Artificial Rain: Huge success in artificial rain experiments by IITM scientists in Solapur, record 46 percent additional rain
Pune, July 31, 2023: The Indian Institute of Tropical Meteorology (IITM) has achieved a significant scientific breakthrough. The weather scientists successfully conducted artificial rain experiments in Solapur district, an achievement endorsed by the Union Ministry of Earth Sciences in New Delhi. The experiments revealed that spraying salt on certain types of clouds can lead to increased rainfall.
The experiments were part of the fourth phase of the CAIPEEX project, launched by IITM in 2009. The project’s first-ever artificial rain experiment took place in Solapur district in 2018 and 2019, employing two airplanes imported from the United States. One airplane sprayed salt on the clouds, while the second recorded the process.
To ensure accurate data collection, 130 rain gauges were strategically placed across Solapur district. The team meticulously followed the World Meteorological Organization’s (WMO) guidelines, using radar, numerical models, and random sampling. The results of the experiment were impressive. Clouds with a certain water percentage and moving upwards experienced a 46% increase in rainfall according to 43 rain gauge readings.
These successful experiments resulted in an estimated 86.7 crore liters of rainwater falling to the ground after each salt-spraying session. Dr. R Krishnan, the Director of IITM, highlighted the significance of this accomplishment. He explained that artificial rain could offer a solution to drought-stricken areas and protect crops.
The study saw 103 flights conducted to analyze 267 clouds during the monsoon period. The results will soon be published in an international journal, furthering our understanding of cloud science and the potential of artificial rain. This landmark breakthrough offers new strategies to tackle water scarcity and promote sustainable agricultural practices in India’s rain-shadow regions.
During the 17th Foundation Day of #MoES, Hon’ble Union Minister, #MoES, Shri @KirenRijiju, unveiled a comprehensive report on the project. This report highlights the viability of cloud seeding as a strategy to enhance rainfall, mitigate drought conditions, and foster sustainable water management practices. It will soon be available for free download on the IITM website.
