What is the difference between a vortex and an eddy?

WebSeen from behind, this vortex is rotating anti-clockwise. When the left wing of the follower first enters the vortex, there is on this wing a local angle of attack increase and therefore the lift becomes higher than on the right wing. The initial roll motion is therefore to the right. WebWake turbulence can occasionally, under the right conditions, be heard by ground observers. On a still day, the wake turbulence from heavy jets on landing approach can be heard as a dull roar or whistle. This is the strong core of the vortex. If the aircraft produces a weaker vortex, the breakup will sound like tearing a piece of paper. how far back can i claim employment allowance
