Cloud Seeding : Delhi Govt
Delhi is grappling with severe air pollution, the concept of cloud seeding has emerged as a potential short-term solution to combat the hazardous air quality.
- Cloud seeding, also known as artificial rain, is a weather modification technique that aims to enhance precipitation by introducing substances into clouds to stimulate rainfall.
- The science behind cloud seeding involves dispersing materials such as silver iodide, potassium iodide, or dry ice into clouds to encourage the formation of rain or snow.
- These particles serve as nuclei for water droplets to form around, potentially leading to increased precipitation.
- The process can be carried out using aircraft, ground-based generators, or even rockets in some cases.
- Cloud seeding is done to increase the radius of the cloud droplets so that they will grow bigger and because of gravity, they will come down as rainfall.
- In the context of air pollution, cloud seeding is seen as a potential method to “wash away” particulate matter and other pollutants from the air.
- The theory is that increased rainfall could help settle dust and other airborne particles, temporarily improving air quality.
- Suitable atmospheric conditions are necessary for the technique to be effective, including the presence of clouds with sufficient moisture.
