Recent rainfall in Delhi, Gurugram, Noida, and nearby areas of the National Capital Region (NCR) brought relief from the poor air quality. The showers, occurring amid efforts to explore ‘artificial rain’ as a pollution control measure, were light to moderate in intensity. Air quality improved significantly, with the air quality index (AQI) dropping below 100 in the morning compared to 400+ at night.
The Regional Weather Forecasting Centre predicts more light rain in and around Delhi-NCR, covering areas like Rajiv Chowk, ITO, India Gate, Akshardham, Safdarjung, RK Puram, and Lajpat Nagar on Friday morning.
Various regions, including Noida, Dadri, Greater Noida, Faridabad, Jind, Panipat, and others, are also expected to receive showers.
Delhi’s Environment Minister, Gopal Rai, discussed the possibility of artificial rainfall through cloud seeding with a team from IIT-Kanpur. If the weather remains cloudy, artificial rain might be implemented on November 20-21. The Delhi government, committed to combating air pollution, is willing to bear the entire cost of artificial rain and plans to present this stance before the Supreme Court.
Artificial rain involves dispersing substances like silver iodide, potassium iodide, and dry ice into the air to encourage condensation and precipitation. This method has been used worldwide to address water scarcity or drought conditions. If supported by the central government, Delhi aims to initiate artificial rain by November 20.
