Application of Short-Range LIDAR in Early Alerting for Low-Level Windshear and Turbulence at Hong Kong International Airport

Figure 4

Radial velocity fields in the short-range LIDAR PPI. Each pixel in the image represents 30 meters in the radial direction, with time difference of 40 seconds between images. (a) shows a relatively even radial velocity field for background wind over the 25RA descent glide path. (b) shows airflow disturbance over the 25RA descent glide path. (c) shows airflow disturbance left from the 25RA descent glide path.
