Cloud seeding is the process of condensing clouds to create rain, particularly in areas where condensation is unlikely.
The process involves dropping particles containing super-cooled water into clouds, which have temperature lower than the normal freezing temperature.
When these particles turn heavy and remain suspended in the air, they fall, melting on their way down to create rain.
Cloud seeding in dry areas is made possible by seeding the atmosphere with chemicals, such as silver iodide or dry ice, to form ice crystals.
The “seeds” are carried into the atmosphere by plane or by spraying from the ground.
