Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.
