wing-tip vortices
Wing-tip vortices.
An area of extreme turbulence below an aircraft in flight caused by the high pressure below the wing spilling over the wing tip into low pressure on top of the wing producing a tight spiral, or a vortex of air.

As part of the ACEE effort, Langley Research Center aeronautical engineer Richard Whitcomb conducted computer and wind tunnel tests to explore his hypothesis that a precisely designed, vertical wingtip deviceNwhich Whitcomb called a OwingletONcould weaken wingtip vortices and thus diminish induced drag.
It wasn't a KC-135 Iron Maiden or a wingtip-podded KC-130 complete with the associated wingtip vortices.
API's Blended Winglets are an addition to the aircraft wing tip which is designed to efficiently add effective wingspan, reduce the drag caused by wingtip vortices to increase fuel efficiency and boost range.
The BOL system uses wingtip vortices to distribute the chaff- and IR payload, which greatly improves dispersion and the rapid formation of a protective cloud, while avoiding the need for pyrotechnics and making it quicker, easier and safer to load the system.
The Winglets reduce the drag caused by wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface.
