DOPPLER-SPREAD PARAMETERIZATION OF GRAVITY-WAVE MOMENTUM DEPOSITION IN THE MIDDLE ATMOSPHERE .2. BROAD AND QUASI-MONOCHROMATIC SPECTRA, ANDIMPLEMENTATION

This paper extends the parameterization that is developed in its compa nion paper, Part 1. It first discusses the input vertical-wavenumber s pectrum of the broad background of gravity waves that Part 1 is design ed to treat. It then employs one moder spectral form to summarize and illustrate the steps necessary for implementation of the parameterizat ion. Finally, it describes amendments that would be required when quas i monochromatic waves are to be included, and it specializes those ame ndments to the specific case of orographically generated waves.
