Delhi's Cloud Seeding Trials for Artificial Rain Face Challenges Amid Weather Constraints
Delhi's BJP government, supported by IIT Kanpur, is attempting cloud seeding to induce artificial rain and reduce pollution. Initial trials failed due to low moisture levels, though some improvement in air quality was observed. The success of future trials depends on atmospheric conditions, with more experiments planned. Critics remain skeptical about the effectiveness of cloud seeding in significantly addressing Delhi's pollution crisis.
Delhi's BJP government launched cloud seeding trials to artificially induce rain and combat pollution, collaborating with IIT Kanpur, the technical lead on the project. Despite two attempts costing around ₹1.28 crore, no rainfall was triggered due to insufficient moisture levels (around 10-20%), though particulate pollution saw a 6 to 10 percent reduction. The environment minister stated that further attempts may happen if moisture increases after 4 pm, using a single-propeller aircraft to disperse silver iodide flares over clouds. IIT Kanpur emphasized that the technique's success depends heavily on atmospheric moisture, aiming to collect data on rain probability at different moisture thresholds. The project, initially proposed by the previous AAP government but stalled over permissions and weather, now has a ₹3.21 crore budget for five trials under BJP leadership. Critics, including experts from IIT Delhi and AAP leaders, questioned the efficacy and timing of these trials, labeling them as limited in potential impact due to the rarity of rain-bearing clouds in high pollution periods. Cloud seeding remains scientifically contentious globally, with limited proven results outside specific high-altitude applications. Overall, while the initiative delivers some air quality benefits, it is seen as insufficient to address Delhi's persistent pollution challenges comprehensively.
