Statistic evaluation of low-frequency acoustic wave impact on rainfall stimulation

For securing more water resources, traditional solutions including seawater desalination are limited due to high cost and restricted operating conditions. Thus, acoustic stimulation of rainfall is a potential alternative method its low convenient operation. Low-frequency fields can be used stimulate through evoking wavy motion air particles in clouds which will significantly enhance the process collision coalescence cloud droplets lead their volume increase. Nevertheless, there still lack rational methods evaluate effect enhancement field experiments. To this end, study, nearly two-month experiments with 39 trials were carried out by our research team Tibetan Plateau. Statistical analysis was applied wave on precipitation stimulation. The results average intensity distribution using ordinary least square disclose that interference has considerable enhancement. Such increases along increase duration index potential. events than two hours, improved 72% at experiment site. phenomena consistent fact larger contain beneficial coagulation process.
