冰雹谱分布及Z_e-E关系的初步分析

PRELIMINARY ANALYSIS OF THE HAILSTONE SPECTRA DISTRIBUTION AND THE RELATIONS BETWEEN Z e AND

文中分析了大量的地面雹谱资料，给出了雹谱的平均特征及其三种类型。计算了冰雹落地动能通量，并建立了Ｚｅ－Ｅ关系，其相关系数大于０．９６，显著性水平小于０．０１。

A large number data of ground hailstone spectra are analysed. The average characteristics of hailstone spectra and their three types have been obtained.After computing the kinetic energy flux of hailfalls,the Z e E relations are esta blished,and the correlation conefficient is more than 0.96,the significance level is less than 0.01.This work makes a firm basis to evaluate the effects of artificial hail suppression by means of hailpads and radar.
