THE CONTEXT: Recently, IITM Pune demonstrated that cloud seeding can produce rainfall.


  • IITM Pune conducted a cloud seeding experiment in Solapur city, which typically receives low rainfall due to its location on the leeward side of the Western Ghats.
  • The experiment resulted in an 18% relative enhancement in rainfall, equivalent to approximately 8.67mm more rainfall over a two-hour period.
  • The experiment, called Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX phase-4), used hygroscopic seeding in convective clouds and involved two aircraft for cloud parameter study and seeding.
  • A total of 276 convective clouds were selected, with 150 seeded and 122 left unseeded.
  • Seeded clouds produced more rainfall than unseeded ones, indicating the effectiveness of cloud seeding under suitable conditions.
  • Calcium chloride flares were used for cloud seeding, targeting the base of warm convective clouds during their growing stage.
  • Cloud seeding alone cannot mitigate droughts but can increase rainfall by 18%, partially addressing water requirements.
  • The approximate cost of producing water through cloud seeding was 18 paisa per liter, which could decrease by over 50% if indigenous seeding aircraft were used.
  • The study aims to provide protocols and technical guidance for cloud seeding in India, including the identification of target locations, suitable clouds for seeding, and effective strategies to enhance rainfall.
  • Not all cumulus clouds produce rainfall when seeded, and the actual increase in rainfall was 18% over a 100 sq.km area.


  • Cloud seeding is a weather modification technique that aims to change the amount or type of precipitation that falls from clouds.
  • It does so by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud.
  • Its effectiveness is debated; some studies have suggested that it is “difficult to show clearly that cloud seeding has a very large effect.”
  • The usual objective is to increase precipitation (rain or snow), either for its own sake or to prevent precipitation from occurring in days afterward.


  • Static seeding:
    • This involves introducing condensation nuclei into clouds that are already producing precipitation.
    • The condensation nuclei help water droplets to grow larger, which increases the likelihood of precipitation falling.
  • Dynamic seeding:
    • This involves introducing ice nuclei into supercooled clouds.
    • Supercooled clouds are clouds that contain water droplets that are below freezing temperature but have not yet frozen.
    • The ice nuclei provide a surface for the water droplets to freeze on, which initiates the precipitation process.


  • Cloud seeding can be done from the ground or from the air.
  • Ground-based cloud seeding typically involves using generators to release silver iodide particles into the air.
  • Air-based cloud seeding typically involves using aircraft to drop flares or generators into clouds.
  • Cloud seeding is used in a variety of countries around the world, including the United States, China, Russia, and Australia.
  • It is used for a variety of purposes, including:
    • Increasing precipitation in areas that are experiencing drought
    • Reducing the risk of hail damage
    • Suppressing fog
    • Increasing snowpack in mountain areas
