PPT-SO254 - Advection

What is advection Advection is the transfer of a property of the air by the wind There are many things that can be advected temperature vorticity relative and planetary momentum moisture. Contaminant Transport. Modelling. Contaminant Transport in Porous Media. Advection. Advection causes translation of the solute field by moving the solute with the flow velocity.
