64% of the interannual variability of winter AOD during 2001-2013 over North China and South China, respectively. The extreme PM pollution of January 2013 is found to be associated with extremely high values of SHPI.
