Results of the experimental investigations of the influence of the model hydrometeor arrays on the characteristics of the electromagnetic radiation of the channel discharges between the system of the artificial thunderstorm cells of a negative or positive polarity and the ground have been presented in the paper. Parameters of the impulses of the electromagnetic radiation registered by the wideband plate antennas for the first and subsequent return strokes are under a consideration. Significant influence of the array of the large model hydrometeors on the probability of a subsequent stroke initiation and on the parameters of the corresponding electromagnetic radiation pulses has been established and discussed. Found dependencies between the characteristics of the current impulse of the first and subsequent return strokes from the system of the negative and positive artificial thunderstorm cells and the parameters of the impulses of the corresponding electromagnetic radiation have been analyzed. Comparison of the received results with processes of the electromagnetic radiation of a natural lightning has fulfilled.
