Advection

The transport of an additive quantity – heat, internal energy, an arbitrary chemical element, electrical charges – by a moving fluid, no matter what the origin of the movement, gravitational instability or an impetus given by some force. In oceanography, for example, advection refers in particular to the horizontal transport of certain properties by the fluids considered, including transport by wind or by the currents: advection of water vapour, heat, salinity, etc.
