The vortex circulation is outward, upward, and around the wing tips when viewed from either ahead or behind the aircraft. 18. WebWake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air. It includes a variety of elements, the most significant of which are wingtip vortices and jetwash. Jetwash refers to the rapidly moving gases expelled from a jet engine; it is extremely turbulent but of short duration.
