Artificial Rains and Cloud seeding
Posted on : 18 Jan 2020Views: 322
- For the uninitiated, cloud seeding or weather modification is an artificial way to induce moisture in the clouds so as to cause rainfall. In this process, either silver iodide or dry ice is dumped onto the clouds by using an aircraft or an artillery gun which leads to a rain shower.
- According to The Times of India, the cloud-seeding technology currently available in India can only induce potential pre-existing clouds, hence the delay in launching operations. The idea is to use the artificial rain to clear the toxic air in the capital and provide Delhiites with a much-needed respite.
- “The clouds required for cloud seeding are of a typical type. They are called convective clouds and they grow vertically. Only these can be seeded, not the other type, which are called stratified and grow horizontally,” explains J R Kulkarni, a retired scientist from the Indian Institute of Tropical Meteorology, Pune, an autonomous institute of the Union Ministry of Earth Sciences.
