What is Hoar frost? December 6, 2012

On the 2nd day of December…mother nature sent to me, “a hoarfrost and snowy evergreen trees”

Welcome to the land of the Great White North, also known as Canada! It really doesn’t snow all year long, and we don’t live in igloos! Only since, living in Calgary, Alberta, which is about 1 hour drive from the famous town of Banff which is nestled in the mountains, have I discover experiencing a hoar frost. Taken from Wikipedia, the definition is “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. A related effect is flood frost which occurs when air cooled by ground-level radiation losses travels downhill to form pockets of very cold air in depressions, valleys, and hollows. Hoar frost can form in these areas even when the air temperature a few feet above ground is well above freezing. Nonetheless the frost itself will be at or below the freezing temperature of water.”

It really feels like you have just landed in Narnia! A hoar frost is stunning beautiful, every tree and bush is lined with ice crystals! It usually doesn’t last for too many days, and if you are really lucky you get a dump of snow, that then sticks to the landscape, making it even more breath taking.

On Sunday, I was determined to go out for a walk, to take a picture, as I already missed last weeks opportunity, and was so thrilled that a hoar frost had returned! I dressed up in my layers, as it was -10 Celcius (without the wind chill) and took this landscape just a block around from my home. Brrr…time to warm up, get the crackling fire roaring, and pour yourself a cup of hot chocolate. Christina
