The extra water produced from cloud seeding can sit in water storages for multiple years. Pictured: Local residents wade through floodwater in Lismore, NSW. The silver iodide causes water droplets in the clouds to form ice crystals that become heavier and fall faster, releasing precipitation. On the other hand, I am also dedicated to the scale up of the production, reduce the cost, and the application of the materials. Dr. Zou: In the natural water cycle on the earth, the sun irradiates on the surface of our planet and the water on the surface is evaporated by the heat as the vapors.
