A numerical study of the propagation characteristics of the first symmetric or (1,1) tidal mode is presented for the case of a background atmosphere of mean winds, meridional temperature gradients, and mechanical and thermal dissipation. The primary effects of dissipation are found to be the production of an amplitude peak in the 90-km vicinity, an increase in the vertical wavelength with height from 80-100 km, and a broadening or spreading of the tidal oscillation to higher latitudes. The present results are consistent with the behavior of the diurnal tide as noted by partial reflection, meteor, and incoherent scatter radars. The presence of mean winds during solstice conditions manifests itself by the introduction of asymmetries about the equator in amplitude and phase.
