Abstract
Taking account of variation of water vapor content and temperature in an air parcel, a new model for the size estimation of the cloud droplets condensed on composite CCN, whose constituents are waterinsoluble dust of kernel and water-soluble substance of coat, has been developed. New model is constructed by coupling chemical potential equilibrium with mass and heat conservation equations. Variations of the droplet size and the individual and populational amounts of droplet with the dust size are simulated numerically. The numerical results show that the larger dust size is, the more the droplet size and the condensation amounts increase.
