Chinese researchers have found a way to increase rainfall by using low-frequency sound waves. According to Chinese scientists, low-frequency waves directed towards a cloud could increase rainfall and reduce drought in dry areas.

During the research, scientists from Tsinghua University in Beijing directed sounds of about 50 hertz to the clouds. These sounds can barely be heard by humans as they were at 160 decibels.
According to Professor Wang Guangqian, the sound waves excites and vibrates the cloud this then prompts water particles to collide and create droplets, thereby increasing the chances of rainfall.
There were more water droplets in the clouds after they released the low-frequency wave. The sound of the device used in firing the waves was like that of a running jet engine. Wang and his team are optimistic that this new device they developed can bring rainfall to parts of the world suffering from drought.

Chinese scientists say they used sound waves to increase rainfall over the Tibetan plateau by up to 17 per cent.
Powerful, low-frequency sound waves could be used to trigger rainfall in areas that suffer from drought, according to a study by researchers at Tsinghua University in Beijing.
In a weather manipulation experiment conducted on the Tibetan Plateau last year, the researchers, led by Professor Wang Guangqian from the university’s State Key Laboratory of Hydro-science and Engineering, said they recorded increases in rainfall of up to 17 per cent by pointing a giant loudspeaker at the sky.

“The total annual atmospheric water vapour resource in China is about 20 trillion tonnes. [But] only 20 per cent forms natural precipitation that reaches the ground, and the precipitation conversion rate in western regions is even smaller,” said the team led by Professor Wang Guangqian from the university’s State Key Laboratory of Hydro-science and Engineering.
