Cold-season atmospheric conditions associated with sudden changes in PM10 concentration over Seoul, Korea

Abstract Previous studies have intensively studied the atmospheric conditions associated with high- and low-PM10 (particulate matter  80 μg m−3) to the moderate concentrations, there was no distinct pattern except for a high-pressure anomaly in the upper atmosphere. These results improve our understanding of the mechanisms behind the sudden changes in PM10 due to atmospheric conditions over East Asia.
