Advection fog requires what environmental factor to form?

Advection fog forms when warm, moist air moves over a cooler surface, which causes the air temperature to drop and the moisture to condense into tiny droplets. The crucial environmental factor that facilitates the full formation of advection fog is the presence of strong wind conditions.

This is because strong winds contribute to the movement of warm, moist air from one location to another, allowing it to come in contact with the colder surface that leads to the cooling of the air. As the air cools sufficiently, it reaches the dew point, where the water vapor condenses, leading to fog formation. Therefore, without the wind to transport the warm moist air, advection fog would not develop effectively.

While cool temperatures, calm warm air, and visible moisture are all relevant to weather conditions, they do not specifically define the mechanism through which advection fog is primarily formed; rather, they contribute to other types of fog or weather phenomena.
