Influence of model hydrometeors on the final stage of a discharge from an artificial charged water aerosol cloud

The characteristics of the final stage of a discharge between an artificial negatively charged water aerosol cloud and the ground in the presence of large model hydrometeors are studied experimentally. With hydrometeors present in the discharge gap, the final stage of the discharge becomes much weaker than without hydrometeors. The spectral characteristics of the final stage of the discharge between the cloud and ground are obtained by processing the current and electromagnetic radiation of the discharge with wavelet analysis. It is found that, in the presence of model hydrometeors, the maximal frequency of the discharge current and the maximal intensity of the discharge radiation at the final stage are several times lower than without hydrometeors. Correlations between the current and spectral characteristics of the discharge at its final stage with and without hydrometeors are found.
