Delhi Chief Minister Arvind Kejriwal announced on Monday that the state government will explore the use of cloud seeding technology to induce rainfall in the national capital during periods of low precipitation. The idea of using cloud seeding was raised during a meeting between Delhi Chief Minister Arvind Kejriwal and officials from the Confederation of Indian Industry (CII) at the Delhi Secretariat. The meeting was held to discuss a range of topics, including pollution, infrastructure, employment generation, skill development, and environmentally friendly projects.
He stated that cloud seeding technology is already being used in China and Dubai, and on the "same lines we will see its possibility in Delhi, especially during winter months".
Glaciogenic cloud seeding is a method of inducing rainfall by dispersing efficient ice nuclei, such as silver iodide particles or dry ice, into clouds. This causes the water droplets in the cloud to freeze, leading to precipitation. According to experts, the effectiveness of cloud seeding in addressing pollution during winter months is relatively modest.
Cloud seeding involves the deliberate stimulation of rainfall in moisture-laden clouds by dispersing substances like common salt or silver iodide into the upper layers of these clouds, typically accomplished using aircraft-mounted jets.
However, the extent of its efficiency remains uncertain. In an official statement, the Delhi government disclosed that the Indian Institute of Technology (IIT) Kanpur is actively researching cloud seeding technology, though the current progress of their study remains undisclosed.
The Confederation of Indian Industry (CII) has said that it will support the Delhi government's road beautification efforts through its corporate social responsibility (CSR) fund.
