CUMULUS CONGESTUS CLOUDS AS SOURCE OF POLLUTANTS IN THE UPPER TROPOSPHERE

M. K. Zhekamukhov and A. M. Abshaev

A simple model of acid rain origination and contaminant transport from the surface air layer to the upper troposphere is considered. It is found that atmo¬spheric contaminants are very efficiently absorbed by cloud droplets inside cumulus congestus clouds; the smallest droplets are the most numerous and the hardest to remove. From calculations, it is concluded that the contaminating effect of acid rains on vegetation in the case of heavy showers is slightly less than in the case of less heavy precipitation.
