Hoar frost

Hoar frost (also called radiation frost or hoarfrost or pruina) refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form on cold clear nights when heat losses into the open skies cause objects to become colder than the surrounding air

Photographs I took at my parents' house in Norfolk over Christmas. Have you ever seen hoar frost before? This was the first time in my life as far as I can remember.

  1. Really? I see it a lot. We must have the right conditions for it. It's especially beautiful on the trees in the Victorian cemetery behind my house.
