In the same spirit of pedantry, it's a great picture featuring a temperature inversion but it's not a picture
of a temperature inversion because the human eye can't see the temperature of the air, or convection currents within it directly: a temperature inversion is invisible.
In order to see one, there needs to be something in the air that makes the convection (or lack of it) visible. Smoke would do. Or, as in Tim's picture, water vapour that has condensed out into a mass of tiny airborne droplets of water - that is what makes the inversion visible.
Now, what's a good snappy name for a big fluffy looking aerosol of tiny airborne water droplets dominating a landscape? One that, but for the inversion going on, would be much higher in the air. Hmm...
