垂直切变 meaning in English
vertical shear
Examples
- As the strong normal share of the wind , turbulent fluctuation is strengthened and the sands are raised up from the surface ground the wind speed in the atmosphere of the low level has a horizontal share and this pushes the sands in the atmosphere aggregate , so the visibility descend
近地面风速的垂直切变和地面热通量的加大，都可使使边界层湍流加强扬起地面沙尘。地面锋区附近风场的强水平切变，锋面垂直环流及锋后斜压转换的作用，将地面卷起的沙尘带到高空，爆发强沙尘暴。 - Based on the sha lo wan profiler data at 0740utc , the vertical shear at around 1 , 100 ft was close to 8 kt per 100 ft . although this was lower than the 8 kt per 100 ft which has been used in the windshear warning system at the old kai tak airport , the increase in head wind was nonetheless significant due to the steep climb angle
根据沙螺湾的气流剖析仪在0740utc录得的资料显示，在约1 , 100尺的垂直切变接近每百尺每小时8海里。虽然此切变低于以往启德机场的风切变警报系统所用的每百尺每小时8海里，但因为陡峭的爬升角度，令到逆风的增加变得显著。
