windshear 中文意思是什麼

windshear 解釋
風切變
  1. Impact of windshear on ascending or descending air crafts

    風切變對升降中航機造成的影響
  2. 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
