Abstract

Application of the artificial clouds of charged water aerosol capable to initiate discharges inside clouds and between cloud and ground could help on the solving of problem of separation of the lightning intracloud and ground discharges, and establishment of connections between the parameters and the spectral characteristics of discharge current impulses and its electromagnetic radiation. Results of analysis of spectral characteristics of discharge from artificial thundercloud and radiation created by them in near field using two kinds of wavelets are presented. Characteristics frequency ranges for different stages of discharge formation and its radiation are analyzed. Comparison between the discharge current parameters and the parameters of its electromagnetic radiation and wavelet characteristic frequencies has been fulfilled. Application of received results to the analysis of electromagnetic radiation signals registered during the different stages of lightning is discussed.
