For artificial stimulation of rain by AgI particle seeding, mere heating of AgI of electric heater or burner leaves as much as 20_??_30% of Ag by dissociation of AgI into Ag and I. To cope with this uneconomical process, addition of 10% Nal or KI to AgI is tried. The vaporising tem-perature being kept the same, this addition is found to double or more the number of effective ice nuclei and that the ice nucleation of the cloud becomes more effective while the weakening effect of ultraviolet rays of light is not appreciably enhanced by it.
