Abstract
Based on the analysis of the characteristics and principles of the major detectors of low level
wind shear in the world , the result can be applied to use the detectors in the future. On the base of
the analysis of low level wind shear occurred in Shanghai airports, some predictive points are
established.

低空風切變定義
• 根據國際民航組織的有關文件和文獻約
定，低空風切變主要是指航空器起飛和著
落階段，飛行高度在500米以下發生的，在
同一高度或不同高度短距離內風向和
（或）風速的快速變化，而這種變化須達
到某一數值（30米厚度的氣層的上下風速
變化達到2米/秒為中度以上）的天氣現象
