Delhi Government Partnered With IIT-Kanpur To Conduct Cloud Seeding:
The Delhi government partnered with IIT-Kanpur to conduct cloud seeding experiments to combat rising post-monsoon air pollution. However, experts from the Ministry of Earth Sciences have cautioned that the absence of rain-bearing clouds during the post-monsoon season makes the timing scientifically unsuitable, casting doubt on the effectiveness of the initiative.Cloud seeding is a weather modification technique aimed at enhancing precipitation (rain or snow) from existing clouds.It involves dispersing substances such as silver iodide, potassium iodide, sodium chloride, or dry ice (solid CO₂) into clouds using aircraft. These particles act as cloud condensation nuclei (CCN) or ice nuclei (IN), mimicking the structure of ice and prompting supercooled water droplets in the clouds to freeze. As these ice crystals grow larger and heavier, they eventually coalesce and fall to the ground as rain or snow. Cloud seeding cannot create clouds, but works only when there are naturally formed clouds with sufficient moisture.
