摘　　要：借助垂直过载增量法,结合使用飞机颠簸数据统计分析2014年四条高原航线飞机颠簸的时空分布特征,即高原航线的飞机颠簸频率在55%以上,拉萨航线高达78.8%。进离场阶段遭遇颠簸的频率高于巡航阶段。发生飞机颠簸频率表现夏秋季节低,冬春季节高。巡航阶段发生飞机颠簸的高度集中在6 900~8 700 m。进离场阶段发生飞机颠簸的频次随着高度的降低而增加。飞机颠簸空间分布呈长条形,发生飞机颠簸高频区域是拉萨航线91°E~93°E和97°E~99°E区域以及九寨航线31°N~33°N。Using the method of vertical load increment,combined with statistical analysis of aircraft turbulence data and reanalysis data,the spatiotemporal distribution characteristics of aircraft turbulence on four high-altitude routes in 2014 was investigated.The results indicate that the turbulence frequency on the high-altitude routes exceeded 55%,reaching as high as 78.8%on the Lhasa route.Turbulence encounters are more frequent during the departure and arrival phases compared to the cruising phase.The occurrence of aircraft turbulence shows a seasonal variation,with lower frequencies in the summer and fall seasons and higher frequencies in the winter and spring seasons.During the cruising phase,aircraft turbulence primarily occurs in the altitude range of 6900~8700 meters.In contrast,during the departure and arrival phases,the frequency of turbulence encounters increased as the altitude decreased.The spatial distribution of aircraft turbulence exhibits an elongated shape,with high-frequency turbulence areas observes in the 91°E~93°E and 97°E~99°E regions of the ZULS,as well as the 31°N~33°N region of ZUJZ.
