摘要: 为对海南旱季空中云水资源进行有效利用和开发,增大地面降雨量,缓解旱情,通过科学的效果检验验证和分析研究,找出针对海南典型云系的统计检验和物理检验最佳结合的非随机化效果检验方法。通过相似离度判别法用软件自动选取对比云进行效果评估,具体分析了海南省西部农业抗旱火箭增雨作业每个点对流单体的催化效果,对于无对流单体的区域采用非随机化区域对比分析方法评估。二者结果对比发现,在回波顶高方面,对流单体的催化统计效果更好,在液态水含量增大方面,区域对比的催化统计效果显著。其雷达回波各参量之差曲线图,可以通过斜率的变化来清楚的判定目标云的增长趋势,也可判定对比云的消亡时间。从整体而言,虽然二者的分析方法和分析对象不同,但其可以互相补充,互相论证,极大的提高了海南本地化增雨效果的准确性。

Abstract: In order to use and develop the cloud water resources in dry season in Hainan Province effectively, and increase the surface rainfall to alleviate the drought, aiming at Hainan typical cloud, the author studied the nonrandomized effect testing method based on the optimum combination of statistical test and physical test. Through analog deviation discrimination method, the author selected the compared cloud for impact assessment from the software automatically, analyzed the catalytic effect of every rocket convective cells of the western part of Hainan and evaluated the non- convective cells by the method of non- randomized regional comparative analysis. The results showed that, in the echo top aspect, the catalytic effect of convective cells was better, in terms of the increase of liquid water content, the catalytic effect of regional comparative clouds was obvious. Through the curve of radar echo difference of each parameter, the growth trend of target cloud could be clearly showed by the slope, as well as the demise time of compared cloud. As a whole, although the analysis methods and objects were different, it could complement and demonstrate each other, which greatly improved the accuracy of Hainan localized rainfall enhancement effect.
