Observation and Numerical Simulation of Terrain-Induced Windshear at the Hong Kong International Airport in a Planetary Boundary Layer without Temperature Inversions

Figure 7

The GLYGA display at the time of low-level windshear. The left hand side is the 3-degree conical scan of radial velocity of the LIDAR, and the curves in the middle are the headwind profiles (headwind refers to the landing direction of the aircraft in the respective runway). The significant windshear is highlighted in a blue block.
