【摘要】 飞机颠簸是影响飞行安全的重要因素,飞机颠簸的分布规律和预报方法一直是航空气象研究的重点。由于飞机颠簸资料很难获取,目前对飞机颠簸分布规律研究的很少,然而管制人员和签派员迫切希望了解飞机颠簸分布规律。鉴于此,本文阐述了与飞机颠簸有关的气象条件和物理量场,以及我国西南地区航空气候特点。通过统计我国西部干线飞机过载数据,得出我国西部干线航线飞机颠簸出现的高度和概率,总结西部干线颠簸的分布规律。最后通过个例分析,说明物理量场与飞机颠簸的关系。本文研究的主要内容包括:(1)分析飞机颠簸与物理量场的关系;(2)收集飞机颠簸实际观测资料及QAR数据;(3)分析我国西部干线飞机颠簸的出现及分布规律,内容包括不同航线的颠簸发生次数、出现高度、出现时间及不同强度的颠簸出现概率;(4)总结我国西部干线飞机颠簸出现和分布规律;(5)对有代表性的颠簸个例进行气象原因分析。研究表明,通过对我国西部干线飞机颠簸出现和分布规律的研究,总结现有航线的颠簸分布情况,研究成果对估计西部干线颠簸出现区域,出现高度和强度提供理论基础,对做好飞机颠簸预报、搞好航班安排和签派放行有重要意义。更多还原

【Abstract】 Airplane turbulence is an important factor affecting flight safety, airplane turbulence distribution law and prediction methods are always the focus of aviation meterological study. As the airplane turbulence data is difficult to obtain, there have been few studies into the distribution law of airplane turbulence, which air traffic controllers and flight dispatchers are eager to know though. In view of this, weather condition, physical quantity field and climate characteristics of China related to airplane turbulence were discussed in this paper, and then, the height and the probability of airplane turbulance were obtained through overload statistics of China’s western trunk air routes. Western trunk routes turbulence was summarized. At last, the relationship of airplane turbulence and physical quantity field was analyzed.The main research contents of this paper include:(1) Meteorological analysis was made for representative case.(2) Actual observation data of airplane turbulence and QAR data were collected.(3) The appearance and distribution of airplane turbulence of western trunk air routes were analyzed, including turbulence occurrence times of different airlines, appearance height, appearance time and turbulence probability of different intensity.(4) The appearance and distribution law of airplane turbulence of western trunk air routes were summarized.(5) The relationship of airplane turbulence and quantum field theory was analyzed in combination with airplane turbulence of western trunk air routes.This paper explored the appearance and distribution law of airplane turbulence of Chian’s western trunk air routes, and summarized turbulence distribution of current airlines. The research result provided theoretical basis for forecasting appearance zone, height and intensity of airplane turbulence of western trunk air routes, also is significance for improving airplane turbulence forecast accuracy, flight arrangement and dispatch.更多还原
