I became a believer in small waterspouts / tornadoes generated by heavy
aircraft on final approach into SFO, after seeing them myself within 30'.
(Wasn't previously sure whether to believe others when they spoke of this...)
My understanding is that heavy aircraft wake turbulence is generally
believed to consist of horizontal axis rotation, not the vertical axis we see on
the water while sailing.
Any of you ever develop theories or research this? Heavy aircraft captains I
know are interested in our observations or knowledge, and concede that wake
turbulence is poorly understood by NASA, pilots, et al.
