Has Cloud Seeding Been Successful?

Can cloud seeding be used to reduce rain?

The use of cloud seeding is very controversial.

Some people say it isn’t worth the resources, because even the most dramatic rainfall increases only amount to 5-20%.

If it is done incorrectly, it can even reduce the amount of rain that might have fallen by dissipating clouds..

Can artificial rain be created?

For the uninitiated, cloud seeding or weather modification is an artificial way to induce moisture in the clouds so as to cause a rainfall. In this process, either silver iodide or dry ice is dumped onto the clouds by using an aircraft or an artillery gun which leads to a rain shower.

Why is it raining so much in Dubai?

Dubai relies heavily on expensive and power-hungry processes like desalination for most of its water, and there’s little doubt that fresh water rain takes some of the pressure off. As an added bonus, it also lowers the temperature.

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.

Does clouding cause wind?

Cloudseeding is the technique of inducing rain from a cloud, usually by dropping suitable particles into clouds containing supercooled water in an attempt to cause them to dissipate, modify their structure, or alter the intensity of associated phenomena, such as wind speed or hail.

Is rain in Dubai due to cloud seeding?

In the UAE, cloud seeding is being conducted by the weather authorities to create artificial rain. The project, which began in July 2010 and cost US$11 million, has been successful in creating rain storms in the Dubai and Abu Dhabi deserts.

Who invented cloud seeding?

Modern-day cloud seeding was launched in the lab of noted surface scientist Irving Langmuir at General Electric in 1946. His colleagues Vincent Schaefer and Bernard Vonnegut, brother of author Kurt, discovered that silver iodide could transform supercooled water vapor into ice crystals at temperatures of –10 to –5 °C.

Which chemical is used in artificial rain?

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.

Does Singapore do cloud seeding?

The Republic of Singapore Air Force (RSAF) does practice cloud seeding operations and has cloud seeding equipment [4].

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.

Why does Dubai flood?

Heavy rain triggers flooding in Dubai.

Is cloud seeding expensive?

With our fast growing population, the UAE is under pressure to come up with cost-effective alternatives. Now, desalinating 1 cubic metre of water from the sea costs about $60, whereas the same amount of water extracted through cloud seeding costs just $1.

Who invented artificial rain?

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.

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 long has cloud seeding been around?

1946Cloud seeding as we know it today got its start in 1946 when Dr. Vincent J. Schaefer, working at the General Electric Laboratory in New York, was involved with research to create artificial clouds in a chilled chamber.
