Seeding Clouds to Spout Rain

Cloud seeding is a method of enabling inefficient clouds to bring rain, or enhance rainfall from a seedable cloud by introducing seeding material. The secondary effect of evaporation from falling precipitation improves the thermodynamic efficiency of the environment to form fresh convective clouds and more rain. This principle is used to enhance rainfall and reduce pollution. Two types of seeding—‘ground’, using generators and rockets, and, ‘aerial’ seeding using aircraft are possible. Based on the type of cloud to be seeded...
