摘　　要：利用宁夏南部山区隆德气象站观测场使用的三种不同型号雨量器同期测得的155组有效降水观测资料,文章对比分析了小时雨量值、每天08:00、20:00观测值、日观测数据差异。结果表明:人工观测雨量器和SL3-1型翻斗式雨量传感器观测的降水量,两者差异较小;DSC3型称重式降水传感器观测的降水量较前两种仪器偏小,并且降水量级越大,误差越大,特别是5mm以上降水的误差明显偏大。分析表明设备的分辨力、响应时间都会引起降水观测误差。By means of 155 groups of effective rainfall observation data from three different types of rain gauge that used in Longde meteorological observation field located in south mountain area of Ningxia,this paper comparatively analyzes the differences of hourly precipitation value,daily observation data at eight o＇clock in the morning and eight o＇clock in the evening.The results show that the differences between precipitation values from artificial rain gauge and SL3-1tilting rainfall sensor are smaller.But the observed results in DSC3 weighing precipitation sensor are less than the first two gauges.In addition,the more precipitation magnitude is,the more errors there are.Especially if precipitation is more than 5mm,its error is higher.The analysis indicates both of resolution and response time of the facility will cause observed precipitation errors.
