Artificial Rain Experiment Takes Flight Over the Capital
NEW DELHI: In a pioneering move to combat worsening air pollution, Delhi has carried out its first-ever cloud-seeding trial across multiple areas, including Burari, Karol Bagh, Bhojpur, Mayur Vihar, and Sadakpur. Officials confirmed that the aircraft responsible for the operation took off from Kanpur before performing the seeding exercise over the national capital.
Details of the Cloud-Seeding Operation
During the trial, clouds over Delhi showed humidity levels ranging between 15% and 20%, creating partial conditions for artificial rainfall. Weather experts suggested that the city could witness rainfall between 5 and 6 PM, depending on the stability of the moisture content. This trial forms a key part of the Delhi government’s wider initiative to mitigate air pollution during the winter months, when smog levels are at their worst.
The Science Behind Cloud Seeding
Cloud seeding is a sophisticated weather modification process that involves dispersing substances like silver iodide (AgI) or sodium chloride into clouds. These compounds serve as nuclei, encouraging moisture to condense into ice crystals, which then combine to form raindrops. The artificial rain produced through this technique helps wash away particulate matter and airborne pollutants, significantly improving air quality. However, successful cloud seeding depends heavily on adequate moisture levels within the clouds—typically around 50%.
Previous Test Flight and Observations
A week earlier, the Delhi government conducted a test flight over Burari to assess the feasibility of cloud seeding. During the experiment, small quantities of silver iodide and sodium chloride were released into the atmosphere. Unfortunately, due to insufficient moisture—less than 20%—rainfall could not be induced at that time. Despite the setback, scientists noted valuable atmospheric data that will support future trials.
CM Rekha Gupta’s Vision for a Cleaner Delhi
Delhi Chief Minister Rekha Gupta expressed optimism about the initiative, calling cloud seeding a “necessity” for the capital’s environmental recovery. Speaking to ANI, she stated, “Cloud seeding is a necessity for Delhi and is the first experiment of its kind. We want to see if it can help us control this serious environmental problem.” She further added, “The blessings of the people of Delhi are with the government, and we believe this will be a successful experiment, paving the way for long-term solutions to pollution.”
A Step Toward Sustainable Air Quality Improvement
This landmark experiment positions Delhi among the few cities in India exploring innovative weather-based solutions for pollution control. If successful, cloud seeding could become a vital part of the city’s strategy to counteract the harmful effects of winter smog, improving not just visibility but also public health and urban livability.
