摘要

Dust storm events, especially those associated with strong winds, are immediately dangerous, and have long-term harmful effects. During a dust storm event, dust in the near-surface atmospheric layer decreases visibility, and changes local meteorological parameters. In this paper, we analyzed levels of near-surface turbulence during and outside a dust storm event and found differences in the degree of turbulence, with wind speed increasing and amounts of windblown sand greatly increasing air turbulence during the dust storms compared with the corresponding values on a sunny day. In addition, the wind profile during the dust storm deviated from the normal profile and became more complex. In the near-surface atmospheric layer, sand and dust flux during the dust storm also differed from those on a sunny day.
