How Cloud Seeding Can Increase Rain and Snowfall
CNBC・9 minutes read
Cloud seeding involves injecting silver iodide into storm clouds to increase precipitation, with evidence confirming its effectiveness in boosting snowpack and water supply. While beneficial for water management, it is viewed as a long-term strategy rather than a quick solution for droughts.
Insights
- Cloud seeding, a technique involving the introduction of silver iodide into storm clouds to induce precipitation, has been proven effective in increasing snowpack and water supply, particularly in mountainous regions.
- Despite its success in enhancing water resources, cloud seeding is highlighted as a sustainable, long-term approach to water management rather than a rapid solution for drought conditions, showcasing its value as a strategic tool for addressing water scarcity.
