    There's been no frosts here recently, according to the weatherman and according to the look of the place in the mornings. But my car has a roof covered in what looks like frost the last few mornings.

    But there's none anywhere else.

    Why's this? How could it be? What's going on? A sub-zero stream of air at the height of my car roof? The metal of my car sinks to a lower temp than anything else?

    Well, I'd say the dew point and the freezing point (pressure sensitive) have had a brief and delicate encounter and wound up being visible on only highly thermally conductive surfaces with low specific heat content - and the roof of your car was a good candidate!

    Well thanks for that. I'll google it around until I understand it and I'm sure I'll benefit from the experience. Thanks again.
