摘要:
利用FNL再分析资料和卫星云图，对2015年1月11日至12日期间发生在中南管制区域的20次飞机颠簸事件进行分析，结果表明：（1）飞机颠簸事件是由高空槽过境引起，槽前有非常明显的高空急流，颠簸区域随着高空槽的东移而向东移动。（2）颠簸区垂直方向上主要发生在300hPa高度附近，水平方向上则位于急流轴的右侧风速切变的最大区域及不同风速的交界处。（3）此次系列颠簸事件多数发生在盾状卷云区，可结合卫星云图资料对颠簸区域进行识别和预报。
Abstract:
Based on the FNL reanalysis data and satellite cloud images, 20 aircraft turbulence events occurred in the central south air traffic control region during 11-12 January, 2015 were analyzed. The results show that (1) the turbulence events were caused by the transiting of high-altitude trough. There was a very obvious high-altitude jet in front of the trough, and the turbulence area moved eastward with the trough moving eastward. (2) The turbulence occurred mainly near the height of 300hPa in vertical direction, in the horizontal direction, it occurred at the maximum area of wind shear on the right side of the jet axis and the junction of different wind speeds.(3) Most of the turbulence events occurred in the shield cirrus region, so satellite cloud images were useful in identifying and predicting the aircraft turbulence.
