Triggering Mechanism of an Extreme Rainstorm Process near the Tianshan Mountains in Xinjiang, an Arid Region in China, Based on a Numerical Simulation

Figure 7

Vertical cross sections of simulated radar reflectivity (shaded, unit: dBZ) and wind vectors (arrow, unit: m·s⁻¹; for the convenience of analysis, the vertical velocity is multiplied by 10, and gray shading represents the terrain of the Tianshan Mountains, the same as below) along the black solid line shown in Figure 5. (a) Along AB in the initiation stage at 12:00 on July 31. (b) Along CD in the initiation stage at 12:00 on July 31. (c) Along AB in the development stage at 16:00 on July 31. (d) Along CD in the development stage at 16:00 on July 31. (e) Along AB in the maturity stage at 17:30 on July 31. (f) Along CD in the maturity stage at 17:30 on July 31. (g) Along AB in the extinction stage at 22:00 on July 31, 2016. (h) Along CD in the extinction stage at 22:00 on July 31, 2016.
