摘要
凉山彝族自治州会东县是全国主要的烤烟生产区,每年6~10月极易发生冰雹灾害,通过对地形地貌和每年6~10月天气系统的分析,找到了会东县的主要孕灾因子,分析了会东县高炮作业的最佳方法。结果表明:会东县的冰雹天气系统有四种,分别是高空冷平流型、高空低槽型、高空强辐散型和暖湿气流型;会东县的冰雹孕灾环境有两个,一个是地形地貌,一个是6~9月的暴雨天气;会东县冰雹天气类型为本地型约24%,输入型约19%,局地型约57%,高炮作业挥洒碘化银是会东县主要的防雹方式,通过这种防雹方式,烤烟生产受冰雹灾害的影响会大大减小。
Huidong County of Liangshan Yi Autonomous Prefecture is the main flue-cured tobacco production area in China,the hail disaster is prone to occur from June to October every year.Through the analysis of topography and weather system from June to October every year,the main disaster-inducing factors in Huidong County are found,and the best method of artillery operation in Huidong County is analyzed.The results show that there are four hail weather systems in Huidong County,namely,high-altitude cold advection,high-alti-tude low trough,high-altitude strong divergence and warm-wet airflow.There are two hail disaster environment in Huidong County,one is topography,the other is rainstorm weather from June to September.Hail weather types in Huidong County are about 24%of the local type,19%of the input type and 57%of the local type.The main hail suppression method in Huidong County is the spraying of silver iod-ide by antiaircraft gun operation,through this way,the influence of hail disaster on flue-cured tobacco production will be greatly reduced.
