The purpose of this study is to take-out of prediction factor as weather conditions on the long-term retardation status of Asian dust in Korea. Recently, the frequencies and retardation days of Asian dust originated from deserts in China and Mongolia have increased a lot in Korea, especially the days of retardation in Seoul have reached to 27 days in 2001 and 9 days per one time in 1998.
Of course, the main causes of Asian dust depend on the climate of source area, but it was estimated that the weather factors of Korea are related with the long-term retardation in some degree. After analyzing the relation with weather conditions, following brief summaries was observed as conclusions. Weather and humidities are responded to the long-term retardation of Asian dust in Korea. Continuous haze and smog, also arid climate are contributed to make longer the retardation of Asian dust. But rainy and snowy climate are indicated the end of retardation status.
Additionally this study concerning on the long-term retardation goes on to find another factors as atmospheric pressure and temperature etc.
