Abstract:Based on the climatic data of ten years(1991─2000), the spatial-temporal characteristics of hailfall in North China are analyzed. The results show that: (1) The main hail zone appear in the shape of the letter T around the Yinshan mountain ranges and Taihang mountain ranges. (2)The annual variation appears a tri-peak form in the curve of dekad- or pentad-hail days evolution. (3) The daily variation of hailfall also has seasonal characteristics.
