Abstract

The purpose of this study was to describe the meteorological features and PM10 concentration of the dust event observed in South Korea from 31 March to 2 April 2007. This typical dust event for Korea exhibited baroclinic instability at the 850 hPa level over Mongolia. The conditions propelled a large amount of dust into the air, where it was subsequently transported to the Korean peninsula. The Asian dust event studied was the sixth of the 13 events that occurred in Korea in 2007; its maximum PM10 concentration of 2,019 μg m3 (hourly average) was recorded inDaegu in Korea. Naked-eye observation of the event started in

Baengnyeongdo on 07UTC 31 March and ended in Jejudo on 01UTC 2 April 2007. The duration of this event in Korea was 46 hours and 15 minutes Japan. Photographs were taken in Seoul on 1 and 2 April 2007 show that the dust resulted in poor visibility. Mt. Gwanak and the 63 buildings in Yeouido are completely obscured by the dust in, one pair of photographs taken when the PM10 concentration was 1,349 μg m3 (5-minute average) from the Korea Meteorological Administration (KMA) headquarters in Shindaebang-dong, Seoul. However, the buildings and mountain can be discerned faintly in another pair of photographs, taken when the PM10 concentration was 37 μg m3.
