Laser-assisted technique can control rainfall and reduce flooding during the monsoon. This was discovered in a field experiment conducted by scientists at the University of Geneva, Switzerland.
The scientists claim to have found a technique to control the weather using laser beams. If that happens successfully, they would be able to determine when it does or doesn't rain, as reported by a Web site.
According to a study published in Nature Communication journal, scientists have found a method to control rainfall using laser-assisted water condensation technique. So far, the molecules formed using a high laser beam were too light to fall as rain, but scientists are working on controlling the size of the droplets.
The field experiment conducted under certain atmospheric conditions shows that the laser filaments can induce water condensation and fast droplet growth up to several μm in diameter in the atmosphere as soon as the relative humidity exceeds 70 per cent.
They say that it could be a potential technique to reduce rains and flooding during the monsoon, in the future. However, the scientists aren't sure of how and where this technique can be used due to certain limitations attached to it. They say it works only in humid air.
However, physicists doubt the efficiency of laser-assisted water condensation above the already existing rain-induction techniques like Cloud seeding that includes silver iodide and dry ice (frozen carbon dioxide) to change the amount or type of precipitation that falls from clouds.
