摘　　要：卫星云图上有很多特殊的云型都与飞机颠簸相联系,有的甚至会出现严重颠簸,对它们的识别,对保障飞行安全有重要意义。本文根据2006年的风云二号卫星云图资料,统计和分析了我国高原地区产生飞机颠簸的大尺度云系的出现和分布规律。分析表明:在我国高原地区,产生飞机颠簸的大尺度云系主要有高空急流云系、未闭合的细胞状云系、山地波中的波状云系和积云线。这些大尺度的云系主要出现在我国的青藏高原,在这些云出现的地区飞行,都会出现中度到强烈的飞机颠簸。In satellite photograph of cloud,there are many special type of clouds associated with the turbulence,and some even lead to serious bumps,identifying these is very important for ensuring air flight safety.This article is based on the 2006 FY-2 satellite image data.It tallied and analyzed the large-scale cloud systems＇ appearance and regularity in plateau of China.Analysis shows that： In the plateau region of China,those significant components of large-scaled clouds system that makes airplane turbulence are High-altitude jet cloud、Unclosed-cell-like cloud、Wave cloud in mountain waves and cumulus cloud lines.The large-scale cloud systems are mainly in China＇s Qinghai-Tibet Plateau.Fly on those districts with large-scale cloud systems will cause moderate or strong airplane turbulence.

关 键 词：高原地区 飞机颠簸 大尺度云系
