Whirlpool of air caused by spillage of air around the wing tips is called a(n):

Explanation:
When a wing generates lift, air from beneath the wing, at higher pressure, moves around the wing tip to the lower-pressure region above. That flow curls and forms a concentrated, rotating bundle of air that trails behind the wing. This rotating flow is a vortex—a coherent swirl of air. It’s more specific than just a wake or random turbulence, and it’s more defined than a general eddy. A wake is the broader disturbed region behind the aircraft, which includes the wingtip vortices but isn’t the swirling motion itself. Turbulence refers to irregular, chaotic fluctuations, not the steady, circulating structure of a wingtip vortex. So the whirlpool of air around the wing tips is a vortex.
