Cloud seeding creates artificial rain

  • The Uttarakhand administration was under examination by the Supreme Court following forest fires that cost lives in the state.
  • The justices emphasised the ineffectiveness of depending entirely on cloud-seeding or rain gods to handle the situation.

About Cloud Seeding

  • Cloud seeding is a weather manipulation method that involves releasing compounds into clouds to increase rainfall or snowfall.
  • It is used to reduce hail, disperse fog, and induce or avoid precipitation on future days.
  • Silver iodide, potassium iodide, dry ice, and hygroscopic items like table salt are all dispersed into the environment.

Techniques include:

  1. Static seeding increases ice particle production in supercooled clouds, whereas 
  2. Dynamic seeding boosts convective cloud growth by releasing latent heat.
  • Dispersion techniques vary from aircraft and ground-based generators to newer options such as drones that emit electric charges or infrared laser pulses.

Limitations: Impact on the Environment and Health.

  • Concerns remain about the possible buildup of seeding agents in delicate ecosystems, despite extensive studies revealing little consequences.
  • The chemicals utilised, such as silver iodide, may possibly harm the environment and create health problems including iodine poisoning in high amounts.
