Rainfall is one of the four main types.
Artificial Rain When the sky is covered with a rain cloud but it is not raining, artificial or man-made methods can be used to save the standing crop by drying it.
As well as the water problem can be alleviated.
Experiments for artificial rainfall are carried out by national institutes like the Indian Institute of Tropical Meteorology and other private institutes.
Sometimes silver iodide vapor is released over the clouds.
Experiments with artificial rain are very expensive.
Besides, it never gets the expected success.
In Gujarat, artificial rain is used by the agriculture department of the state government in times of drought.
