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.

[Latin advectiō, advectiōn-, act of conveying, from advectus, past participle of advehere, to carry to : ad-, ad- + vehere, to carry; see wegh- in Indo-European roots.]

ad·vec′tive adj.


(General Physics) the transference of heat energy in a horizontal stream of gas, esp of air
[C20: from Latin advectiō conveyance, from advehere, from ad- to + vehere to carry]


(ædˈvɛk ʃən)

1. a shift in temperature, humidity, or the like resulting from horizontal movement of an air mass (disting. from convection).
2. the horizontal flow of air, water, etc.
[1905–10; < Latin advectiō=advec-, variant s. of advehere to convey (ad- ad- + vehere to carry) + -tiō -tion]
