Summary

In this paper the theoretical model of cloud spectrum formation process is built in which spectrum formation and its development are followed by and these observations find no contradictions, beginning with air ascent containing condensation of nuclei and up to large drop formation falling out off the cloud. Both the obtained results of velocity spectrum formation and the form of distribution function corresponds to the direct observations. The model does not use any empirical relations and empirical regularities; it is free from arbitrary suppositions and assumptions which are not examined by experiments, and the number of parameters in it is limited by ones (vertical velocityU z, turbulent diffusion coefficientK z and two parameter distribution function of nucleus condensation with super-saturation). First in the developed theory the principal contradictions not allowing till now to connect together condensational and coagulation stages of cloud spectrum development are overcome.
