Definition of the noun advection

What does advection mean as a name of something?

noun - plural: advections

  1. (meteorology) the horizontal transfer of heat or other atmospheric properties

Alternative definition of the noun advection


  1. The horizontal movement of a body of atmosphere (or other fluid) along with a concomitant transport of its temperature, humidity etc.
  2. The transport of a scalar by bulk fluid motion.


Advection: In physics, engineering, and earth sciences, advection is a transport mechanism of a substance or conserved property by a fluid due to the fluid's bulk motion. An example of advection is the transport of pollutants or silt in a river by bulk water flow downstream. Another commonly advected quantity is energy or enthalpy. Here the fluid may be any material that contains thermal energy, such as water or air. In general, any substance or conserved, extensive quantity can be advected by a fluid that can hold or contain the quantity or substance.
