A method of making a cloud give up its moisture as rain, especially by releasing particles of dry ice or silver iodide into cold clouds. Dry ice freezes water droplets in the cloud, turning them into nuclei for the formation of raindrops. Silver iodide particles are used because they have a crystal structure similar to ice and can also serve as nuclei for raindrop formation.
