An analysis is made of the statistical characteristics of the spatial distribution, annual distribution and variation, and daily change of hailing days, as well as hailing duration, with the hail data of recent 46 years from 20 meteorological stations in Ningxia and NCEP/NCAR reanalysis data. The analysis shows that hailing days reached the peak in the 1980s; hail storms occurred mostly from April to September; the southern Ningxia was the most frequently attacked area by hail storms; the number of hailing days, the area of hailing in the same day, hailing duration, and the maximum diameter of hailstones all show a decreasing trend from the 1990s.
