"WebSometimes the swirling flow is turbulent and so energy- laden that any aircraft entering into this region of flow will face the possibility of being upset. This is called wake turbulence, and thus if the vortex strength is large enough to cause the ‘upset’ of a following aircraft, the separation between it and any following aircraft as they approach a runway has to be … " - Hierarchical vortex regions in swirling flow
