Abstract

This study analyzed the sensitivity of the double-moment normalization of rain drop size distributions (DSDs) to their integration time steps. Six DSD datasets measured at different integration time steps were modeled by the double-moment normalization method. Six couples of reference moments are used for the normalization. Three DSD models (gamma, generalized gamma and lognormal) are used for modeling. Statistical criteria are used to assess the estimation of the moments of the DSDs made by the models. As results, the analysis highlighted the dependence of the shape function parameters on the DSD integration time step. It is also noted that the three DSD models are well adapted to the data used. Nevertheless, the generalized gamma model is recommended because of the independence of the moment estimation errors with respect to the integration time step, which is not the case for the other models.

雨滴大小分布积分时间步长对其双矩归一化的影响——以贝宁北部为例
本文分析了雨滴大小分布的双矩归一化对其积分时间步长的敏感性。采用双矩归一化方法对不同积分时间步长的6个DSD数据集进行建模。采用六对参考矩进行归一化。三种DSD模型(伽玛,广义伽玛和对数正态)用于建模。统计准则用于评估模型对dsd矩的估计。结果表明,形状函数参数对DSD积分时间步长的依赖性较强。还应指出,三个DSD模型很好地适应了所使用的数据。然而,由于矩估计误差相对于积分时间步长是独立的,所以推荐使用广义伽玛模型,而其他模型并非如此。

期刊介绍: Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
