The zonal mean circulation induced by the ultralong wave k=1 has been determined by a simple quasi-geostrophic model. The zonal mean tracer distribution dependence on phase differences between orographical and thermally forced waves is discussed. It is shown that the divergence of Q' Psi ' has a large influence on the Lagrangian mean vertical velocity. The divergence of Q' Psi ' shows large variations dependent on the phase of orographical and thermally forced waves mainly in the troposphere. The phase difference in the forcing of the wave k=1 between orography and surface temperature can change the induced Lagrangian mean vertical velocities and also the mean tracer transport.
