Popis: To promote the understanding of precipitation microphysical characteristics and differences in the central and eastern Qinghai-Xizang (Tibetan) Plateau and the Sichuan Basin, disdrometer measurements collected at Naqu, Yushu, Linzhi, Batang, Luding, and Chengdu from July to August 2019 and 2020 are utilized to comprehensively investigate the characteristics and differences of raindrop size distributions (RSDs) among the six different areas.Meanwhile, local empirical relations between the Gamma shape parameter and slope parameter and between the reflectivity factor and rain rate are proposed and compared.The results show that RSDs in the basin and adjacent areas (Chengdu and Luding) are generally wider and have higher number concentrations of medium-to-large raindrops (diameter ≥1.0 mm) than those in the plateau areas (Naqu, Yushu, Linzhi, and Batang) due to the contribution of more strong convective precipitation.In contrast, RSDs in the plateau areas are narrower and possess higher number concentrations of small raindrops (diameter
