Abstract:
All kinds of convective weather such as thunder storms, hail, torrential rain an d strong wind during warm season (from May to September) of recent 12 years in B eijing areas were statistically analyzed. It showed that the probability of conv ective weather is high. The climate probability of convection is 47.77% by conve ction days. The climate probabilities of strong wind, torrential rain and hai l are 27.29%, 10.84% and 6.29%,respectively. A majority of torrential rainoccurs from the second ten days of July to the first ten days of August. Howev er, hail commonly occurs in the second and the third ten days of June. The conve ctive weather often geographically occurs in northwest and northeast mountain ar eas and southwest mountain areas of Beijing. Whereas, it seldom occurs in center and southwest plain areas of Beijing. The torrential rain often occurs in northe ast mountain areas, central and southeast plain areas of Beijing, and it seldom occurs in northwest and southwest mountain areas. Mountain areas have more hail t han in the plain areas. Strong winds often occurs in northwest and northeast mou ntain areas. Torrential rain often occurs in the night. Hail of 76.72% occurs in the afternoon.
