A jet engine contrail highlights a zone of shearing winds in the atmosphere. In this photograph you see a contrail that has been overturned by shearing winds (winds that have changing horizontal velocties at different elevations). It appears (upper right) that the original contrail has been spread out by further cloud growth processes into a different cloud formation, namely stratocumulus.
