ABSTRACT
Three-dimension diagnostic and prognostic models were used for numerical simulation of cloud system accompanied the passage of a cyclone over Ukraine. The response of time and space distribution of cloud particle spectra, integral features and precipitation on changing of cloud and precipitation formation mechanisms (condensation, sublimation, collection by large drop and ice particles for droplets etc) was investigated. The nested and stretched grid was used to simulate the narrow band of heavy rainfall that frequently appeared ahead a cold front. The numerical experiments for different values of cloud condensation nucleus concentration were carried out for the above rainband. Comparison between spectra for different conditions was performed.
