WebMay 14, 2024 · Advection fog usually occurs when the atmosphere is very stable so that moist (humid) air near the surface does not mix vertically with an overlying layer of drier air. The advection fog forms as warm and moist air moves horizontally along the cooler surface and the air near the surface is cooled to its dew point . Fog can form in a number of ways, depending on how the cooling that caused the condensation occurred. Radiation fog is formed by the cooling of land after sunset by infrared thermal radiation in calm conditions with a clear sky.
