Abstract：using the hail data from 2021 to 2025 in Guizhou Province,the temporal and spatial distribution characteristics of hail in this period were analyzed,and combined with the data of the new generation weather radar observation radar,the characteristics of various parameters in the evolution process of hail cloud monomer were analyzed,and the temporal and spatial distribution characteristics of hail in Guizhou in recent five years and the early warning index of winter hail were obtained.The results showed that the number of hail days first increased and then fell in Guizhou from 2021 to 2025,all parameters of the hail cloud cell exhibited pronounced "jumps"before hailfall.In this case,typical hail signatures such as Vnotch,high overhang,echo dome,and hook echo,along with "twostage jumps,"were observed.H18 dBZ＞12 km,Z＞55 dBZ and VIL≥20 kg/m2 are good indicators of hail in spring.The results can provide reference for hail warning and weather modification in Guizhou.
