It is also known as cloud seeding. Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei. The usual intent is to increase precipitation, but hail suppression is also widely practiced. Silver iodide and dry ice are the most commonly used substances in cloud seeding.

Artificial rain is produced by spraying clouds with substances like Silver Iodide (costly) or cheaper ones like solid carbon dioxide (dry ice) or even finely powdered Sodium Chloride. This process is called seeding.

Often there are clouds, but no rain. This is because of a phenomenon called supercooling. The temperature of the cloud might be close to zero and there might even be crystals of ice in it.

The water vapour in the cloud does not condense to liquid water. The super cooling gets disturbed by spraying the cloud with the chemicals mentioned above, using a ...more

Silver iodide is sprayed on the cloud to make them cool then automatically water content in the clouds become waterdroplets and fall down to earth in the form of rain
it is called the artificial rain

Artificial rains are man made rains. Some chemicals were filled into the tanks in a plane & then chemicals were spread over the sky's of dried land. then the chemical reasts with the air & extract the moister from air.
These moister leads rain to happen

Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports. Cloud seeding can be done by ground generators or by plane.

Artificial rain is produced by spraying clouds with substances like Silver Iodide (costly) or cheaper ones like solid carbon dioxide (dry ice) or even finely powdered Sodium Chloride. The process is called seeding.

The process involved in artificial rain-making involves three easy-to-understand stages. The first stage is agitation. That is using chemicals to stimulate the air mass upwind of the target area to rise and form rain clouds.
The chemicals used during this stage are calcium chloride calcium carbide, calcium oxi ...more
