Explore: Advection

In the fields of physics, engineering, and earth sciences, advection is the transport of a substance or quantity by bulk motion of a fluid. The properties

convection is a similar phenomenon in granular material instead of fluids. Advection is the transport of any substance or quantity (such as heat) through fluid

"puff up" into a torus or some other three-dimensional solution like an Advection Dominated Accretion Flow (ADAF). The ADAF solutions usually require that

of terrain with the absence of wind. Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled. It is common as

of moisture advection are often co-located with regions of warm advection. Using the classical definition of advection, moisture advection is defined as:

partial differential equation that combines the diffusion and convection (advection) equations. It describes physical phenomena where particles, energy, or

continuous environment. It is defined to be the ratio of the rate of advection of a physical quantity by the flow to the rate of diffusion of the same

Positive vorticity advection, or PVA, is the result of more cyclonic values of vorticity advecting into lower values of vorticity. It is more generally
