Peculiarities of electromagnetic radiation spectrum of discharges initiated by hydrometeors between artificial thunderstorm cell and ground

摘要

Results of experimental investigation of the influence of the hydrometeor array disposed inside the artificial thunderstorm cell and near its boundary on the spectral characteristics of spark discharge between the cloud and the ground and its electromagnetic radiation have presented. Peculiarities of the Fourier and wavelet (wavelet “Mexican hat”) electromagnetic spectrum of discharges forming on the hydrometeor array in the negatively and positively charged aerosol clouds have analyzed. Application of the received results to the electromagnetic radiation from discharge phenomena in natural thunderclouds has discussed.
