%X Based on the first part of this study, five sub-category divisions are made according to generally defined terminology of hail and graupel in order to simplify analyses of the 21 hail categories in the hail category model. These five re-divided sub-category divisions are: small ice particles (D< 1 mm), graupel and hail embryos (1 mm< D< 5 mm), small hailstones (5 mm< D< l0 mm), typical hail- stones (10 mm< D< 25 mm), and large hailstones (D > 25 mm). The characteristics of distribution and evolution of each category of ice particles as well as the size distribution of hail and graupel in the re- gions of overhang, anvils, up-and down-draft are presented. The mechanism of kinematical recirculation growth of ice particles of each category and the contribution to the formation and growth of hail are discussed. Comparisons of hail size distribution from hail category model and that from Marshall-Palmer assumption are also shown at the end part of this paper.
