摘要
利用2012年11月至2013年3月大连国家基本气象站称重式和人工式观测降水量的2份数据,通过不同级别的差值对比,分析两者之间的差异。结果表明,在降水量≥10 mm时,平均差值百分率为3.15%;在降水量<10 mm时,平均差值为-0.3 mm,总体差值较小。并就分析结果找出差异产生原因。
Based on the Dalian national basic meteorological station precipitation data from Nov.2012 to Mar.2013 ,the difference between the weighing precipitation sensor and artifical through different levels was analyzed.The results showed that when the precipitation was lower than 10ram, the average rate of difference was 3.15%.When the precipitation was higher than 10 mm ,the average difference was -0.3 mm.The total precipitation of difference was small.The causes of the difference were found from the results.
