昆明长水机场气候特征分析
Analysis of the Climatic Characteristics at Kunming Changshui Airport
中文摘要：
利用昆明市1951—2010年逐日气象数据，采用回归分析法和Mann-Kendall突变分析法进行分析和检验，确定了昆明市极端降水和极端温度天气事件。在此基础上，对昆明长水机场极端天气背景下大雾天气航班安全运行开展研究，并在对比昆明长水机场与原巫家坝机场大雾特点的基础上，制定出航班安全运行的应对措施。研究表明，近几年昆明市极端温度和极端降水事件呈现增多趋势；因地形原因，长水机场出现大雾的频率远高于原巫家坝机场；大雾造成的低能见度天气背景下，航班的安全运行需要航空公司各部门的通力协作。

Abstract：
Using regression analysis and Mann-Kendall sudden-change analyses, this research identifed the extreme temperature weather and precipitation events in Kunming city based on a collection of meteorological data records from 1951 and 2010 from Kunming’s meteorological station. Then, we outlined safe flight operations in the extreme weather conditions, especially for days with heavy fog at the Kunming Changshui airport. Finally, we provided some solutions to improve ?ight safety operations at the Kunming Changshui airport by comparing with the fog characteristics at the Wujiaba airport. This research showed that: 1) extreme precipitation and temperature events of Kunming Changshui airport have been increasing in recent years, 2) The frequency of fog occurrences in Changshui was much higher than in Wujiaba due to the surrounding landforms, and 3) ?ight safety operations need co-operation among relevant departments of the Airlines.
