Vertical distribution of grain-size parameters of drifting particles during sand storms in the Taklamakan desert, Central Asia

Auteur(s) et Affiliation(s)



Description :
The vertical distributions of grain-size parameters of drifting sand flux during sand storms in the Taklamakan Desert, were investigated through field observation and laboratory wind-tunnel tests. The results show that grain-size parameters of the drifting sands near the ground surface are similar to those of the source deposits. Regional differences in the vertical distribution of grain-size compositions are affected by source deposits, wind speeds, and transport rates, but source has more influence on the sorting of the drifting material that wind velocity.
