Characteristics and Applications of Summer Season Raindrop Size Distributions Based on a PARSIVEL2 Disdrometer in the Western Tianshan Mountains (China)

The summer season raindrop size distribution (DSD) characteristics and their important applications, based on a PARSIVEL2 disdrometer installed in Zhaosu over the western Tianshan Mountains, China, 2020–2021 are studied. Our analysis reveals that, for total rainfall different types, DSD follows normalized gamma model, convective has higher concentration than stratiform at all diameters. For rainfall, mean value of mass-weighted diameter (Dm) is lower that DSD, while intercept parameter (log10 Nw) continental according to conventional classification, which characterized by relatively larger Dm log10 Nw values. derived µ–? relation exhibits some differences from those reported eastern, southern, northern China Tibetan Plateau. Furthermore, Z–R relations compared with other regions. Analysis shows empirical Z = 300R1.4 (widely used), strongly overestimates R precipitation Zhaosu. C-band polarimetric radar estimation derived, R(Zh,Zdr) R(Kdp,Zdr) perform best quantitative estimation. Moreover, Dm–Zku Dm–Zka beneficial improvement retrieval algorithms GPM DPR. Lastly, kinetic energy proposed this study can be used better assess erosivity. relationships evaluated provide an opportunity (1) improve both ground-based remote sensing radars (2) enhance estimates erosivity studies
