So....that is my breath that I see in a cold climate; all those minuscule aerosols. Hmmm. Thought so.
Also.........The warmth of the urine creates this same phenom in cold weather. Very interesting.

I'm no rocket surgeon but I don't think what you're seeing outside in cold climates are the microscopic particles. They're in there but that's not what you're seeing. Logic also tells me that people spend more times indoors in those types of climates and your hypothesis falls apart when that happens.
On a side note, I used to be able to write my full name in the snow but nowadays I need an eraser to clean the yellow off my snow boots.......
