Frost is a layer of fine ice crystals that form during cold nights on the surface of plants on car windows and windshields. They can occur from late fall to early spring.
Frosts come from the cooling of water vapor in the air. They appear on cold, windless nights with clear skies. The surface of the plant or object must be sufficiently cool. Ambient cold (below zero) is not necessary. However, there must also be sufficient humidity.
Frosts are usually signs of a beautiful day.
We can also have gel flowers. Frost flowers look like ferns or take the form of feathers. Their formation begins with classic frosts with 6-pronged ice crystals. The crystals will then grow slowly following the original crystal structure.
