The science behind frost development

AUSTIN (KXAN) -- The formation of frost is a relatively simple process, relying on a few atmospheric conditions. First, the surface temperature of the ground must be at or below freezing. While the ground temperature may be at freezing, the air just above the surface is typically a few degrees warmer due to sinking cold air.

Moisture in the air is essential for frost to form. When the temperature of the air drops to the dew point, the water vapor...
