The results display that there were more hail days in Ningxia from the 1960s to the 1980s. The hails mainly occur in summer and autumn, but the occurrence time is different in different regions. The hails in the area irrigated by the Yellow River in the north belong to the type of occurring frequently in summer, while the hails in the central and southern parts belong to the type of occurring frequently in late spring and early summer. The peak periods of the two types of hails differ by about one month. More than 90 percent of the hails occur between 12:00 and 20:00. The spatial and temporal distribution is generally characterized by more in the plateau and mountainous areas and less in the low plain and desert areas.
