Man-made precipitation Definition Also known as artificial rain,the artificial method of increasing the clouds of ice or clouds of ice crystals and water droplets formed increased precipitation. Principle Whether natural or artificial rainfall rain cloud must have existed.Cloud is condensed from water vapor. Generally speaking,the vapor cloud plastic state relatively stable,easily precipitation,and artificial rainfall is based on the principle of such damage collagen stable state.
