Cloud and precipitation interference by strong low-frequency sound wave

Acoustic interference of atmosphere has been an attractive research area because of its potential effect on environment, water resources, ecology, agriculture, and other areas. However, it is also a controversial topic because of the difficulty of quantitative assessment and high operating costs. In this study, a novel acoustic interference technology is proposed that uses strong lowfrequency sound waves. There is no chemical pollution or dependence on airborne vehicles, and it can be remotely controlled at low cost. A complete equipment system for acoustic atmospheric interference technology is established, based on which a series of experimental studies on cloud and precipitation response under acoustic action are performed, mainly including the radar echo intensity, cloud microphysical characteristics and the spatial distribution of ground rainfall intensity. The trigger and periodic effect of the acoustic waves on the cloud are proposed to be the key responses of acoustic atmospheric interference. This study is important to further research on atmosphere interference technology based on low frequency strong sound waves.
