Cloud Seeding: A Tool for Enhancing Rainfall and Tackling Air Pollution
Key Points
Cloud Seeding: A Tool for Enhancing Rainfall and Tackling Air Pollution - Delhi's collaboration with IIT-Kanpur aims to combat air pollution through cloud seeding, a technique that enhances precipitation by dispersing substances into clouds. This initiative is significant for UPSC aspirants, particularly for GS Paper 3, which covers environmental issues. Last Updated: 2025-10-27
Key Facts About Cloud Seeding
- Cloud Seeding is a weather modification technique for enhancing precipitation.
- Involves dispersing substances like silver iodide into clouds.
- India's MoES conducted studies showing up to 46% increase in rainfall.
- Used in states like Maharashtra and Karnataka for drought relief.
- China and the UAE extensively use cloud seeding for weather control.
- Applications include enhancing rainfall and reducing air pollution.
- Limitations include lack of rain-bearing clouds during post-monsoon.
- Dependence on Western Disturbances for rainfall in North India.
India's Weather Modification Strategy
Cloud seeding is part of India's broader strategy to address environmental challenges and enhance agricultural productivity. As a tool for managing water resources, it aligns with India's economic goals of ensuring water security and supporting agriculture. Internationally, countries like China and the UAE have set benchmarks in cloud seeding, highlighting its potential in weather modification.
