摘要
颠簸是影响飞行安全的危险因素。本文利用机载实况颠簸报,统计分析影响飞行安全的中度及以上强度颠簸报的时空分布特征、颠簸时长等要素。结果表明,中度及以上颠簸呈现点状、线状、块状分布,高频区域靠近航班运行繁忙区域;夏季发生中度以上颠簸过程概率最高,颠簸过程具有日变化特征,12-14时颠簸出现次数最多,13时达到峰值;颠簸过程持续时长多在50-60 (含)min内,高度主要在FL250 (含)以下,区域颠簸高度分布与区域地形环境、气候特点有关。
Turbulence is a dangerous factor affecting flight safety.This article uses live airborne turbulence reports to statistically analyze the factors that affect flight safety concerning the characteristics of the spatial and temporal distribution,turbulence duration of moderate and severe aviation turbulence reports.The results show that moderate and severe turbulence presents a distribution of dots,lines and blocks,with high-frequency areas close to regions with busy flight operations.The probability of experiencing moderate or severe turbulence is highest during the summer months.The turbulence has daily variations,turbulence with the highest number of occurrences between 12:00 and 14:00,reaching a peak at 13:00;The duration of the turbulence is mostly between or within 50-60 minutes.The height is mainly at or below FL250 and the distribution of turbulence height in the region is related to the regional terrain and climate characteristics.
