摘要
对蒸发量的观测是每个气象观测站每天20:00必须观测的项目,由于人为的因素容易造成蒸发量的测量误差甚至缺测,从而对观测站的整体观测质量造成较大的影响。本文介绍了目前台站普遍使用的E-601B型蒸发器的构造与观测原理,分析了造成该仪器观测误差和缺测的主要原因,重点讲述了E-601B型蒸发器的观测要点。
For each observation station,it must observe evaporation at 20 o clock in a day.Because of man-made factors easily lead to errors and missing measurement,it causes great impact on the overall observing quality.This paper introduces the structure and observation principle of E-601B evaporation apparatus,which commonly used in current station.The main reason that caused measuring errors and missing measurement are analysed.The observation points of E-601B evaporation apparatus are emphatically introduced.
