中文摘要:

费用结构和闪电在二超级房间雷雨解除的时间、空间的特征 ofcloud-to-ground (CG ) 被分析了有高时空分辨率的三维的甚高频放射来源的基于的在数据由闪电分泌物生产了。当很多积极 CG 闪电分泌物正在发生在二雷雨时,结果显示在雷雨的主要部分(对流区域) 的费用结构是转换 tripole。积极 CG 闪电分泌物在雷雨的主要部分发生了并且从在雷雨的中间的部分定位的正电荷区域发源。当很多否定 CG 闪电分泌物正在发生时,否定 CG 闪电分泌物发生在雷雨的铁砧。费用结构由于在向铁砧区域的主要区域的费用结构的观点是在这个区域的转换偶极子。在铁砧的上面的部分定位的否定费用区域生产了很多否定 CGlightning 分泌物。不或少些,灯光的 CG 被在雷雨的更低的部分定位的费用区域直接生产。在雷雨的更低的部分的费用区域在它上面从费用区域为 CG 闪电的出现起一个重要作用。

英文摘要:

The charge structures and temporal and spatial characteristics of cloud-to-ground (CG) lightning discharges in two supercell thunderstorms have been analyzed based on the data of three-dimensional VHF radiation sources with high time and space resolution produced by lightning discharges. The results indicate that the charge structures in main part (convective region) of the thunderstorms were inverted tripole while a number of positive CG lightning discharges were occurring in the two thunderstorms. The positive CG lightning discharges occurred in main part of the thunderstorms and originated from the positive charge region located at the middle part of the thunderstorms. While a number of negative CG lightning discharges were occurring, the negative CG lightning discharges occurred in the anvil of the thunderstorm. The charge structure is inverted dipole in the region due to the slant of charge structure in main region toward anvil region. The negative charge region located at the upper part of anvil produced a lot of negative CG lightning discharges. No or less CG lighting was produced directly by the charge region located at the lower part of the thunderstorm. The charge region in lower part of the thunderstorm plays an important role for the occurrence of CG lightning from charge region above it.
