Artificial rain inducement is know as cloud seeding. There are three methods for cloud seeding: static, dynamic and hygroscopic.

  • Static cloud seeding is done by spreading silver iodide, or another chemical substance like it, into clouds. The moisture in the air condenses around the silver iodide molecules and then falls to the ground in the form of rain.
  • Dynamic cloud seeding is basically a much more complex form of static cloud seeding. Dynamic cloud seeding is divided into eleven complicated steps, and failure to properly complete one of them can result in the ruin of the entire project. Thus, dynamic cloud seeding is generally considered more unstable than static cloud seeding.
  • Hygroscopic cloud seeding involves shooting salt crystals into the lower regions of clouds. The moisture in the clouds condenses on the salt crystals and than falls down to the grown as rain.
