中文摘要: 利用VisualFortran和VisualBasic编程语言及有关算法,研发了多普勒雷达定量测量武夷山九曲溪降水软件系统,利用2002—2004年建阳CINRAD雷达28个过程的回波强度资料和福建省中北部27个地面雨量站与武夷山九曲溪10个自动雨量站的降水资料,通过“最优化处理法”和“相关性检验”等算法确定了三个不同区域三种不同降水类型的9组最优Ab值。利用所得的最优Ab值与最优混合扫描的回波强度资料作为输入,其生成的三种降水产品,在运用雷达定量估测降水方面,比建阳CINRAD雷达的PUP降水产品效果更加明显。
Abstract: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.
