ground frost temperature

True frost, known as hoar frost, occurs when a thin layer of moist air near the ground cools to below freezing and immediately forms ice crystals. Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above freezing atmosphere coming in contact with a solid surface whose. Frost forms in much the same way as dew forms. Frost usually forms when a surface cools through loss of infrared radiation to a temperature.

Frost forms when: the dew point is at or below freezing. When the air temperature cools to the dew point and further cooling occurs, water vapor can change. Frost crystals grow from water vapor in the air, just like snow crystals (see the Snowflake Primer). But while snow crystals form on suspended dust particles high. Frost can form when the air temperature is a few degrees above freezing when the sky is clear and the wind is light or calm.
