Abstract:In this paper, we use the data of CIMISS and Zunyi monthly reports of 13 weather stations to collect the data of hail, gale and precipitation at the weather station of Zunyi from January 1, 1961 to December 31, 2017. From the aspects of hail diameter, hail time and space distribution, the relationship between hail and gale, the relationship between hail and precipitation, the spatial and temporal distribution characteristics of hailstone in Zunyi were comprehensively analyzed. The results show that the main hail is small hail in Zunyi, the probability of a big hail is small; the duration of hail is mainly short hail, and hail location less likely to hail several times a day; The number of hail days in Yuqing was the highest, Chishui was the lowest, the largest number of hail days occurred in the eastern part of Zunyi, followed by the central, western and northern parts, there is little likelihood of widespread hail. Hail concentrated in February to May, of which the largest in April, from a ten-day perspective, hail days were highest in early May; hail in Zunyi mainly occurred in the night, concentrated in the daytime at 14 o"clock to 20 o"clock;The annual and interdecadal variations of hail days are generally declining,the sum of hail days from 2011 to 2020 is likely to fall below the historical extreme; Hail and strong winds in the same place are less likely to appear on the same day. However, in the whole area of Zunyi, the probability of occurrence of hail and gale on the same day was as high as 74.23%; the hail diameter and rainfall show a weak positive correlation.
