condensation trail 【航空】凝結尾〔噴射機經過后肉眼可見的白帶狀水氣凝結物〕...

condensation wave

Condensation trails ( contrails ) are formed high in the sky where water vapour from aircraft exhaust condenses in the surrounding cold air , producing water droplets andor ice crystals . they appear as narrow , sometimes rather straight , streaks on satellite cloud images 飛機在高空航行時排出水氣,水氣被周圍的冷空氣冷凝下來,結成水點或冰晶,在高空留下了一條痕跡,稱為凝結尾跡。

Scientists have long known that airplane condensation trails act to both cool and heat the atmosphere 科學家早已知道,飛機后方的凝結尾對大氣同時具有冷卻與加溫的效果。

The word “ contrail “ comes from condensation trails 英文“ contrail “意即是凝結
