A temperature at or below freezing is not absolutely necessary to get ground frost or hoar frost; they can form even if air temperature is marginally above freezing point if the sky is clear. This is because the ground loses heat due to radiation. It radiates its heat to the sky/space. The amount of heat that radiates is proportional to the difference of the fourth power of the temperatures between the two objects. At night, the atmosphere is not being warmed by the sun and the sky/…
