Study on Z-I Relationship of Rainstorm in Zunyi Region of Guizhou Province

LUO Xiao-song et al(Meteorological Bureau of Zunyi City,Zunyi,Guizhou 563002)  
According to the echo intensity scan data per 6 min and 9 ground stations relevant rain intensity data of 120 km scan range supplied by the new weather radar of Zunyi during the 32 times rainstorm in 2007,the study used the least square method to fit the data and set up the Z-I relationship suited for Zunyi during the rainstorm process.11 times rainstorm in 2008 were effectively tested and the error analysis made from different aspects.The result showed that the Z-I relationship based on the intensity area was more suitable and accurate for Zunyi region than the implicated WSR88D.The new Z-I relationship can provide the better criterion for the quantitative precipitation estimation of the rainstorm in the future,which can play an important role in rainstorm disaster warning.
