Advection of warm moist air over a cooler surface, such as water, causes fog.


1. The transfer of a property of the atmosphere, such as heat, cold, or humidity, by the horizontal movement of an air mass: Today's temperatures were higher due to the advection of warm air into the region.
2. The rate of change of an atmospheric property caused by the horizontal movement of air.
3. The horizontal movement of water, as in an ocean current.
