A Comparative Analysis of Rainfall Accuracy by Using Dual Linear Polarization Radar and the Conventional Weather Radar
|
Abstract:
In this paper,by using the large amounts of raindrop size distribution data of various type rainfall,the relation between rainfall measurements of two kinds of radar and drop size distribution has been analysed.By simulation calculations of the formula of R/ZH-ZDR dual linear polarization radar and Z-R the cenventional weather radar, we have compared their measuring accuracy of rainfall rate.The results show that the differential reflectivity ZDR is sensitive to variation of raindrop size distribution.This is useful to improve the accuracy of rainfall measurements by radar.
