Cloud seeding

From Wikipedia, the free encyclopedia
Cloud seeding can be done by ground generators, plane, or rocket
This image explaining cloud seeding shows the chemical either silver iodide or dry ice being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation to the introduced chemicals.[1]
Cloud seeding, a form of weather modification, is the attempt 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. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports.
