摘要/Abstract

摘要： 对激光雨滴谱仪监测的降水粒子粒径、末速度、粒子数等信息进行分析，得到降水粒子的粒径-末速度函数和雨滴谱等关系函数。通过计算得到的降水强度与气象数据对比，得到误差函数；根据误差函数建立降水量反演算法，对降水强度进行修正得到修正后降水强度和降水量，修正后降水量误差减少了10%以上，最后给出降水类型的判断方法。

Abstract: It is obtained the relation functions between particle diameter, terminal velocity and drop size distribution based on the data of particle diameter, terminal velocity and particle number detected by laser raindrop monitor. The rainfall intensity is calculated and compared with meteorological data to build error functions. According to measurement error, a precipitation inversion algorithm is developed to calibrate rainfall intensity and amount of precipitation, resulting in reducing 10% error of corrected precipitation amount. At last, precipitation type is distinguished by calculated relative data.

Key words: laser raindrop monitor, drop size distribution, rainfall intensity, precipitation inversion, curve
