Artificial nucleations refer to the deliberate creation of small particles to enable the formation of clouds or precipitation. Synonyms for this term include cloud seeding, precipitation enhancement, and weather modification. Cloud seeding involves dispersing materials like silver iodide or dry ice into clouds to generate precipitation. Precipitation enhancement involves using electrical fields to increase rainfall. Weather modification is a broad term that includes various techniques such as cloud seeding and hail suppression. Other synonyms for artificial nucleations include rainmaking, cloud brightening, and atmospheric seeding. These techniques have been used in many countries to combat drought and water scarcity, but their efficacy and environmental impact are still under investigation.
