| 【 目的】为加深对降水过程微物理发展演变规律的认识，强化雨滴谱资料在冰雹监测等气象服务中的应用。 【方法】利用金沙县雪、雨、雹 3 种不同天气的雨滴谱数据开展对比分析。【结果】(1) 冰雹过程的粒子速度范围、粒子直径范 围均最广，降雪过程的速度范围最小，降雨过程粒子直径较小但是速度范围较大。(2)3 种类型天气粒子直径分档分布特征变 化波形较为一致；速度分档分布特征变化差异较大，降雨、降雹的过程峰值均出现在 4 . 4 m ·s - 1 左右。(3)降水过程雨滴谱数 据 Z-R 关系拟合与经验公式最为接近。【结论】雨滴谱数据可作为多源探测资料分析的有效补充，且可以为修订本地适用的 Z-R 关系式提供有效支撑。 |

| Abstract: |
| n order to deepen the understanding of the evolution of microphysics in precipitation process and strengthen the application of raindrop spectrum data in meteorological services such as hail monitoring , the comparative analysis was carried out based on the raindrop size distribution data of snow , rain and hail processes in Jinsha County. The results show that : (1) The range of particle velocity and particle diameter is the widest in hail process , while the range of particle velocity is the smallest in snowfall process . In rainfall process , however , the range of particle diameter is smaller but the range of particle velocity is larger. (2) The distribution characteristics of particle diameter in the three types of weather are more consistent. The variation of distribution characteristics of velocity is quite different , and the peak values of rainfall and hail processes both appear around 4 . 4 m ·s - 1 . (3) The fitting effect of Z-R relation in rainfall progress is closest to the empirical formula. The data of raindrop size distribution can be used as an effective supplement to the analysis of multi-source detection data and can provide effective support for the revision of the locally applicable Z-R relation . |
