    Effect Evaluation of Acoustic Rain Enhancement Operations of Stratus-Cumulus Mixed Clouds in the Leizhou Peninsula

    • 摘要: 近年来,声波作业作为人工增雨的一种新技术开始受到广泛关注.基于雷州半岛试验区2023年6~8月的声波增雨试验,使用双比分析和区域回归分析方法对增雨结果进行了统计检验,并选取2023年6月15日一次积层混合云声波增雨个例进行了详细分析,旨在为声波增雨在理论和实践上的可行性提供证据.研究结果表明:(1)双比分析和区域回归分析得到的相对增雨率分别为16.54%(p<0.05)、39.76%(t=1.960>t0.05=1.699,p<0.05);(2)声波设备开启后,作业点下游降雨明显增强;(3)物理检验结果表明,受声波影响,作业单元的各雷达探测物理量相较于对比单元均出现正的偏离,声波干预延长了作业单元的成熟阶段;(4)声波影响后,作业单元和对比单元反射率因子的时空演变趋势产生了明显差异.

       

      Abstract: In recent years,acoustics operation began to receive widespread attention as a new technique of artificial precipitation enhancement.Based on the acoustic precipitation enhancement experiment in the Leizhou Peninsula experiment area from June to August 2023,this study conducted statistical tests on the precipitation enhancement results using double ratio analysis and regional regression analysis methods.It is selected for detailed analysis for a case of acoustic precipitation enhancement on June 15,2023,aiming to provide evidence for the feasibility of acoustic precipitation enhancement in theory and practice.The results show that:(1) The relative precipitation enhancement rates obtained from double ratio analysis and regional regression analysis are 16.54% (p<0.05) and 39.76% (t=1.960>t0.05=1.699,p<0.05),respectively.(2) After the acoustic equipment is turned on,the rainfall downstream of the operation site increases significantly.(3) Physical inspection results show that,under the influence of acoustic wave,various radar detection parameters of the target unit have positive deviations compared with the control unit,and the acoustic intervention prolongs the maturity stage of the target unit.(4) After the acoustic influence,there are significant differences in the temporal and spatial evolution trends of reflectivity factors between the target unit and the control unit.
