Snippet: As can be seen from Figs. 11, 12, when the upper end is open, the lower end is not permeable to the wind, and the wind shadow area is the largest. The wind speed amplification factor at the upper end is the largest. As the hole moves downward, the range of the lower wind shadow area gradually decreases, and the range along the horizontal direction also gradually decreases, but the upper part gradually produces a wind shadow area along a vertical .....
Document: As can be seen from Figs. 11, 12, when the upper end is open, the lower end is not permeable to the wind, and the wind shadow area is the largest. The wind speed amplification factor at the upper end is the largest. As the hole moves downward, the range of the lower wind shadow area gradually decreases, and the range along the horizontal direction also gradually decreases, but the upper part gradually produces a wind shadow area along a vertical direction. The distribution of the upper wind speed gradually tends to fluctuate.
