The most common chemicals used for cloud seeding include silver iodide and dry ice (frozen carbon dioxide). The expansion of liquid propane into a gas has also been used and can produce ice crystals at higher temperatures than silver iodide. The use of hygroscopic materials, such as salt, is increasing in popularity because of some promising research results.
Seeding of clouds requires that they contain supercooled liquid water-that is, liquid water colder than zero degrees Celsius. Introduction of a substance such as silver iodide, which has a crystalline structure similar to that of ice, will induce freezing nucleation. Dry ice or propane expansion cools the air to such an extent that ice crystals can nucleate spontaneously from the vapor phase. Unlike seeding with silver iodide, this spontaneous nucleation does not require any existing droplets or particles because it produces extremely high vapor supersaturations near the seeding substance. However, the existing droplets are needed for the ice crystals to grow into large enough particles to precipitate out.
In mid-latitude clouds, the usual seeding strategy has been predicated upon the fact that the equilibrium vapor pressure is lower over ice than over water. When ice particles form in supercooled clouds, this fact allows the ice particles to grow at the expense of liquid droplets. If there is sufficient growth, the particles become heavy enough to fall as snow (or, if melting occurs, rain) from clouds that otherwise would produce no precipitation. This process is known as "static" seeding.
Seeding of warm-season or tropical cumulonimbus (convective) clouds seeks to exploit the latent heat released by freezing. This strategy of "dynamic" seeding assumes that the additional latent heat adds buoyancy, strengthens updrafts, ensures more low-level convergence, and ultimately causes rapid growth of properly selected clouds.
Cloud seeding chemicals may be dispersed by aircraft (as in the second figure) or by dispersion devices located on the ground (generators, as in first figure, or canisters fired from anti-aircraft guns or rockets). For release by aircraft, silver iodide flares are ignited and dispersed as an aircraft flies through the inflow of a cloud. When released by devices on the ground, the fine particles are carried downwind and upwards by air currents after release.
An electronic mechanism was tested in 2010, when infrared laser pulses were directed to the air above Berlin by researchers from the University of Geneva.The experimenters posited that the pulses would encourage atmospheric sulfur dioxide and nitrogen dioxide to form particles that would then act as seeds.

How do you make rain go away?
Unfortunately, it is not possible to make rain go away. Rain is a natural phenomenon that is part of the water cycle and plays a crucial role in the ecosystem. Embracing rainy days and being prepared with appropriate clothing or indoor activities can help make the most of it.
Salt maker is also a rainmaker is its silver salt scattered into clouds?
The phrase "salt maker is also a rainmaker" likely refers to the belief that someone who creates salt from seawater also has the ability to make rain, indicating a connection between the two processes. The idea that silver salt scattered into clouds can induce rain is not grounded in scientific evidence and is considered a myth or folklore. Rain formation is influenced by factors such as atmospheric conditions, temperature, and humidity, rather than the presence of silver salt.
Which material is used to provide condensation nuclei in artificial rainmaking?
Silver iodide or solid carbon dioxide (dry ice) are commonly used materials to provide condensation nuclei in artificial rainmaking. These materials help water vapor in the atmosphere to condense, leading to the formation of rain droplets.
How do we make our soil and lakes safe from acid rain?
To make soil and lakes safe from acid rain, we can reduce emissions of sulfur dioxide and nitrogen oxides that contribute to acid rain by implementing cleaner technologies in industries and transportation. Additionally, we can use methods like liming to neutralize the acidity in soil and lakes affected by acid rain. Regular monitoring of soil and water quality can also help identify areas that need attention.
How do some countries make rain?
Some countries use cloud seeding, where chemicals are dispersed into clouds to encourage rain droplet formation. This process can help increase precipitation in areas experiencing drought conditions. However, the effectiveness of cloud seeding can vary depending on the natural cloud conditions and the amount of available moisture in the atmosphere.
How do rainmaker make rain?
The only known way to make rain is by physically seeding clouds, usually with silver iodide and dry ice. Traditional rainmakers do not actually have the ability to make rain.
How do the royal rainmakers of Thailand make rain?
There is no way to make rain without physically seeding clouds, usually with silver iodide and dry ice. Traditional rainmakers do not actually have the ability to make rain.
Which compounds are sprayed over clouds to cause artificial rain?
Silver iodide or sodium chloride are commonly used compounds to induce artificial rain through cloud seeding. These compounds help to encourage the formation of ice crystals within clouds, leading to precipitation in the form of rain or snow.

What chemicals do people throw in the clouds to make it rain?
Silver iodide or potassium iodide are often used to seed clouds and induce rainfall. These chemicals help to create nuclei around which water droplets can condense and form clouds, which eventually leads to precipitation. Cloud seeding is typically done by aircraft or ground-based generators.
