FIG. 3. Vertical wavenumber spectra in the meso phere (M), lowerstratosphere (S), and troposphere (F) from the 1U radar observations m October 1986. The zonal and meridional spectral curvesare indicated by (solid) and (dotted) lines, respectively. The modelsaturated gravity wave spectrum (Smith et al. 1987) is indicated bystraight lines, (dashed) for the troposphere and (dot-dashed) for themesosphere and lower stratosphere.
