# Clouds From the Ground (DD-388)

> Cloud seeding adds particles such as silver iodide or salt to clouds so water vapor condenses or freezes on them, potentially increasing rain or snow. Ground-based generators burn a silver iodide solution and rely on winds to carry the particles into suitable clouds; aircraft are used too. How much precipitation it adds is debated. The footage shows a large vapor plume billowing from a ground test stand; it does not appear to show cloud seeding itself.

### Transcript

Did you know? Cloud seeding from the ground involves releasing particles, such as silver iodide or salt, into the atmosphere from ground-based generators to encourage precipitation. These particles act as cloud condensation or ice nuclei, helping water vapor and clouds condense into droplets or form ice crystals, which then grow heavy enough to fall as rain or snow. Ground-based seeding is typically used when weather conditions, such as favorable wind patterns, allow the particles to be carried into suitable clouds. This method is often deployed in areas experiencing drought or where water resources need to be augmented. NOW YOU KNOW!
