Key Takeaways
- Delhi’s first artificial rain via cloud seeding could happen on October 29
- Five trials planned in northwest Delhi to combat post-Diwali pollution
- Project involves Delhi government, IIT-Kanpur, IMD, and IITM Pune
- DGCA-approved operations with strict safety protocols
Delhi is preparing for its first-ever artificial rainfall through cloud seeding, with the initial attempt potentially occurring on October 29. Chief Minister Rekha Gupta confirmed the groundbreaking initiative aimed at reducing the city’s severe winter pollution.
A successful trial flight over Burari has already tested the cloud seeding system, deploying silver iodide and sodium chloride into clouds. The project represents a collaborative effort between the Delhi government and IIT-Kanpur, with additional support from the India Meteorological Department and IITM Pune.
Pollution Control Strategy
Authorities have planned five cloud-seeding trials specifically in northwest Delhi to target particulate pollution during the critical post-Diwali smog season. The operations have received necessary approvals from the Directorate General of Civil Aviation and follow strict safety and air traffic protocols.
How Cloud Seeding Works
Artificial rain generation involves releasing substances like silver iodide or sodium chloride into clouds using specially equipped aircraft. These particles serve as nuclei that encourage water droplets to condense, grow, and eventually form raindrops.
The success of artificial rainfall depends on sufficient moisture content in the clouds—typically requiring humidity levels around 50 percent or higher. Aircraft deploy pyrotechnic flares to safely disperse the seeding substances over targeted areas.
This scientific approach represents Delhi’s innovative attempt to wash particulate matter from the atmosphere, offering a potential solution to the city’s persistent winter air quality crisis. The initiative marks a significant step in using advanced technology to address environmental challenges in the national capital region.
