Yellow dust events mainly occur in spring time over East Asia. This is the phenomenon in which sand and soil particles raised by dust storms are transported and make the atmosphere turbid. Major sources of yellow dust are located in arid and semi-arid regions in East Asia. Dusts have various impacts on the environment and human society. Mineral dusts affects the radiation balance through their scattering and absorbing solar and thermal radiation as well as affecting the atmospheric composition through their chemical reaction in the air. Furthermore, soil particles in the air are damage human health. To investigate mechanisms of yellow dust emission and its impacts, this study takes the wind erosion in desert region, dust transportation to proximal regions, and the health effects of air condition.
