Sorry you thought it "drivel" (Good word choice, though).
Look....I'll try again:
Airplane is in flight, and as is common today, using GPS to perform a precise turn that, on a radar ground track, would describe a normal circle, in
the same place in relation to the ground.
This same airplane, whilst doing this, is staying at the SAME altitude, mind you. And, it is, for the purposes of this explanation, whilst doing this
"orbiting", happens to be forming contrails in its wake.
With me so far?
THOSE contrails, once formed, are not "controlled" by anything other than the prevailing winds aloft. The airplane, recall --- is using GPS to
remain situated over a particular place, in relation to the surface of the Earth.
(and the contrails, free to be affected now, by that wind) can carry those contrails "downstream" (to use another [water]
DO YOU UNDERSTAND YET???
I can try more examples (and analogies)....but, perhaps you haven't even yet opened the link that I posted??
