Artificial rain, known as cloud seeding, is a weather modification technique used globally to induce rainfall. It involves spraying substances like silver iodide, potassium iodide, or dry ice into moisture-rich clouds using aircraft. These chemicals serve as nuclei that help water vapor condense into raindrops. The method can increase rainfall by 10–30% and is particularly beneficial in drought-affected areas and for reducing urban pollution. However, it is effective only under specific conditio
