Where is radiation fog most likely to form?

Radiation fog is formed when the ground loses heat through radiation, particularly during calm, clear nights. This cooling process allows the air near the surface to reach its dew point, resulting in condensation and the creation of fog. The absence of wind helps maintain a stable layer of cool air near the ground, which is essential for the formation of radiation fog.

The other scenarios do not favor the development of radiation fog as effectively. For instance, windy conditions can lead to mixing of the air, preventing the localized cooling required for fog formation. Coastal areas could experience other types of fog, but often not radiation fog specifically during winter, as maritime influences generally keep the air temperature more stable. Fog in urban areas tends to relate more to other factors, such as pollutants and localized heating, rather than the quiet radiative cooling that is necessary for radiation fog formation.
