To address the air pollution, the Indian Institute of Technology (IIT) Kanpur has proposed “artificial rain” through cloud seeding to reduce pollution levels in the national capital.
Understanding Cloud Seeding: The Art of Artificial Rain for Weather Modification
Artificial rain: Also known as cloud seeding, it is a weather modification technique used to encourage precipitation by introducing chemicals like silver iodide, potassium iodide, and dry ice into the sky using airplanes and helicopters.
Condensation nuclei: These particles serve as nuclei around which water droplets can form leading to the development of raindrops.
It usually takes about half an hour for this method to make it rain.
Objective: It serves various purposes, including reducing the impact of droughts, preventing forest fires, increasing precipitation, and enhancing air quality.
Exploring Cloud Seeding Techniques: Method of Artificial Rain
Hygroscopic cloud seeding: It aims to accelerate the coalescence of droplets in clouds, resulting in the formation of larger droplets that lead to precipitation.
In this method, salt particles are dispersed at the cloud’s base.
Glaciogenic cloud seeding: It focuses on inducing ice production in supercooled clouds, leading to precipitation.
It involves dispersing efficient ice nuclei, such as silver iodide particles or dry ice, into the cloud, which triggers heterogeneous ice nucleation.
Unlocking Water Resources: The Role of Cloud Seeding in Snowpack Enhancement
Cloud seeding is used for enhancing winter snowfall and increasing mountain snowpack, supplementing the natural water supply available to communities of the surrounding area.
