Abstract
In this paper, physical effects caused by a crystallizing reagent in the deep stable cloud, which was developing on July 7, 2006 in Alberta, Canada, are analysed. The ultimate goal of that experiment was reducing economical losses caused by hail. The radar data analysis and numerical modeling showed that use of the reagent allowed significant reducing the hail particles size.
