Influence of hydrometeors on formation of discharge between artificial thunderstorm cell and ground

Application of the artificial thunderstorm cell of negative or positive polarity with the model hydrometeor array could help on the clarifying of problem of the lightning initiation in thunderclouds. Results of experimental investigation of the influence of the hydrometeor array disposed inside the artificial thunderstorm cell and near its boundary on the discharge initiation and propagation between the cloud and the ground have presented. Peculiarities of the discharge formation on the hydrometeor array in the negatively and positively charged aerosol clouds have analyzed. Application of the received results to the natural thunderstorm situation has discussed.
