Abstract

Results of experimental investigations of an influence of the model hydrometeors on an electromagnetic radiation of the discharge phenomena initiated in an artificial thundercloud have been presented. It was established that the characteristics of an electromagnetic radiation of the cloud discharges initiated by the model hydrometeor groups in an artificial thundercloud depend on the location of the cells of a different polarity relative to the ground, as well as on the place of an introduction of the large hydrometeor arrays into the gap between the cells. It was determined that the character of the registered electromagnetic radiation of the discharge phenomena initiated by the model hydrometeor groups in the artificial thundercloud was close to the character of the powerful bipolar impulses of very high frequency registered for the cloud discharges and during the beginning stage of a downward lightning formation. It was proposed that the arrays of a large hail in a thundercloud could provoke the discharge phenomena significantly modifying the characteristics of the electromagnetic radiation of the cloud discharges. It was experimentally shown that the introduction into the artificial thundercloud of the model hydrometeor groups combined in a common system by the dielectric string can sufficiently decrease a power and the duration of the impulses of an electromagnetic radiation of the initiating discharge phenomena.

模型水汽对人工雷云中放电现象电磁辐射的影响

摘要

提出了关于模型水凝物对人工雷云中引发的放电现象的电磁辐射的影响的实验研究结果。已经确定，由人工雷云中的模型水凝物群引发的云放电电磁辐射的特征取决于相对于地面极性不同的细胞的位置，以及引入水的位置。大型水凝物阵列排列在单元之间的间隙中。可以确定，由模型雷雨流星群在人工雷云中引发的放电现象的配准电磁辐射的特征与为云放电和初始阶段所记录的非常高频率的强大双极脉冲的特征接近。向下的闪电形成。有人提出，雷云中的大雹会激发放电现象，从而显着改变云放电的电磁辐射特性。
