hoar frost


It was frosty today in the morning, second time in a row. I had to spend some happy time with ice scraper before we could start for school.

While checking for the correct name of this type frost (yes, I am a checking person), I found the name for another type of frosty formations that I saw only ones before. I didn't see any today, but basically it looks like thin flat same-width rims of ice. Pics that I took on one occasion I saw it - here and here

According to wikipedia it's called advection frost or wind frost and it forms _against_ the wind direction. A puzzler that.
