不同作业工具人工防雹的对流云回波特征对比分析

Comparative Analysis of Convective Cloud Echo Characteristics of Artificial Hail Suppression of Different Working Tools

为分析不同作业工具开展作业的对流云的雷达回波演变特征,基于新一代天气多普勒天气雷达资料,在分析近年来云南省冰雹发生发展的物理过程的基础上,统计整理滇中地区近几年人工防雹个例资料,对比分析高炮和火箭作业工具的对流云回波演变特征,通过数理统计方法,分析回波强度、45 dBz回波高度、回波顶高等与各指标的对应关系,得到不同防雹工具的作业指标,为人工防雹作业中不同作业器具作业方案的研究提供了一定的思路。

In order to analyze the radar echo evolution characteristics of convective clouds with hail suppression in different working tools, this paper comparatively analyzed the convective cloud echo evolution characteristics of the artillery and rocket tools, through the mathematical statistics method, under the premise of analysis of the occurrence and development of hail in Yunnan Province in recent years based on CINRAD data. The operation index of different hail suppression tools was obtained through analysis of echo intensity, 45 dBz echo height, echo top as their corresponding relationship between higher and various indicators by mathematical statistics. The research provides certain ideas on the operation schemes of different working tools.
