How can winter white frost can form on the ground when minimum temperature indicates well 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.

What are som facts about freezing rain?
It freezes in ground temperature and is very dangerous
What is the temperature during a thunderstorm?
Depending on many different conditions the temperature on the ground during a thunderstorm can be well below freezing (<32F) to over 100F. Inside the thunderhead clouds themselves the temperature at the bottom is above freezing but at the top the temperature is often well below freezing.
What tempateure does it snow?
The temperature in the clouds must be below freezing. If it is below freezing (32 Fahrenheit, 0 Celsius) all the way to the ground, snow will fall. If not, it will melt and reach the ground as rain, freezing rain, or sleet, depending on if it has time to refreeze. Snow can even fall if the temperature at the surface is a little above freezing if it doesn't have time to melt as it falls.
Does the temperature of air high above the ground often above or below 0C?
Where air planes fly, the temperature is below freezing.
What is the diagram for freezing and freezing point?
Absolute zero is the theoretical lowest possible temperature. More formally, it is the theoretical temperature at which entropy reaches its minimum value. The laws of thermodynamics state that absolute zero cannot be reached using only thermodynamic means. A system at absolute zero still possesses quantum mechanical zero-point energy, the energy of its ground state. The kinetic energy of the ground state cannot be removed. However, in the classical interpretation, it is zero and the thermal energy of matter vanishes.
Does it have to bebelow freezing for it to snow?
Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, of course the snow will reach the ground. In the clouds, the water droplets freeze and become ice crystals, or snow!
What conditions are required for it to sleet?
ground temperature below freezing, and air temperature slightly above freezing.
What is the minimum cooking temperature for cooking ground beef?
Ground beef should be cooked at a temperature of about 160 degrees Fahrenheit. That should be its minimum internal temperature. The external temperature to get it to such an internal temperature is up to you.
What is rain freezing temperature?
Liquid does not freeze unless the temperature is 32 degrees or less, whether it is freezing rain, snow, or sleet. The difference in what falls from the sky (snow or freezing rain) depends on where the freezing temperature is located. For example, if the temperature on the ground is 32 degrees or less, but the air temperature is warmer then 32 degrees, then the precipitation will come down as rain UNTIL it hits the ground or an object, then it freezes. If the ground and everything above the ground is 32 degrees or below, then the precipitation will come down as snow.

what tempacher is a snowy day?
Snow forms when the atmospheric temperature is at or below freezing and there is enough moisture in the air. But the temperature at the ground level may be warmer, sometimes above freezing.
Why are greenhouses completely or partially underground?
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%

At what temperature does rain convert to snow?
Most precipitation that reaches the ground actually begins as snow high in the atmosphere. These snow flakes develop somewhere above the freezing level where the air temperature is less than 32 F and begin to fall toward the earth as snow. If ground temperature is above 32 F( the freezing level must be located somewhere above the ground). The falling snow passes through the freezing level into the warmer air, where it melts and changes to rain before reaching the ground.
What is the minimum temperature ground beef should be cooked to in order to assure safety?
155*F
