Artificial rain, also known as cloud seeding, is a weather modification technique that aims to enhance precipitation. This process involves dispersing substances like silver iodide or sodium chloride into the atmosphere, which encourages clouds to produce rain. By targeting specific clouds, scientists can potentially increase rainfall in areas experiencing drought or water shortages. The technique has been used in various countries, including China and the United States, to improve water supply for agriculture and manage water resources. While cloud seeding can help alleviate drought conditions, its effectiveness and environmental impact are still subjects of ongoing research and debate.
