Figure 8

Streamlines and contour of wind speed in the flat and gorge terrains at different typical time. (a) Flat terrain, t = 50 s. (b) Gorge terrain, t = 50 s. (c) Flat terrain, t = 100 s. (d) Gorge terrain, t = 100 s. (e) Flat terrain, t = 150 s. (f) Gorge terrain, t = 150 s. (g) Flat terrain, t = 180 s. (h) Gorge terrain, t = 180 s. (i) Flat terrain, t = 210 s. (j) Gorge terrain, t = 210 s. (k) Flat terrain, t = 240 s. (l) Gorge terrain, t = 240 s.
