Which rain is created by cloud seeding?
This image explaining cloud seeding shows a substance – either silver iodide or dry ice – being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation upon the introduced material.
What are the side effects of cloud seeding?
Does Cloud Seeding Have an Impact on Health and the Environment? So far, experts haven’t found any harmful effects of cloud seeding with silver iodide on the environment. The concentration of silver in a storm from cloud seeding is far below the accepted limit of 50 micrograms per liter.
How does silver iodide make rain?
The crystals grow rapidly, drawing moisture from the surrounding water droplets, until their weight causes them to fall. While falling, the crystals may melt and join with small liquid water droplets; they may then form into raindrops in a manner similar to the ‘warm rain’ process.
What is the procedure of cloud seeding?
Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding adds small, ice-like particles to clouds. Usually, silver iodide particles are used. These particles act as additional condensation nuclei.
Why don’t they cloud seed in California?

How toxic is silver iodide?
The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. The ease with which Ag forms insoluble compounds, however, reduces its importance as an environmental contaminant. Ag is not likely to concentrate to harmful levels through either terrestrial or aquatic food chains.
What does silver iodide do to humans?
Prolonged exposure to iodides may produce iodism in sensitive individuals. Symptoms could include skin rash, running nose and headache. Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
What does silver iodide do to the human body?
What states use cloud seeding?
Within the past two years, Idaho, Utah, Colorado, Wyoming, and California have expanded cloud seeding operations, with seeding a key plank in the Colorado River Basin Drought Contingency Plan.
Is silver iodide cancerous?
The US Public Health Service claims there is a negligible environmental impact by cloud seeding. That said, silver iodide when studied in labs is a different story all together and is indeed toxic and dangerous. This same study says that silver is not known to be carcinogenic to humans.
Why don’t we cloud seed in California?
Where is cloud seeding used in the United States?
What happens to silver iodide in cloud seeding?
When storm systems move through one of our cloud seeding project areas, a solution containing a small amount of silver iodide is burned from ground-based generators or released from aircraft. Upon reaching the cloud, the silver iodide acts as a condensation nuclei to aid in the formation of snowflakes.
