Atmospheric turbulence which induced by wind shear and/or convection is non-uniform anisotropic flows of high Reynolds and Rayleigh number[1].According to the mechanism of turbulence generation,atmospheric boundary-layer stratification can be classified into neutral,unstable(convective)and stable[2].Observations show that sandstorms and wind-blown sand mostly occur under unstable stratifications from afternoon to early evening[3].As the surface absorbs the solar radiation,the surface temperature increases and vertical convection develops,which enhances the momentum exchange between the upper and lower layers and hence increases the near surface wind speed and shear stress[4].
