Abstract

Four and a half years of data from a meteor radar based at Sheffield, UK, representing measurements of neutral wind velocity in the meteor region above 53°27'N, 3°53'W, are analysed to produce climatologies of both longer-period (2-30 days) neutral-wind oscillations (e.g. planetary waves) and longer-period variability in tidal amplitude measurements using running (dynamic) periodograms. The observed burst-like nature of longer-period oscillations and migration of period are discussed in the light of current planetary-wave theory. Evidence for the cyclical modulation of tidal amplitude with periods similar to those of planetary waves is also presented and its possible origin discussed.
