ResumoTidal variability in the middle atmosphere during September 2019 Southern hemisphere minor sudden stratospheric warming (SSW) is investigated utilizing ground-based meteor radar wind observations from the equatorial, extratropical, middle, and high latitude stations and reanalysis dataset. The poleward warming moves from the mesosphere to the stratosphere before the onset of SSW. The diurnal and semidiurnal tides at individual observational sites do not exhibit any significant response to the warming event, but a notable response in some specific zonal wavenumber components, i. e., DW1 (migrating diurnal tide), DE3 (nonmigrating eastward wavenumber 3 diurnal tide), and SW2 (migrating semidiurnal tide) is found in the global reanalysis dataset. The DW1 enhances during the post-warming days in the mesosphere and lower thermosphere (MLT) possibly due to increased water vapor at all the meteor radar observing locations. The DE3 amplitude at mid and high latitude shows a contrasting behavior with respect to the low latitude in the MLT i.e., a decrease in the amplitude at mid and high latitudes concurrent with an increase at low latitudes during the postwarming phase. SSW-related convective activity variability may explain the observed DE3 variability. In general, the SW2 amplitude diminishes during the post-warming interval in the MLT, possibly due to the weakening and subsequent reversal of the zonal wind and reduction in ozone concentration. The present study entails the disparate responses between the local tidal dynamics at individual observational locations and the global tidal variability in connection with the SSW.
