advection

the transference of heat energy in a horizontal stream of gas, esp of air

advection

[‚ad′vek·shən]
(meteorology)
The process of transport of an atmospheric property solely by the mass motion of the atmosphere.
(oceanography)
The process of transport of water, or of an aqueous property, solely by the mass motion of the oceans, most typically via horizontal currents.

advection

A method of heat transfer by horizontal movement of air or fluid. Unlike convection, where heat transfer takes place because of vertical movement, here the horizontal movement is the cause. When cold air comes into contact with warm ground or water, it heats up because of advection.
