Acoustical Method and Device for Precipitation Enhancement Inside Natural Clouds

摘要

Acoustic method was analyzed to obtain fast droplets coalescence inside nature clouds up to rainy big sizes with gravity sedimentation. Droplets are triggered by sound waves which provide the same high speed for coalescence process near 300 m/s. Optimal acoustic generator is proposed, optimal regimes for cloud droplets have been found at low frequencies of f ～ 100 Hz with low acoustical power. Aadditional acoustic possibilities for rain stimulations provide fast improvement for hot arid weather in local areas on tens-kilometer scales.
