| 摘 要： | 利用1951～2007年热带气旋、湖南降水资料,统计分析了登陆影响湖南的热带气旋时空分布,及造成的强降水特征.结果表明:57年中登陆影响湖南的热带气旋共161个,平均每年3个,主要出现在7～9月,影响热带气旋主要为台风或以上强度;影响湖南的热带气旋登陆地点以广东、福建最多,强度达强热带风暴或以上的热带气旋可造成极端暴雨降水,时间主要出现在8月.20世纪90年代以后暴雨强度呈加大趋势.

| Abstract: | Tropical cyclone and precipitation data from 1951 to 2007 are employed to perform statistical analysis on the characteristics of the landfalling tropical cyclones and related heavy rainfall affecting Hunan.The result shows that in 57 years,there are 161(about 3 per year) landfalling tropical cyclones affecting Hunan,most of which were Typhoon or above and occurred from July to September;The Hunan affecting tropical cyclones mostly landed in Guangdong and Fujian;The extreme rainstorms related to TCs equal/above severe tropical storm mostly occurred in August and the intensity of rainstorms increases significantly since 1990s. |
