Based on the visual fortran and visual basic programming language and the related algorithm, precipitation software system of the Doppler radar quantitative measurement to Jiuquxi,Mt. Wuyi is developed with the 28 processes echo data of Jianyang CINRAD radar from 2002 to 2004, and the precipitation data of the 27 surface meteorological stations in the mid-north Fujian, and the 10 automatic rainfall stations data of Jiuquxi in the Mt. Wuyi. The 9 groups optimal A and b value of three kind of different precipitation types in three different regions are determined. The effect of the three kinds of precipitation products in precipitation quantitative measurement is more obvious than that of the PUP of Jianyang CINRAD radar.
