[Analysis of aerosol concentration characteristics under continuous synoptic systems in Qingdao].

Based on weather data and data obtained by Particle Sizer GRIMM180 set up in Qingdao, aerosol was qualitively classified into sea-fog aerosol, refreshing aerosol and suspended dust aerosol. Analysis of mass concentration and number concentration of three different kinds of aerosols was conducted, and the results are shown as below: 1) total mass concentration of different kinds of aerosol is obviously different; 2) sea-fog aerosol primarily includes particles of which size ranging from 1 microm to 2.5 microm, and refreshing aerosol, includes particles of which size less than 1 microm, and suspended dust aerosol, includes particles of which size ranging from 2.
