Wind-blown sand and dust storm are typical gas-solid two phase flow occur in high Reynolds atmospheric boundary layer turbulence. Better understanding, accurate prediction and effective controlling of wind-blown sand and dust storm all rely on knowledges of sand/dust particle movement, and therefore on the research results on high Reynolds wall turbulence:The driving force of particle movement. After a briefly review on high Reynolds wall turbulence and sand/dust storm researches, the Qingtu Lake Observation Array (QLOA) established in Minqin county was introduced in detail. Preliminary results achieved in the light of observed data and outlook were described.
