利用贵州省兴义多普勒天气雷达复合体扫基数据资料及自动站雨量资料,在充分考虑了本地地理环境、气候背景的前提下,对贵州省黔西南地区2008～2009年产生的强天气过程进行了降水估测分析。分别采用最小二乘法及A值平均法得到该区域的Ze-I关系,然后对这2种方法的统计结果所做的Ze-I方程进行了对比。选取2010年2次强降水天气过程,用这Ze-I方程分别对其进行降水估测并与实际降水量和误差进行了对比分析。结果表明,Ze-I方程适用性较好,最小二乘法所建立起来的方程比A值平均法实用性好。

Based on Xingyi Doppler weather radar data and precipitation from weather automatic station,considering local geography and climate background,the rainfall during the strong convective weather processes occurred in southwestern Guizhou from 2008 to 2009 were estimated.The relations between effective reflectivity factor（Ze） and rainfall intensity（I） were obtained by using least square method and average A method,then the two kinds of equations about Ze and I was compared.Two strong rainfall processes occurred in 2010 were selected and the rainfall during these two weather processes were estimated by using two equations,and the estimated rainfall was compared with the observed rainfall,in addition the error analysis was made.Results show that the equation established by using least square method is better than that of average A method.
