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

Figure 3

The TDWR radial velocity plot at 0.6-degree conical scan at the time of terrain-induced microburst, that is, 05:36:24 a.m. of 21 July 2015. Higher wind speed streaks are indicated by solid red arrows, and lower wind speed streaks are indicated by dashed red arrows. The time displayed is in Hong Kong time (UTC + 8 hours). The vertical cross sections AB, 4-4′ and 1-1′, are shown in (b), (c), and (d), respectively.
