Abstract
We investigate the effect of stratification by gravity on the propagation of linear magnetohydrodynamic (MHD) waves along a magnetic flux tube. For a quiescent environment linear wave propagation is governed by a Klein-Gordon equation. We consider the presence of a background flow in the tube and show the response to various atmospheric footpoint drivers. We solve for three drivers corresponding to a monochromatic source, a delta-function pulse and a sinusoidal pulse. This work is motivated by the vast amount of recent observational evidence supporting the existence of waves and flows in solar MHD waveguides.
