In this study, future status changes of Asian dust were investigated by the analysis of the change of generation conditions as the trends of desert areas changing(saltation progress) and monitoring the transformation of wind direction. It was found that the source areas of Asian dust were slightly reduced, and move to eastern area from western of China during recent 10 years. Because of these reasons, Asian dusts affect to neighborhood nations as Korea and Japan more severely than past. So sometimes it was happened to high concentration episodes, that maximum PM10 concentrations in atmosphere are 2,000~3,000㎍/m3.It didn't occurred that any remarkable transition of status on Asian dust due to the climate change till now except the slightly transition for winter at Gosan, Jeju. The transition of wind direction as westerly wind mainly occurs by the temperature change of ocean, but this result come into existence for several decades. So the transition of wind direction due to the global warming will be observe continuously in future during several decades.
