'Cloud seeding'

Artificial or controlled rains are created through ‘cloud seeding,’ which includes adding certain chemicals to the clouds.

Which chemicals are used?

Chemicals like silver iodide, potassium iodide, and dry ice are dispensed in the troposphere. This binds water vapour and creates rainy clouds.

Is it successful?

The effectiveness of artificial rain is not assured. It heavily depends on the presence of moisture in clouds and appropriate wind patterns.
