In this paper, two coherent Doppler lidars were used to observe the low-level wind shear induced by dry thunder storms and terrain at Beijing Capital International Airport. The experiments respectively adopted Doppler Beam Swing (DBS) and Glide Path wind shear identification method to alert the wind shear of the above two types. The results show that the DBS method and Glide Path mode can respectively identify horizontal wind shear caused by dry thunderstorms and terrain. Dry thunderstorms bring sudden increase of wind velocity, abrupt change of wind direction and strong convection of updrafts and downdrafts, which causes the low-level wind shear. Terrain-induced wind shear with the transient and sporadic nature is mainly produced by the interaction between high-speed airflow and complex underlying surface.
