A common cause of ground or surface temperature inversion is terrestrial radiation on clear nights with light winds. During the night, the Earth's surface loses heat through radiation, cooling down more rapidly than the air above it. This cooling effect can lead to a situation where the air close to the ground becomes cooler than the air above it, creating an inversion layer. Inversions are typically more pronounced during clear nights when there is little wind, as the stability of the atmosphere is maintained, allowing this temperature gradient to form.

In contrast, heating air by subsidence involves sinking warm air, which typically leads to rising temperatures and can disrupt a temperature inversion rather than forming one. Rapidly lifting warm air aloft would similarly oppose the establishment of an inversion. The movement of colder air under warm air can also contribute to the development of certain atmospheric layers, but it does not directly relate to the mechanism behind surface temperature inversions as effectively as terrestrial radiation does.
