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.

低空风切变定义
• 根据国际民航组织的有关文件和文献约
定，低空风切变主要是指航空器起飞和着
落阶段，飞行高度在500米以下发生的，在
同一高度或不同高度短距离内风向和
（或）风速的快速变化，而这种变化须达
到某一数值（30米厚度的气层的上下风速
变化达到2米/秒为中度以上）的天气现象
