  • Cloud seeding, a form of weather modification, attempts to change the amount or type of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud.

Chemicals Used for Cloud Seeding

Cloud seeding or 'artificial rainmaking' involves the introduction of certain chemicals into clouds to stimulate precipitation. The most commonly used chemicals for cloud seeding are:

Silver Iodide
Silver iodide is one of the most widely used substances for cloud seeding. It has a similar crystal structure to ice, making it effective in promoting the formation of ice crystals in clouds. These ice crystals then grow and eventually fall as precipitation.

Potassium Iodide
Potassium iodide is another chemical that is sometimes used for cloud seeding. It works in a similar way to silver iodide by promoting the formation of ice crystals in clouds, leading to precipitation.

Dry Ice or Frozen Carbon Dioxide
Dry ice, which is solid carbon dioxide, can also be used for cloud seeding. When dry ice is released into a cloud, it cools the air and causes water vapor to condense around it, forming ice crystals that can grow and fall as precipitation.

All the Above
In some cloud seeding operations, a combination of silver iodide, potassium iodide, and dry ice may be used to enhance the effectiveness of the process. Each of these chemicals has its own unique properties that contribute to the stimulation of precipitation.

In conclusion, all of the above-mentioned chemicals are commonly used for cloud seeding or artificial rainmaking, with silver iodide being the most prevalent choice due to its effectiveness in promoting ice crystal formation in clouds.
