For a horizontally homogeneous atmosphere with vertical wind shear, vortex lines and Theta-E surfaces are initially horizontal (EPV=0). Since EPV is conserved, vortex lines remain on the original theta-E surfaces if they are subsequently tilted up or down…. . Advection is the transfer of a property of the air by the wind.
