Abstract:

Low-level wind shear can affect aircraft during taking-off and landing phases and the structure of wind turbines in disastrous ways. The principle and parameters of coherent Doppler lidar (CDL) were explained briefly and the method of retrieving wind profiles from line of sight ( LOS ) wind speed in detail. The data analysis is based on CDL configured at Beijing Capital International Airport (BCIA) in spring of 2015. Wind profiles time series and wind speed gradient were illustrated to identify the low-level wind shear. The results show that CDL is an effective tool to capture the low-level wind shear events.

Key words: low-level wind shear, coherent Doppler lidar, wind profiles
