How is cloud seeding done?
Cloud seeding works by artificially encouraging clouds to produce rain.
One method involves planes fitted with flares loaded with salt crystals which are then fired into clouds.
As the cloud sucks up the crystals they attract tiny particles of water which collide and become heavier.
The water then falls as rain..
Is artificial rain expensive?
Now, our engineers at IIT Kanpur have developed the technology of producing artificial rain, which is much cheaper in comparison to China. … The technology developed by IIT Kanpur, however, will cost only Rs 5.5 crore to cover 1,000 square kilometres with artificial rains.”
Is silver iodide toxic?
Under the guidelines of the Clean Water Act by the EPA, silver iodide is considered a hazardous substance, a priority pollutant, and as a toxic pollutant. … If the toxicity manifests in pollution and illnesses, the effects may not be reversible.
How successful is cloud seeding?
Other recent studies have used computer modeling to estimate the increase in snowfall from cloud seeding. A 2014 study across two Wyoming mountain ranges found that cloud seeding could increase snowfall by 5 to 15 percent — but only when the right conditions for seeding were met, or during 30 percent of snow events.
What is the chemical used in cloud seeding?
silver iodide particlesCloud seeding adds small, ice-like particles to clouds. Usually, silver iodide particles are used. These particles act as additional condensation nuclei. Unattached supercooled water vapour molecules in the clouds condense around these particles.
How rain is formed?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. … Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
How cloud seeding makes it rain artificially?
Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere, providing a base for for snowflakes or raindrops to form.
Who invented rain?
The first standardized rain gauge was invented in 1441 in Korea. In 1662 the first tipping bucket rain gauge was invented in Britain by Christopher Wren and Robert Hooke. The first systematic rainfall measurements were done between 1677 and 1694 by Richard Townley in Britain.
Why is cloud seeding?
The idea behind cloud-seeding is to encourage more rain to fall from the cloud by clumping the water droplets together, which makes them heavier and more likely to fall.
When did cloud seeding start?
1946The first experiments with cloud seeding were conducted in 1946 by American chemist and meteorologist Vincent J. Schaefer, and since then seeding has been performed from aircraft, rockets, cannons, and ground generators.
Can cloud seeding cause hurricanes?
The reason that tropical cyclones have little supercooled water is that the updrafts within such a system are too weak to prevent water from either falling as rain or freezing. As cloud seeding needed supercooled water to function, the lack of supercooled water meant that seeding would have no effect.
How do you make man made rain?
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.
Does it ever rain in Dubai?
Dubai has a hot desert climate. Dubai has two distinct seasons – summer and winter. … Rainfall is scarce during the summer months, but the windy conditions ensure there are frequent dust storms. Temperatures regularly climb above 38 °C (100 °F) during this period and fall to around 26 °C (79 °F) overnight.
How do you make real clouds?
Make a Cloud in a BottleMaterials. Transparent glass jar. … Form the water vapor. Fill a jar with 2 inches (5 cm) of warm water and stir. … Form smoke particles. Ask an adult to light a match, blow it out and quickly drop it into the jar. … Cool it. … Watch the cloud appear. … Make it disappear. … The real deal.
Who invented cloud seeding?
Vincent J. SchaeferVincent J. Schaefer, a self-taught chemist who invented cloud “seeding” and created the first artificially induced snow and rainfall, died on Sunday at a hospital in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr.
Which chemical is used in artificial rain?
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide) and Liquid propane.
What are the side effects 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.
