The correct conditions for fog formation are relative humidity, vertical air currents, very light or calm winds, air temperature cooled to dew point, and stable air. Strong winds are not typically conducive to fog formation.
Stable Air: Stable air conditions, where the air near the surface is cooler than the air above, can promote the cooling of the air to its dew point and the formation of fog.
Therefore, the correct conditions for fog formation are relative humidity, vertical air currents, very light or calm winds, air temperature cooled to dew point, and stable air. Strong winds are not typically conducive to fog formation.
