Talk:Hoar frost

Hoar frost or hoarfrost? ({{Abbr|Posted without title|Title added by User:Askarion on December 2, 2023}})
All the dictionaries that I've consulted spell hoarfrost as one word. Kelisi 04:54, 22 September 2005 (UTC)

Where does the name hoar frost (or hoarfrost) come from?


 * I'd imagine it's because the frost looks like a hoary beard. Dictionary.com defines "hoar" thusly: adj : showing characteristics of age, especially having gray or white hair; "whose beard with age is hoar"-Coleridge - Brian Kendig 17:55, 12 January 2006 (UTC)

Question about hoar frost ({{Abbr|Posted without title|Title added by User:Askarion on December 2, 2023}})
I have been reading about frost in different forms, and regarding Hoar frost I have this one question: Take e.g a sailboat on shore in winter. It`s -15 degrees Celcius. The boat has a plattform on the stern. The boat is covered by a big plastic cover hanging over the mast lying on top of the boat stretching only over half of the plattform, leaving the other half under open sky. It is 2 meters from the platform up to the plastic cover. Why is Hoar frost only forming on the part of the platform sticking out beyond the edge of the cower. I mean, the cover is 2 meters up. The temperature under the cover and outside of the cover has to be nearly equal, anyway far beyond freezing point. Do the moist air "rain" down slowly? I have seen this many times, and I am puzzled by it. The strange thing is that the line between area with Hoar frost and area without (totaly) is wery sharp., directly vertical under the edge of the cover hi up there. Bjarne Kristensen Norway
