运用2000～2005年湖南省内244个强对流天气资料,统计分析了湖南省强对流天气的时间、地域分布特征,结果表明:湖南省强对流天气多在春、夏季出现,72%的强对流天气出现在夜间,其中冰雹、短时强降水出现在山区的频数大于平原,而大风在平原地区出现平均频数大于山区.通过分析强对流天气个例各气压层形势场的特点,结合卫星云图和雷达资料,将湖南省内强对流天气划分为5种类型:地面冷锋型、副高边缘型、地面倒槽型、静止锋型、东风波影响型.

Based on 244 samples of severe convective weather data from 2000 to 2005 in Hunan Province, statistical analysis of spatial and temporal distribution characteristics of severe convective weather was given in this paper. Results showed that the severe convective weather usually appeared in the spring and summer in Hunan, 72% of severe convective weather occurred in the evening, the frequencies of occurrence of the hail and Short-term heavy rainfall in the mountains was greater than which in the plains. However, the strong wind weather was contrary. The severe convective weather in Hunan Province was divided to 5 types: ground cold front,subtropical high edge, surface trough, stationary front,the impact of Easterly wave.
