Frosty Pine Bough Sunrise
Toward obtaining an image at -2 degrees F. There was a breeze and I don’t care how you dress, something gets cold lolol.
This Close Far perspective is a favorite way to deal with first light of morning. Fortunately this ridge had a 1/8 inch of Hoar Frost covering all the vegetation. I call these “Pine Noodles” as it just seems to fit. The earliest light as the sun is just rising has a decidedly pink color cast. Usually this is most obvious on the sky opposite the sunrise. The “Belt of Venus” which is a very pink Alpenglow phenomena reflecting said pink light back. Pine Needles coated in ice make a very good projection/reflection screen. This pink color cast is not that common on local vegetation and is usually only perceptible on the atmospheric ice.
Hoar Frost usually forms on objects disrupting air flow. The air full of moisture under freezing conditions. DIrect condensation of that vapor from supersaturated air is greater then 100%. The formation of hoar frost is similar to the formation of regular dew with the difference that the temperature of the object on which the hoar frost forms is well below 32 degree F., whereas this is not the case with dew. Hoar frost crystals often form initially on the tips of plants and or other objects. I’ve seen vehicles, fences, tires, plants and even other icicles with Hoar Frost on them. The largest I’ve seen had frost feathers/needles almost 2 inches long.
