The purpose of this study is to find out the air flow patterns affecting the PM10 concentration in Busan and the potential
sources within each trajectory pattern. The synoptic air flow trajectories are classified into four clusters by HYSPLIT model
and the potential sources of PM10 are estimated by PSCF model for each cluster from 2008 to 2012. The potential source
locations of PM10 are compared with the distribution of PM10 anthropogenic emissions in east Asia developed in 2006 for the NASA INTEX-B mission. The annual mean concentrations of PM10 in Busan decreased from 51 ug/m3
in 2008 to 43 ug/m3 in 2012. The monthly mean concentrations of PM10 were high during a spring season, March to May and low during a summer season, August and September. The cluster2 composed of the air trajectories from the eastern China to Busan through the west sea showed the highest frequency, 44 %. The cluster1 composed of the air trajectories from the inner Mongolia region to Busan through the northeast area of China showed the second high frequency, 26 %. The cluster3 and 4 were composed of the trajectories originated in the southeast sea and the east sea of Busan respectively and showed low frequencies. The concentrations of in each cluster were 47 ug/m3 in cluster1, 56 ug/m3
in cluster2, 42 ug/m3 in cluster3 and 37 ug/m3 in cluster4.
From these results, it was proved that the cluster1 and 2 composed of the trajectories originated in the east and northeast area of China were the causes of high PM10 concentrations in Busan. The results of PSCF and CWT model showed that the potential sources of the high PM10 concentrations were the areas of the around Mongolia and the eastern China having high emissions of PM10 from Beijing, Hebei to Shanghai through Shandong, Jiangsu.
