Analysis of wind field measurement results of Doppler lidar

The wind profiles measured by a Rayleigh Doppler wind lidar are in good agreement with the pilot balloon wind profiles. The maximum discrepancy of the wind profiles of both the lidar and the pilot balloon is 3 m/s below 10 km and 4.5 m/s below 20 km. The maximum standard deviation of wind direction is 32 except for the inflexion at about 20 km altitude. The sequential detection results made by the lidar show the clear intense westerly jet with a local maximum speed of 70 m/s at about 10-12 km altitude, and a local minimum speed no less than 30 m/s. The minimum wind speed is less than 1 m/s at about 20 km altitude and wind speed increases with the altitude increasing above the inflexion. The wind direction is west wind of about 270 below the inflexion and east wind of about 90 above the inflexion. The capability of Rayleigh Doppler wind lidar, tracking the variation law of large scale season climate characteristics while giving prominence to the forming and evolving procedure of small scale transient climate characteristics, has been demonstrate.
