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.
