Laser-induced Mist and Particle Formation from Ambient Air: A Possible New Cloud Seeding Method

A new method of water condensation is reported. A UV laser induces seed formation from the air itself for water mist or ice particles depending on the temperature of the ambient air. The possible mechanism of this new phenomenon is proposed with photochemical radical formation and following reactions. This may offer the new prospect of a simple and environmentally harmless way to create artificial rain and snow.
