| 摘要 | As an emerging meteorological detection tool, X-band dual polarization radar has gradually become an important means of radar quantitative precipitation estimation (QPE) due to its high spatial resolution and sensitivity. In this paper, utilizing the advantages of polarization parameters of dual polarization radar, the QPE product of Guigang X-band radar was optimized, and the optimized algorithm results were compared with the QPE products of surrounding Nanning and Yulin S-band radars. The results showed that the optimized method using polarization parameters of horizontal reflectance factor (ZH) and differential reflectivity (ZDR) had higher consistency between the QPE product of Guigang X-band radar and the measured precipitation of automatic weather stations. In terms of quantitative precipitation estimation, Guigang X-band radar was slightly inferior to Nanning and Yulin S-band radars. |
