ABSTRACT:
A method of cloud seeding for precipitation enhancement comprises releasing hygroscopic seeding particles from a seeding flare 10. The particles are obtained by burning, in the flare, a pyrotechnic composition which includes, as an oxidizing agent, a compound selected from the group consisting in potassium chlorate and potassium perchlorate. The particles are allowed to enter a suitable cloud formation. The particles act as seeds or nuclei for precipitable water drop formation, thereby to enhance precipitation from the cloud formation.
