Ice Fog

What a difference 20 or so degrees makes! I took this a couple of days ago out at North Pole when the temperature was below minus forty. As you can see, the ice fog was pretty thick. Today the temperature is way way up around minus twenty and the fog is all gone.

When it's quite cold out and the air is still, any moisture, water from automobile exhaust, that coming out the chimneys of each house's heating system, even our exhaled breaths, freezes instantly in to tiny ice crystals so small they just hang in the air. Hence ice fog.

The colder it is, the stiller the air, the longer it stays cold, and the greater the water vapor producing populace, -the thicker the ice fog!

The Russian word for ice fog translates as 'habitation fog'. Quite apt.
