Overview |
Distrails
|
Here the opposite process of contrail formation caused by air traffic is shown: a cloud area was destructed by an aircraft. This aircraft flies in dry air above the Cirrocumulus cloud layer. The dry surrounding air around the aircraft is blown top down into the cloud cover by the downwards acceleration of air behind the wings ("downwash"). |
A turbulent mixture of cloud air with dry air from the top arises and an "aisle" is cut into the Cirrocumulus cover. So a kind of "negative contrail" is formed also named "distrail". |
