The source region of “Asian Dust”
Asian Dust known as Hwangsa that affects the Korean peninsula occurs most frequently in the spring season, and originates in the arid and semi-arid regions of sand deserts in Mongolia and northern China., including Badainjaran, Tengger, Mu Us, Hunsandakue, and Keoeolchin, Gobi region and Loess regions of the Asian continent. The southeastward moving low-pressure system accompanied with the cold fronts disseminates sand and dust into the atmospheres, often resulting in the low visibility of less than one km in the downwind region such as NE China and Korea.
