[PEM09-04] Observations of MLT dynamics using meteor radars and meteor radar networks
Keywords:meteor radar, horizontally resolved winds, planetary waves, atmospheric tides and gravity waves, vertical coupling
To investigate the change in propagation characteristics of gravity waves and tides in the upper mesosphere/ lower thermosphere (MLT) during this unusual zonal wind reversal in winter 2015/16 we use data from a meteor radar network in Scandinavia. With this network we are able to apply tomographic wind field analysis obtaining horizontally resolved wind fields and horizontal wavelength spectra. Further, we are able to assess the spatial and temporal day-to-day variability of tides.
