National Policy on Cloud Seeding
The Minister of State in the Ministry of Planning,
Minister of State in the Ministry of Science and Technology and Minister
of State in the Ministry of Earth Sciences Dr Ashwani Kumar stated in
Rajya sabha that Central Government is aware that Gujarat has
adopted cloud seeding technology to tackle drought in the state;
Replying a question in Rajya Sabha Dr. Kumar said that Gujarat is
testing, in a limited way, on a local scale (5-10Km range) warm cloud
seeding methodology involving burning of candles made up of silver
iodide and burning agents from 5 different locations simultaneously
under typically identified atmospheric conditions (90% humidity, low
wind conditions). The success of this experiment has not been assessed.
As things stand today, artificial rain making techniques cannot be used
for bringing rain clouds to rainfall deficit/drought areas. Such
efforts can only induce potential preexisting clouds, already passing
over a given place, to produce rain only if organized weather
modification intervention becomes successful.
