乌鲁木齐机场因天气原因造成航班延误的统计分析
Statistical Analysis of Flight Delays Caused by Weather at Urumqi Airport
摘要:
本文应用2014年1月至2018年11月乌鲁木齐机场例行天气报告和2014年11月至2018年7月的每日航班运行数据,对乌鲁木齐机场重要天气进行分类统计,并对乌鲁木齐机场因天气原因造成的航班延误进行分析,得到了该类延误占延误总量的比例和该类延误的季节性差异和月季差异。结果表明因天气原因造成的航班延误在各类延误类型中所占的比例最多,且具有明显的季节性差异和月季变化,主要发生在冬季,导致延误的天气主要是低云低能见度,其次是降雪。
Abstract:
Using the routine weather reports from January 2014 to November 2018 and the daily flight oper-ation data from November 2014 to July 2018, this paper investigates the statistical characteristics of the high-impact weathers at Urumqi Airport and the contribution of the high-impact weathers to the total flight delays at Urumqi Airport is analyzed. In addition, the seasonal and monthly vari-ations of flight delays induced by the high-impact weathers are studied. The results show that the proportion of flight delays caused by the high-impact weather is the highest among all types of de-lays. This kind of delay shows clear seasonal and monthly variations, which mainly occurs in winter associated with low cloud, low visibility, and snow.
