Vertical turbulent dust aerosol fluxes are determined on the basis of measurements of fluctuations of the content of aerosol particles and the vertical component of the wind velocity for a desertified territory of Astrakhan oblast. The normalized flux or the uplift velocity of the dust aerosol reached 5 cm/s. It is found that the vertical turbulent aerosol flux is significantly affected by convective-related variations in the horizontal and vertical components of the wind velocity. It is shown that the daily variability of the uplift velocity of the aerosol agrees with that of the turbulent heat flux and that the mass dust aerosol flux is correlated with a maximum particle size of ~1.5 µm.

沙化区沙尘气溶胶湍流

垂直湍流尘埃气溶胶通量是根据对阿斯特拉罕州沙漠化地区气溶胶颗粒含量波动和风速垂直分量的测量确定的。归一化通量或尘埃气溶胶的上升速度达到 5 cm/s。发现垂直湍流气溶胶通量显着受风速水平和垂直分量中与对流相关的变化的影响。结果表明，气溶胶抬升速度的日变化与湍流热通量的变化一致，并且质量尘埃气溶胶通量与最大粒径约 1.5 µm 相关。
