Fog Formation
Fog, in essence, is a cloud that forms at ground level. When warm, moist air cools near the ground, water vapor condenses into tiny water droplets, creating a dense haze. This usually happens on clear, calm nights, when the ground radiates heat into the atmosphere, cooling the air near the surface.
