Why does cold air seem to optically zoom in far-away objects?

  • #1
I have noticed that cold air makes far away objects, such as mountains, appear closer than they do in warm clear weather. Does anyone have an explanation for this?

How exactly? Taller? Or clearer?
They appear larger than when the air is warm. I already stated comparison to a CLEAR warm day, as heat can make the air hazy and of course that would affect their visibility.

Try taking photos to compare?

A temperature gradient can act like a lens, and make objects seem taller.
