It is found that the model simulates quite reasonably the dust (PM10) concentrations both in the dust source region and the downstream region of Korea. The starting and ending times of most dust events and their peak concentration occurrence times are well simulated. The monthly mean maximum surface dust concentration (PM10) is found to be 267μgm−3 in the domain of central northern China (CNC). Monthly total maximum dust emission of more than 32t km−2 and that of deposition of more than 25.4t km−2 (dry deposition of 24t km−2 and wet deposition of 1.4t km−2) are found to occur in the domain CNC, whereas the monthly mean minimum surface dust concentration (PM10) is found to be 0.2μgm−3 in the domain of the Tibetan Plateau, where the monthly total dust emission (4kgkm−2) and the monthly total dust deposition (9kgkm−2) are found to be minimum. This monthly total dust deposition of 9kgkm−2 (dry deposition of 7kgkm−2 and wet deposition of 2kgkm−2) is as large as 2.25 times of that of emission (4kgkm−2), suggesting net dust influx toward the Tibetan Plateau from the surrounding dust source regions. It is also found that the ratio of the total dust deposition to the total dust emission in the source region increases toward the downstream direction from 0.4 in the upstream source region of Taklimakan to 0.80 in the downstream source region of northeastern China. More than 90% of the total dust deposition is found to be contributed by dry deposition due to the lack of precipitation in the dust source region. The monthly mean dust concentration (PM10) is found to decrease with distance away from the dust source region. The monthly mean dust concentration of 62μgm−3 over the Yellow Sea (YES) decreases to 4.3μgm−3 over the Northwestern Pacific Ocean (NWP). The monthly total dust deposition in the downstream region is also found to decrease away from the source region from 2.33t km−2 (dry deposition of 1.36t km−2 and wet deposition of 0.97t km−2) over the domain YES to 1.45t km−2 (dry deposition of 0.16t km−2 and wet deposition of 1.30t km−2) over the domain NWP. A large amount of the total dust deposition over the seas is contributed by wet deposition (more than 90%), causing a small decreasing rate of the total dust deposition with distance from the source region. The estimated dust deposition could adversely impact the eco-environmental system significantly in the downstream regions of the Asian dust source region, especially over the seas.
