curious and delicate

Feathery Frost by Jo Bradford


It has been unusally frosty here this week!!

Frost: Definition~Atmospheric moisture that freezes directly on the ground and on exposed objects.

Frost Facts:

Frost formation occurs when water vapour in the atmosphere passes into the ice-crystal phase without going through the intermediate liquid phase. Frost forms under conditions that would form dew if the temperature were above freezing.

Ice formed by the crystallisation of atmospheric moisture (water vapor) on a surface when the temperature of the surface is below 32°F (0°C).

Frost often appears as a light feathery deposit of ice, often of a curious and delicate pattern.
