Cold air is heated up when it comes into contact with warm ground. Heat is transferred from warm water to the cold air by advection.
A type of fog that results from air being cooled following its horizontal movement. This could result from either cold air passing across a warmer sea or water surface while mixing with warm air prevailing there, or the air becoming chilled by coming into contact and mixing with cold air associated with a cold surface.
