Abstract
Thermodynamic models of extremal intermediate states (MEIS) are used to describe the features of the formation of nucleating drops and aerosol watering in the atmosphere. Advantages of MEIS in describing phase transitions in multi-component systems are shown. Results of the calculation of the equilibrium (thermodynamically most probable) drop radius are discussed for different ratios of the soluble to insoluble components of the condensation nuclei. The proposed approach allows numerical investigation of the effect of meteorological conditions on microphysical characteristics of haze, clouds and fog. Theoretical substantiation of size distribution of the aerosol of different origin will allow estimating possible anthropogenic effect on optical characteristics of the atmosphere, which are one of the basic climate-forming factors.
