摘要
本文对虹桥机场近十年75个低能见度天气过程进行统计分析。研究表明:虹桥机场低能见度集中在11月-次年2月,04-08时出现频率最高;低能见度消散速度快于生成速度;低能见度发生前静风突然增多、气温逐步降低、气压振荡走低,低能见度消散伴随风速增大、气温快速上升、气压升高,而相对湿度与气温呈反相关走势,它们的消散过程比生成过程变化的要快。
In this paper, the meteorological factors are analyzed by using the data of low visibil- ity weather process at Hongqiao airport in recent ten years. The results show that low visibility of Hongqiao airport concentrates in November to February. It occurs at the highest frequency of 04：00- 08：00. The dissipation rate of low visibility is faster than its formation. Before the formation of low visibility, wind calms and the temperature and the air pressure gradually decreases. While the dissipa- tion of low visibility is always accompanied by increasing wind speed, temperature and air pressure. Relative humidity and air temperature are anti-dependent which indicates that the dissipation process is more complicated than its formation.
