Abstract:
Though there is an enhancement of semidiurnal tide during the sudden stratospheric warming events, it is not known whether the enhancement is due to migrating tide or nonmigrating tide. If it is due to nonmigrating tides, how and where are they generated? The results from this paper show that though migrating semidiurnal tide is so dominant at stratosphere and lower mesospheric heights, its amplitude decreases at heights around 100 km, where nonmigrating tidal amplitudes become significant. This suggests that the nonlinear interaction between PW and tides occurs at upper mesospheric heights and they contribute significantly to the low‐latitude ionospheric variabilities, as migrating tide.
