1. Introduction It has for some time been widely accepted that in order to provide a realistic simulation of the climate of the middle atmosphere, it is necessary to represent the angular momentum transfer and resulting torque exerted within the middle atmosphere by internal gravity waves propagating up from the troposphere (see, e.g., McLandress 1998 ). Models without a representation of this process suffer from the so-called cold pole problem, namely a severe negative temperature bias in the

1. Introduction At scales appropriate for internal gravity waves, Eulerian spectra of temperature and horizontal velocity perturbations in the ocean and middle atmosphere exhibit nearly universal shapes ( Garrett and Munk 1975 ; Gargett et al. 1981 ; VanZandt 1982 ; Smith et al. 1987 ). At large vertical wavenumbers m , the average power spectral density (PSD) of horizontal Eulerian wind fluctuations in the atmosphere conforms to the power law E u ( m ) = αN   2 m −3 , where N is the

1. Introduction The determination of temperatures from Rayleigh-scattering measurements is an important remote sensing technique for temperature determination, particularly in the middle atmosphere, which is optically thin to visible light. This technique is used by Rayleigh-scatter lidar systems to retrieve temperature from photocount height profiles above the region of aerosol scattering (approximately 25 to 30 km). The retrieval of temperature from the photocount measurement is possible by

, response of the atmosphere to external forcing, and other topics for which it is advantageous to minimize differences in dynamical evolution. Another is that comparisons between model simulations and observations are facilitated when the same temporal variability is present in both. However, constraining some of the model fields in the lower or middle atmosphere does not guarantee that the simulation will closely match the dynamical observations in the upper atmosphere.
