Modeling the convective cloudiness and its impact on the atmospheric gaseous composition

A combined three-dimensional numerical model of convective cloudiness with detailed microphysics and a model of the transport of atmospheric trace gases with gas- and aqueous-phase chemistry were developed. We consider the main physical mechanisms responsible for the formation of midsized droplet cl...

Description
Summary:A combined three-dimensional numerical model of convective cloudiness with detailed microphysics and a model of the transport of atmospheric trace gases with gas- and aqueous-phase chemistry were developed. We consider the main physical mechanisms responsible for the formation of midsized droplet clouds and the transport of gases with differing solubility therein. Test numerical calculations were performed to investigate the sensitivity of the cloud model to variations in input parameters, as well as the variability of the ion composition of cloud drops with regard to their size distribution. The results of numerical calculations are presented with a preliminary analysis.
