Abstract
Results of the experimental simulation of lightning initiation processes in thunderclouds by large hydrometeor arrays using artificial clouds of charged water aerosol of negative and positive polarity are presented in this paper. A significant influence of the hydrometeor arrays on the discharge initiation and propagation between the charged cloud and the ground is shown. It is found that cloud polarity has a significant influence on the probability of discharge initiation by the hydrometeor array. It is established that hydrometeors have the most pronounced influence on the discharge initiation in positively charged aerosol clouds. Character types of the discharge phenomena initiated by the hydrometeors in the clouds of negative and positive polarity are found: cloud discharges, channel discharges, and diffuse discharges. It is established that the characteristic frequency ranges in the wavelet spectrum of electromagnetic radiation of such discharge phenomena initiated by hydrometeors have greater values for a negative polarity of a cloud than for a positive one. It is found that the characteristics of the current impulse of the main stage of the discharge between the cloud and the ground forming with the participation of hydrometeors differ from the analogous characteristics for cases in which hydrometeors are absent in the gap between the charged cloud and the ground. Thus, using artificial clouds of charged aerosol opens new possibilities for investigation of the processes of lightning initiation in thunderclouds.
