| 摘 要： | 利用宁夏地区24个国家气象观测站1961—2018年的逐日观测资料,对降雹时空分布特征进行研究。结果表明:(1)宁夏地区20世纪60至80年代为降雹多发期;(2)宁夏降雹整体上多发生在夏、秋两季,但不同区域发生时间又有所不同,北部川区降雹类型属于夏季频发型,中南部地区属于春末夏初频发型,两种类型降雹高峰期相差1个月左右;(3)9成以上的降雹出现在12:00—20:00;(4)空间分布总体呈现为高原和山地多,平原和沙漠少的特征,主要降雹区域集中在六盘山山脉所在的固原地区。

| Abstract: | Based on hail data from 24 meteorological stations in Ningxia during 1961-2018, the spatial and temporal characteristics of hail days are studied. 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. |
