| 摘 要： | 2008年11月2日连续性的大雨、暴雨引发了云南楚雄州特大地质灾害,造成巨大生命财产损失。文章利用高空探测资料、测站雨量、加密自动站雨量、卫星云图等资料分析了诱发楚雄州"11.02"特大滑坡泥石流灾害的气象成因。结果表明:除了地质地貌自然原因外,楚雄州出现历史罕见秋季连续强降水天气过程是造成这次灾害的前期气候背景;中尺度辐合天气系统、充沛水汽输送及辐合、高低空急流、中低层切变导致的11月1日20:00至2日20:00楚雄州暴雨是引发"11.02"滑坡泥石流灾害的直接气象原因。

| Abstract: | A continuous severe rain occurred on 2 November 2008 in Chuxiong,Yunnan Province,which initiated an exceptional big geological disaster and created a huge loss of life and property. By means of the data of MICAPS 3,conventional meteorological rainfall,intensive unattended station rainfall,and satellite cloud pictures,the meteorological causes of the event are analyzed.The results indicate that besides natural causes such as geological condition and landform,the historically rarely seen severe rainfall is a ... |
