Tropospheric - Stratospheric Tidal Investigations. Diurnal and Semidiurnal Wind Oscillations in the Stratosphere.

Abstract

Amplitudes and phases of diurnal and semidiurnal wind oscillations derived from 21 series of meteorological rocket launchings in the years 1965-74 are presented and discussed for different latitude regions in terms of the properties of diurnal and semidiurnal Hough modes of solar tidal oscillation. The investigation attempts to identify the likely ranges of modes (m,s,n),m = 1,2 which are compatible with excitation by ozone and water vapour heating and the observational results. Significant contributions from non-migrating modes (s not = m) and from non-tidal variations are in evidence for particular latitude regions. A summary is given of a number of tentative conclusions that are reached on the basis of the available data. (Author)
