Statistical analysis of 2024 experimental acoustic rainfall enhancement,Jimsar County,Xinjiang
摘要
Abstract
Acoustic rainfall enhancement(ARE)technology employs ground-based high-intensity sound sources to accelerating the coalescence of cloud droplets.This technology offers several operational advantages,includ-ing no airspace occupation,flexible operational control,and low operational costs,making it particularly suitable for long-term operations in arid and semi-arid regions.Furthermore,it enables integrated utilization of atmospher-ic and surface water resources through reservoir storage.From May to August 2024,field experiments were con-ducted in the Xidalongkou River Basin,Jimsar County,Changji Hui Autonomous Prefecture,Xinjiang Uygur Au-tonomous Region,China.An operational site was established and observational instruments were deployed to conduct comparative ARE experiments.Using ground-based precipitation observations from 13 valid operational days and 8 valid control days,an impact area identification algorithm was developed using the double-ratio meth-od and Mann-Whitney U test to statistically analyze the spatial extent and effectiveness of ARE.The results are as follows:(1)The acoustic operations altered the localspatial distribution of rainfall,with enhanced rainfall ob-served at the sound-emissionsite and downwind areas,an impact area of 91 km2.(2)The rainfall enhancement ra-tio within the impact area was 58%,using Mann-Whitney U test;P-value=0.008.(3)Duringthe 13 operational days,enhanced rainfall depth of 68.4 mm and enhanced rainfall volume of 6.22×106 m³were observed,the entire experimental period,a total rainfall volume of 8.21×106 m³can be enhanced.This study provides empirical evi-dence and technical reference for implementing Xinjiang water augmentation strategy.However,operational ap-plication of this technology requires further validation at larger spatiotemporal scales and in-depth investigation of cloud microphysical processes.关键词
