1. CLOUD SEEDING
TAG: GS 1: GEOGRAPHY
THE CONTEXT: Recently, IITM Pune demonstrated that cloud seeding can produce rainfall.
HIGHLIGHTS OF THE STUDY:
- 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.
WHAT IS CLOUD SEEDING?
- 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.
TYPES OF CLOUD SEEDING:
- 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.
METHODS OF EXECUTION:
- 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
