Can you make artificial rain?
Can you make artificial rain?
According to the clouds’ different physical properties, this can be done using airplanes or rockets to sow to the clouds with catalysts such as dry ice, silver iodide and salt powder, to make clouds rain or increase precipitation, to remove or mitigate farmland drought, to increase reservoir irrigation water or water …
Why is silver iodide used for 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.
What are the dangers of cloud seeding?
Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns, rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
Is silver iodide harmful?
“silver iodide is toxic and must be handled with care.”
How can I get rain naturally?
How to (Try to) Make It Rain
- Seeding the Sky. The most widely used weather-modification technique is probably cloud seeding, which involves priming clouds with particles of silver iodide.
- Rain Rockets. Airplanes aren’t the only way to seed clouds.
- The Atmosphere Zapper.
- Ice-Breaking Booms.
- Riding the Lightning.
Which country invented cloud seeding?
The cloud-seeding operations were initiated in the late 1990s in the UAE. By early 2001 these operations were being conducted in cooperation with the National Center for Atmospheric Research (NCAR) in Colorado, USA, the Witwatersrand University in South Africa and the US Space Agency, NASA.
Which compound of silver is used in cloud seeding?
Silver iodide or dry ice (solid carbon dioxide) is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase rainfall through the ‘cold rain’ process. Scientists say that the weather modification process can increase the rainfall by 15-24 per cent on an average.
Is silver iodide a heavy metal?
Abstract. 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.
What is the use of silver iodide?
Silver iodide or dry ice (solid carbon dioxide) is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase rainfall through the ‘cold rain’ process.
What is the Colour of silver iodide?
yellow
Silver iodide is an inorganic compound with the formula AgI. The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration.
How is silver iodide used in artificial rain?
Silver iodide acts as trigger or hook for the seeded cloud to precipitate. The chemical blends with the cloud and induce the freezing cloud to release it in the form of water. With such function, silver iodide is a chemical used in artificial rain. Another chemical needed in cloud seeding to create artificial rain is potassium iodide.
What happens when you put silver iodide on a cloud?
This image explaining cloud seeding shows the chemical 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 to the introduced chemicals.
Are there any health effects of silver iodide?
Moreover, a key manufacturer of silver iodide for weather modification, Deepwater Chemicals, warns of potential health effects of silver iodide in their Material Safety Data Sheet as follows:
How many rain samples per year to test for silver?
If PGCD can not control where the seeded clouds dumps water, how can they take only two rain samples per year to test for silver concentrates of the clouds they seeded? At least it is an admission that silver toxicity is an issue. Such misleading statements based on faulty data are not uncommon to the PGCD.
