• Classical theory of atmospheric tide predicts the confinement of propagating diurnal tide to lower latitudes equatorward of 30° latitude for which diurnal frequency exceeds the local Coriolis frequency. Observations so far averaged over appropriate periods, however, suggest the pervasion of propagating tide at meteor heights especially in wintertime in view of vertical phase structure. These might possibly be interpreted by the numerical modeling as the penetration of non-migrating higher zonal wave number tides which can be propagating in the counter-stream Doppler effect of the background mean zonal wind.
