【摘要】 通过对雷击易发区的调查,对气候、可燃物、火源种类等特征进行相关分析,结果表明:每年4月下旬至5月初为雷暴发生期,5月份以后强对流天气进一步增强,进入5月中旬后,为干雷暴发生最为频繁时段也是极易发生林火的危险时期。安装雷电监测系统,可以探测雷电发生的时间、方位、密度和强度等雷电特性;结合气象雷达和卫星资料,分析引发森林火灾的可能位置,作出预报。更多还原

【Abstract】 By means of the investigation of thunder areas in danger,features vegarding with thunder such as weather,combustible material,and source of fire category are analyzed in this paper.The results show that thunder occurs annually from the end of April to the beginning of May,and after May the strong convection weather strengthens further.After mid-May,dry thunderstorm occurs very often and it is also the dangerous period of arising forest fire.Thunder characteristics such as occurrence time,directions,and density and strength etc.can be detected by installing the thunder monitoring system.Combined with the weather radar and satellite data,the possible position of forest fire caused by thunder could be analyzed and forecasted.更多还原
