摘要
应用测雹板布网， 选用雹块大小， 密度以及与其有关的冰雹动能、动能通量、冰雹质量、质量通量等物理量参数作为评估防雹效果的统计量。通过计算， 对作业区与对比区分别进行统计分析， 确定防雹作业效果。
A hail pad network was installed Using physical parameters, such as the size, intensity, kinetic energy, kinetic energy flux, mass and mass flux of hailstone as the statistical parameters for estimate of hail suppression effect, the target and control areas are analyzed statistically so as to estimate the hail suppression effect
