Today was, for sure, the coldest day this year, well it is only the 4th January!
Happy New Year to all of you.
The hoar frost lasted all day turning our orchard into a real winter wonderland. A few of our customers braved the cold and enjoyed a quick walk around the orchard but most were happy to sit by the log burner and view the frosty trees from the warmth of our cosy tea room.
So here are 5 things about hoar frost:
1. Hoar frost id also called radiation frost or hoarfrost or pruina.
2. Hoar frost forms on cold clear nights when heat losses into the open skies cause objects to become colder than the surrounding air.
3. Hoar frost is white ice crystals deposited on the ground or on objects such as the plum trees pictured above.
4. The word hoar comes from the old English adjective for showing signs of age.
5. Hoar frost also occurs in man made environments eg. freezers and cold stores.
