摘要
人工增雨(雪)常用的评估方法为统计检验和物理检验,统计检验需要大量试验样本,且随机化试验在我国难以实现,大量样本无从获得。物理检验目前主要是雷达观测演变状况和飞机直接观测云内微物理参数,由于技术和能力有限,这些方法都难以实现。为了在人工影响天气作业后尽快得出评估结果供政府及环境保护等部门参考,利用雨滴谱记录数据对一次人工增雪作业后的效果进行了评估,发现这些数据在没有常规降雪记录情况下具有一定的参考价值。从评估结果看,人工增雪作业后,降水强度有明显增大的趋势。
The commonly used methods of artificial precipitation are statistical tests and physical examination. The statistical tests method needs a large quantity of samples, which make the randomized experiments difficult to achieve in our country because there is no way to get a large number of samples. The physical examination method is mainly to observe the changing situations by radar and observe the microphysical parameters by aircraft. Due to limited technology and capacity, those methods are hard to achieve. In order to get the assessment results to provide reference for the government and environmental protection authorities after the artificial weather modification, used the raindrop size distribution data to evaluate the effect of the job, it turned out that these data have some reference value in the case of absence of regular snowfall. It was concluded that after the artificial snow operation, the rainfall intensity tends to increase significantly.
