These data sets included the daily Received in revised form 12 August 2014 wind speed, wind direction, visibility, and precipitation from 1956 to 2010, hourly PM10 concentration Accepted 13 August 2014 from 2008 to 2010, and the NCEP/NCAR reanalysis data of global atmospheric circulation from 1956 to 2010. The trend of aerosol concentration and its correlations with wind speed and wind direction in Keywords: winter were analyzed. Results indicated that there was an increase in the number of haze days in winter Aerosol
