Can advection fog be burned off by the sun?

Advection fog is formed when warm, moist air moves over a cooler surface, resulting in the condensation of water vapor into tiny droplets. This type of fog typically forms in coastal areas where warm air from the ocean moves inland over cooler land.

Burning off fog generally refers to the phenomenon where the sunlight increases the temperature of the air, causing the fog to evaporate. However, with advection fog, the key factor is that the air remains moist and relatively stable due to the continuous inflow of warm air. As such, even when the sun is shining, the cooling effect of the underlying surface (like cold water or land) and the ongoing moisture supply from the warm air prevent the fog from dissipating.

Therefore, the sun alone does not effectively burn off advection fog because the conditions that created the fog (the cool surface and moist air) continue to exist. For advection fog to dissipate, a change in temperature or moisture levels is needed, which is why stating that it cannot be burned off by the sun is accurate.
