Milt, still without explanation, I recall that there was extensive RAE research into wake turbulence which involved photos of contrails. I cannot locate any references; circa 1970s.
You might wish to contact Genghis who should have contacts in this area.

Alternatively, read up on chaos theory; interactions of vortex systems.
