Solid silver iodide is preferred as a nucleator for artificially stimulated rain because its crystal lattice parameters are close to those of ice, and for that reason are more effective than other salts in causing small ice crystals in clouds to melt.
Silver Iodide
silver iodide is sprayed on the clouds
silver iodide Agi
Chemicals like sodium iodide were initially used but now potassium chloride is preferred over sodium iodide as it has some side effects but then too even sodium iodide is still used.
Silver iodide is the primary compound, but there is nothing that will make it rain without fail, and it won't always do it where you want it.
Cloud seeding with Silver Iodide.
Silver iodide (AgI).
Seeding clouds with silver iodide or dry ice
The only known way to make rain is by physically seeding clouds, usually with silver iodide and dry ice. Traditional rainmakers do not actually have the ability to make rain.
There is no way to make rain without physically seeding clouds, usually with silver iodide and dry ice. Traditional rainmakers do not actually have the ability to make rain.
go to the Eart Science book. The airplanes can drop artificial ice nuclei into a cloud in an effort to produce rain. The other is to "seed" a supercooled cloud by dropping pellets of frozen "dry ice", into it.
by cloud seeding we can produced artificial rain .!!
