Artificial rain, or cloud seeding, is a technique used to induce precipitation in areas experiencing drought or low rainfall.
It involves the introduction of substances such as silver iodide, potassium iodide, or salt into clouds, serving as nuclei for water droplets to form.
These substances promote the formation and growth of cloud droplets or ice crystals, encouraging them to combine and become heavier.
As these droplets or crystals gain mass, they fall from the cloud as rain, simulating natural precipitation.
The efficacy of cloud seeding can vary based on atmospheric conditions, cloud types, and the specific seeding materials used.
It works by enhancing or mimicking the natural processes that lead to rain, accelerating the droplet growth and precipitation process.
Used in agricultural regions, reservoir management, and areas where additional rainfall is needed for various purposes.
While it’s been used for decades, its effectiveness and long-term environmental impact are subjects of ongoing scientific research and debate.
Cloud seeding is practiced in various countries around the world, but its widespread adoption depends on local regulations and effectiveness.
There are discussions regarding the ethical implications of manipulating weather systems and the unintended consequences it might bring to the environment.
