How to Monitor Rainfall and Snowfall by Tipping Bucket and Weighting

在水文和气象降水观测中,降雨已实现了自动监测,并且技术成熟,但降雪的自动监测还没有较为可靠的方法。重点剖析影响雨雪量监测精度的多种因素;从多年研究及实践出发,提出一种使用翻斗与称重相结合的监测技术,以期进一步提高雨雪量尤其是降雪量的监测精度。研究表明:翻斗称重式雨雪量监测方法从理论上克服了加热融雪和单纯称重这两种雪量监测方法的不利因素,能够提高观测精度,实现雨雪量一体化自动观测。

The rainfall has been recorded automatically in hydrological and meteorological precipitation observation,and its technology is mature.However,the snowfall automatic monitoring is still far away from achieving a reliable method.The factors affecting the accuracy of rainfall and snowfall monitoring were analyzed.This paper proposed a new monitoring technique combined tipping bucket with weighting based on many years research and practice.The research indicates that the rain and snow monitoring method based on tipping bucket and weighting theoretically overcome the disadvantage factors of snowfall monitoring by heating and weighting.And the method could improve the observation accuracy to realize the unified and automatic observation of rainfall and snowfall.
