摘要

采用 T 矩阵法,通过建立降水粒子雷达探测模型,模拟不同相态单个粒子以及粒子群在入射波的波长、入射仰角,降水粒子类型、大小、形状、粒子谱分布以及下落过程中粒子的取向等不同条件下,雷达反射率因子Z、差分反射率因子ZDR、比差分相移KDP和零延迟相关系数CC等偏振参量特征,探讨利用多波长偏振雷达联合观测手段识别降水类型的方法,研究表明可用冰雹指数ZHH,S-ZHH,X、各偏振参量的取值范围及其在不同波长下的对比差异来识别降水粒子类型,为提高雷达对强对流天气下降水类型的识别能力,反演强对流系统降水相态的三维精细结构提供了有效的方法。

Abstract

Radar detection model of hydrometeors has been established to derive reflectivity (Z), differential Reflectivity (ZDR), specific differential phase (KDP) and correlation coefficient (CC) of single particle or particle groups under different conditions, such as incident wavelength, incident angle, type, size, shape, size distribution and canting angle, etc.via T -matrix method.The method of hydrometeor classification using multi-wavelength dual linear polarization Doppler radar has been discussed.Results show that hail index (ZHH, S-ZHH, X), the scope of the polarization parameters and comparison under different wavelength are available to classify phase of hydrometeors.An effective method for improving the ability to classify the hydrometeors and retrieve 3d fine structure of hydrometeors in severe convective weather by radar was provided.
