How Long Does It Take For Cloud Seeding To Work?

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 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 harmful to humans?

Exposure to high levels of silver over a long period of time can result a gray or blue-gray discoloration of the skin and other tissues known as argyria. While this condition is permanent, it is thought to only be a cosmetic problem that is not otherwise harmful to health (ATSDR, 1990; ATSDR, 1999).

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.

What is the purpose of cloud seeding?

Cloud seeding is the process where substances like dry ice and silver iodide are put into clouds in an attempt to make precipitation fall. Cloud seeding has also been used to dissipate fog and weaken some storms.

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.

How much does cloud seeding cost?

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.

Does the US use cloud seeding?

Today California, Idaho, Nevada, Utah and Wyoming have winter cloud seeding programs, and Texas and North Dakota have summer programs, which aim to increase rain and decrease hail. Cloud seeding machines are nothing like the “snow guns” used to blast water over ski slopes.

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 is cloud seeding done in UAE?

The UAE has been carrying out cloud seeding operations for more than a decade. It involves flying an aircraft to a cloud that has little rain droplets already present. The aircraft shoots salt flares into the cloud to enhance rainfall. “Clouds have two air masses – one is up draft and one is down draft.

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.

What is the importance of cloud seeding?

1.3 Cloud Seeding Cloud seeding involves the addition of aerosol, such as silver iodide aerosol, that modifies the phase and size distribution of hydrometeors. The goal of cloud seeding is to alter the natural development of the cloud to enhance precipitation, suppress hail, dissipate fog, or reduce lightning.
