Wake vortex in the fog as an airplane lands

Wake vortex! An invisible but universal phenomena, huge wingtip vortices can be seen in the twisting fog as this airplane lands in Zurich, Switzerland. Wingtip vortices are strong spirals of air that are created when high pressure air below the wing spills up around the top of the wing, a relatively lower air pressure space, making a small horizontal tornado.
