| 摘 要： | 为进一步研究闪电活动特征,利用ADTD闪电定位资料、静止气象卫星葵花八号等气象资料,对2016年7月20日一次强对流天气过程中的闪电活动进行分析,探讨闪电活动与LAPS云分析场的关系,探索地闪资料在LAPS云分析中的应用。结果表明,地闪活动集中区域对应着强降水区,降水峰值与闪电活动峰值为重合的现象;大部分闪电发生处于对流云系影响范围之内且对应了中高层次的云顶性质;在LAPS云分析场中地闪活动频繁的区域,云柱更为厚实且出现了更为强烈的上升运动,水汽也更为充沛,闪电活动与积雨云的对应关系不仅可以反向验证卫星反演的云分类产品,也可以对LAPS三维云场进行订正和调整,并作为多源数据融合云分析的补充资料。

| Abstract: | For a further study on the properties of Lightning activity and to explore the usage of lighting data in LAPS cloud analysis, this thesis analyzes the lightingactivity of a strong weather process on 20 July 2016 by applying the ADTD lighting location data and the Himawari-08 meteorological satellite data,and the relationship between lighting activity and the LAPS cloud analysis field.The Major conclusions are as below:the lightning concentrated areasparallel to the large value area of accumulated precipitation, the rainfall peak values are coincident with lightning peak values;The cloud inversion products statistical results showed that the lightning indicates that the occurrence and development of cumulonimbusand the higher Cloud-top property;in the frequent lightning area, clouds are thicker and the vertical distribution of water vapor and the vertical velocity shows that the region has a strong upward motion, lightning activity parallels with cumulonimbus, not only can it verify cloud classificationinversion products but also revise and adjust 3 D cloud field from LAPS cloud analysis, and the lightning data could be a supplementary of LAPS multi-source fusion. |
