摘要：作者探讨了从由高分辨率数值模型以及多参数雷达数据或其他可用测量数据组成的模拟系统中提取微物理信息的优化问题。作为研究这一问题的工具，提出了一种基于粒径分布（PSD）比例归一化通用方法的整体微物理方案。这种方法不依赖于对PSD施加的特定函数形式，并且自然地导致PSD矩之间的幂律关系，从而提供了一种准确且紧凑的PSD表示形式。为了考虑在标准的单矩和双矩微物理方案中被忽略的分布形状/曲率的可能演变，提出了一种基于双矩比例归一化的新的三矩方案。包含在三矩方案中的矩反演方法作为一种结合不同遥感观测的反演算法也可能是有用的……
Abstract The authors address the problem of optimization of the microphysical information extracted from a simulation system composed of high-resolution numerical models and multiparameter radar data or other available measurements. As a tool in the exploration of this question, a bulk microphysical scheme based on the general approach of scaling normalization of particle size distribution (PSD) is proposed. This approach does not rely on a particular functional form imposed on the PSD and naturally leads to power-law relationships between the PSD moments providing an accurate and compact PSD representation. To take into account the possible evolution of the shape/curvature of the distribution, ignored within standard one- and two-moment microphysical schemes, a new three-moment scheme based on the two-moment scaling normalization is proposed. The methodology of the moment retrieval included in the three-moment scheme can also be useful as a retrieval algorithm combining different remote sensing observati...
