Weather Modification - Methods Of Cloud Seeding

Methods of cloud seeding

Any technique of cloud seeding depends on the release of millions of tiny particles of dry ice or silver iodide into a cloud. One way of accomplishing that goal is to ignite solid silver iodide in burners on the ground. The smoke thus formed consists of many tiny particles of the compound which are then carried upward into a cloud.

A more efficient way of seeding a cloud is to drop the seeding agent from an airplane onto the top of the cloud. If silver iodide is used, it can be released from flares attached to the wing tips of the aircraft. If dry ice is used, it is first pulverized into a fine powder and then sprayed onto the cloud.
