中文摘要: 本文根据1987年6月29日河北满城县两次降雹过程的观测资料,对降雹的动能作了初步分析。结果表明,成灾地区的冰雹动能、冰雹质量以及冰雹动能通量与质量通量,均明显大于未成灾地区。雹谱呈负指数型分布。成灾地区与未成灾地区的雹谱分布分别为N_成=0.0737c~(-0.2165D)和N_未=0.0134e~(0.2316D)。

Abstract:According to the observed data of two hailfall processes occured in the Mancheng county of Hebei Province during June 29, 1987, kinetic energy of hail-fall to the ground is preliminarily analysed in this paper.It is found that the, kinetic energy density (ET), the flux of kinetic energy (E), the mass .of hail (Mr) and the flux of mass (M) observed in the damaged areas are explicitly much higher than those of non-damaged areas.
