雷电天气监测与雷电回波特征分析

为了解决雷电天气的实时监测与雷达回波的识别问题。文章利用2015-2018年雷电监测数据和雷达拼图数据,对江西宜丰和上高县的雷电天气和雷达回波特征等进行统计和对比分析,得出近年来,宜丰和上高县雷电活动次数逐渐增多,强度逐渐增强;飑线回波带是造成宜丰和上高县雷电的重要回波系统,尤其是回波带出现弧形弯曲,形成弓状回波带时,雷电天气更加明显;超级单体回波是造成宜丰和上高县区域雷电的重要回波系统;雷电监测可以通过“宜丰雷电监测产品自动显示与预警系统”发布。

Lightning weather monitoring and lightning echo characteristics analysis

To solve the problems of real-time monitoring of lightning weather and identification of radar echoes,and using the lightning monitoring data and radar mosaic data from 2015 to 2018,the lightning weather and radar echo characteristics of Yifeng and Shanggao county in Jiangxi province are statistically compared and analyzed.The results show that the frequency and intensity of lightning is increasing gradually in Yifeng and Shanggao in recent years.The squall line echo zone is an important echo system which causes the lightning in Yifeng and Shanggao.The lightning weather is more obvious when the echo zone is curved and forms the bow echo zone.The supercell echo is an important echo system causing lightning in Yifeng and Shanggao.The lightning monitoring can be released through the Automatic Display and Early Warning System of Yifeng Lightning Monitoring Products.
