一次雪后跑道视程(RVR)数值偏低原因分析

自动气象观测系统是专门用于民航机场气象部门进行气象数据的自动采集、计算处理和存储的设备,可以自动连续测量跑道视程、风向、风速、温度、湿度、气压、降水等气象要素。通过青岛流亭机场在一次大雪过后自动气象观测系统测量的跑道视程数值偏低的原因查找和修正过程,希望能够对其他机场遇到雨、雪等特殊天气及数据异常时的自动气象观测系统维护、维修工作提供借鉴。

Analysis of Reasons behind Low Runway Visual Range after a Snowfall

The automatic meteorological observation system is a kind of automatic equipment specially used by meteorological department of civil aviation airport to automatically collect,calculate,process and store meteorological data.It can continuously and automatically measure the runway visual range,wind direction,wind speed,temperature,humidity,air pressure,precipitation and other meteorological elements.This paper focuses on analyzing the reasons for the low runway visual range measured by automatic meteorological observation system after a heavy snow in Liuting Airport of Qingdao.This paper is expected to provide reference for the maintenance and repair work of automatic meteorological observation system when other airports encounter special weather condition such as rain and snow as well as abnormal data.
