Abstract: Based on the past research works we theoretically analyzed the formation mechanism of heavy dust storm and discussed the action of atmospheric strong advection to heavy dust storm (black wind). Then, we systematically explained the dust wall s character of heavy dust storm weather from physics aspect. Besides, we have summarized the scale and the vertical distribution of atmospheric particles in heavy dust storm; have qualitatively evaluated the climatic effect of dust storm from direct or indirect aspects, and from short-term or long-term aspects. Finally, we discussed some key scientific problems in dust storm research.

Key words: heavy dust storm, formation mechanism, atmospheric convection, dust wall, climatic effect
