英文摘要	The vertical turbulent dust aerosol (DA) and heat fluxes are determined on the basis of measured fluctuations of the components of the wind speed, air temperature, and concentration of aerosol particles on a desertified territory of Astrakhan oblast during intermittent DA emission. The temporal variability of the horizontal and vertical components of the wind speed, air temperature, and concentration of aerosol particles is characterized using spectral analysis. It is shown that the intermittent DA emission is caused by low-frequency convective-related variations in the horizontal component of wind speed if the threshold saltation speed is exceeded. The significant differences in the spatiotemporal variability of vertical heat and DA flux are revealed. The 30-min average values of heat (90-158 W/m(2)) and DA (7.2-27.5 cm(-2) cm(-1)) fluxes, as well as the rates of heat (14-21 cm/s) and DA (10-16 cm/s) removal, are calculated.
