摘要
为评估云南丽江机场的气象条件状况,确定气象要素的周期性变化特征,为机场航空安全提供保障基础,对2007-2020年丽江机场的常规气象观测资料、2013-2020年丽江机场航空器空中报告资料及1943-2019年的ERA5逐小时再分析资料的进行分析。运用多种统计和诊断分析方法探究丽江机场区域的气候特征及其变化规律。研究表明,丽江机场主要的气候参数,包括气温、气压、相对湿度、降水量和风速等,均展现出显著的季节性变化。在多数情况下,该机场的能见度和低云层维持在理想状态,尽管雨季时雷暴较频繁,但总体而言,依然符合飞行安全的标准。通过小波分析发现,降水和气温呈现出3年、7年及22年的周期性波动,同时在气温方面还观察到9年和51年的长期周期变化趋势。
To assess the meteorological conditions at Lijiang Airport in Yunnan,and to determine the periodic variations of meteorological elements,providing a basis for aviation safety at the airport,an in-depth analysis was conducted on the routine meteorological observation data from 2007 to 2020,aircraft airborne reports data from 2013 to 2020 at Lijiang Air-port,and hourly reanalysis data from ERA5 covering the years 1943 to 2019.By utilizing a variety of statistical and diag-nostic analysis methods,this research thoroughly explores the climatic characteristics and their changing patterns in the region of Lijiang Airport.The study reveals that the main climatic parameters of Lijiang Airport,including temperature,pressure,relative humidity,precipitation,and wind speed,all exhibit significant seasonal variations.In most cases,the visibility and low cloud cover at the airport remain at ideal levels.Despite more frequent thunderstorms during the rainy season,the overall conditions still meet the standards for flight safety.Wavelet analysis has identified cyclical fluctuations in precipitation and temperature over 3,7 and 22 years,and longer cyclical trends of 9 and 51 years in temperature.
