Whoa! A "clear air tornado"?
Surprised the hell out of me as well. I did some research own it years ago
and it seems to be related to a better known clear air micro burst.

Just a guess here, but tornados take on the color of the ground they are
crossing over... black topsoil - black tornado, yellow dirt - yellow
tornado, water - white tornado. My guess would be a clear one wouldn't be
on the ground?
