Which type of fog is more persistent than radiation fog?

Advection fog is indeed more persistent than radiation fog due to the conditions under which it forms and its characteristics. Advection fog occurs when warm, moist air moves over a cooler surface, causing the moisture in the air to condense into fog. This type of fog can last for extended periods because it is often associated with larger weather patterns, such as maritime air masses, which can maintain moisture, allowing the fog to persist as long as the conditions remain favorable.

In contrast, radiation fog is typically more localized and dependent on specific nighttime cooling conditions. It forms when the ground loses heat rapidly after sunset, leading to temperature inversions near the surface. This type of fog is usually short-lived and dissipates quickly once the sun rises and the ground warms up again.

The other types of fog listed do not have the same persistence characteristics as advection fog. Steam fog arises when cold air moves over warm water, leading to vapor condensation, while ground fog is often just a variant of radiation fog that forms close to the surface. Cloud fog, or fog that forms within clouds, does not have the same persistence issues, but its formation and longevity depend more on cloud layer conditions than on ground temperature gradients. Hence, advection fog's connection to persistent weather conditions
