The escalated hazards caused by yellow dust, associated with environmental degradation in northern part of China, have attracted increasing attention in recent years. Dust has various direct impacts on environment and human society: Dust storms have killed hundreds of people in the recent decade; The suspended particulates is harmful to the human respiratory system. On the other hand, dust neutralizes the acidity of the rainfall in East Asia. To evaluate this complex phenomenon, the series of dust events, such as dust emission, transportation, deposition and impact, should be understood comprehensively. This study revealed the vulnerability to wind erosion for various environments in arid and semi-arid regions in East Asia, and the climatological fluctuation in the area that can clearly explain the recent increase in the aeolian dust in the proximal regions. The countermeasures to the yellow dust phenomena of long-term basis can be established by integrating these results.
