[pianotech] How does fog freeze?

[George F Emerson]

I have seen this, in Alaska.  I think another component to this phenomena is the absence of the slightest breeze.  Like a dandelion, it all blows away with the slightest puff of wind.

  The UK has had a cold December. In the West of Scotland, temperatures have not been rising above freezing (0C) all day. Last week, we had days of fog. Moisture condensed out of the freezing fog to produce fronst crystal formations the like of which my work colleagues and I (all in our 50s) agree we have never seen.

  Sorry this is off-topic, but its beautiful!

  Remember, this is frost, not snow.

  Best wishes,

  David Boyce.


    How does fog freeze?  Can you see through it when it freezes?  Or, do you drive into a cement fog wall?  J
