Because the temperature is often a few degrees colder right at the surface. This is because cold air sinks, and if it is not mixed (as under calm conditions) the temperature will be colder at the surface than it is 2 meters above ground, where temperature is officially measured.
Frost can occur when temperatures are at or below freezing, typically between 28 to 32 degrees Fahrenheit.
Frost can form above freezing temperatures when the air temperature drops below freezing, causing the moisture in the air to condense and freeze on surfaces like grass or car windows. This process is known as deposition.
The temperature above freezing is any temperature above 32 degrees Fahrenheit (0 degrees Celsius).
Rain will fall when the air temperature is above freezing.
It can't if it is "well" above freezing, but certainly if it is only a few degrees. The surface on a calm, cold night will radiate heat away from it rapidly. If there is little wind to mix the air, the coldest air near the surface will sink to the ground so that the temperature right at the surface where frost forms is at or just below the freezing point, while just above that where temperature is officially measured (2 meters) it can be several degrees warmer.
To take advantage of the constant temperature of the ground below the frost line. While it is freezing above ground...beneath the ground maintains an average temperature of 75%
the definition of frost is:ice that has been deposited on a surface with a temperature that is below freezing. so yeah.
Frost forms when the temperature drops below freezing, typically around 32 degrees Fahrenheit (0 degrees Celsius).
Frost starts to form when the temperature drops below freezing, which is 32 degrees Fahrenheit or 0 degrees Celsius.
no its freezing cold because it is past the frost line.
about above 0 degrees but it would be better if it was above freezing about above 0 degrees but it would be better if it was above freezing
In the polar region/zone, the temperature seldom rises above freezing. Ice Cap A+
