不同的高原产生大气湍流的条件不尽相同,因此航线上飞机颠簸的出现规律也不一样。分析青藏高原和云贵高原的地形差异和气候区别,并根据四川航空公司的机载QAR数据,对青藏高原和云贵高原的飞机颠簸出现次数、出现概率和颠簸强度进行统计,对比分析了青藏高原和云贵高原航线上飞机颠簸的出现和分布规律,为高原航线飞机颠簸的预报和航行签派工作提供重要参考。 The conditions of atmospheric turbulence produced by different plateaus are not the same, so the regularity of occurrence of aircraft bumps on the route is also different. Based on the airborne QAR data of Sichuan Airlines, the number of aircraft bumps, the occurrence probability and bumpiness of the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau were statistically analyzed, and the differences between the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau were analyzed. The occurrence and distribution of aircraft bumps on the Yunnan-Guizhou Plateau routes provide important reference for the prediction of aircraft bumpiness and dispatching of vessels on the plateau routes.
