Abstract

In order to further study the mechanism of the Qinghai-Tibetan plateau eastward clouds which trigger the heavy rainfall in Yangtze river basin in summer, the research project group plans to make intensive observation on the cloud eastward movement of the plateau in the summer of 2018-2019 by using the plateau comprehensive observation network to obtain the new data of cloud precipitation physical processes including water vapor, cloud, precipitation particle phase distribution and so on. In this paper, based on precipitation observation data of X-band dual linear polarization radar at Ganzi, Sichuan province during the pre-observation test period from September to October in 2017, the observation data quality and its detection ability are presented. The analysis results indicate that the performance of the radar system is stable during that period. In general, the polarization radar data quality is good, and the corrected radar data can reflect the actual polarization characteristics of precipitation particles, which can lay a foundation for the follow-up of field observation experiment and the study on the parameterization scheme of cloud and precipitation physical process.
