Re: (meteorobs) streetlights in the cold....
Would you mind expanding on these? I'm still at a loss for why a
cylindrical beam of light appears.
I have never observed this phenomenon but one possible explanation would be
the temperature inversion that must occur near the ground on
very cold nights which would certainly refract the light upward as it does
in the desert giving the elusion of water where there is none,
the mirage. That is just a wild guess, no more since I have never observed
it.
