What Are The Dangers Of Cloud Seeding?

Can rain stop volcanoes?

Excessive rainfall can and does impact volcanoes.

Having said this hurricanes and other large storms, having a rainfall rate needed to cause water to seep into the lava dome of a volcano are mostly found in the tropics..

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.

Which is the first state in the India to attempt cloud seeding?

Tamil NaduTamil Nadu became the first state in the country to attempt cloud- seeding as early as 1983-1984. Karnataka and Maharashtra followed in 2003 and 2008 respectively when drought situations prevailed.

Is cloud seeding good for volcanic eruption?

(But the amount of rain it would produce and where it would fall over, obviously, there should be an ideal condition where you will cloud seed.) While Solidum agrees that cloud seeding is “good in general”, he also mentioned the possibility of triggering flood and lahar.

How does cloud seeding affect the water cycle?

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.

Is rain good after ashfall?

According to a global network of scientists, the International Volcanic Health Hazard Network, freshly fallen acid particles “can have acid coatings” that may irritate the lungs and eyes. When ashfall is mixed with rain, the acid coating is removed, and may then pollute water sources and damage crops, IVHHN said.

How are artificial clouds made?

Abstract. An artificial cloud in the cloudless atmosphere at a temperature below 0 degrees C was formed by introducing pellets of Dry Ice into air containing more water vapor than would be present at the saturation point with respect to ice.

Where does most of the water that evaporates on earth come from?

Evaporation from the oceans is the primary mechanism supporting the surface-to-atmosphere portion of the water cycle. After all, the large surface area of the oceans (over 70 percent of the Earth’s surface is covered by the oceans) provides the opportunity for large-scale evaporation to occur.

Is cloud seeding harmful to the environment?

Silver iodide, the material used in cloud seeding, is toxic to aquatic life. So precipitation from seeded clouds can harm the environment. In response to these concerns, scientists have tested nontoxic replacements for silver iodide. They have found calcium chloride to be effective.

What chemicals are used in cloud seeding?

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.

Who invented fake rain?

Vincent SchaeferVincent Schaefer, a self-taught chemist who invented cloud seeding and created the first artificially induced snow and rainfall, died Sunday in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr. Schaefer drew worldwide attention with his 1946 experiments for General Electric Co.

Who invented 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.

Does it ever rain in Dubai?

Rainfall in Dubai is infrequent and does not last for a long period. It mostly rains during the winter period between November and March in the form of short downpours and an occasional thunderstorm. On average, rain falls only 25 days a year.

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.

What are the two main things that happen to precipitation?

Precipitation falls to the ground as snow and rain. It eventually evaporates and rises back into the atmosphere as a gas. In clouds, it turns back into liquid or solid water, and it falls to Earth again.

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.

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.

Can we artificially make rain?

Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.

What happens when it rains during ashfall?

Conditions and what to expect Furthermore, rain may accompany the ash and turn the tiny particles into a slurry of slippery mud. Most people also describe an intense quietness, except for thunder that may accompany the ashfall, giving a “deadness” to the normal sounds of life.

How expensive is cloud seeding?

He estimated ground-based cloud seeding costs as little as $4 per acre foot of water produced, while seeding by air is $75 per acre foot.

Does rain come from clouds?

Clouds are made of water droplets. 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.
