The critical layer theory for gravity wave filtering is applied to an extended set of nightglow measurements obtained over a 3-mo period during May-July 1988 from a high-altitude site at the Mountain Research Station near Nederland Colorado, to study the effects of middle atmospheric winds on the propagation of short-period gravity waves. The measurements show almost total agreement between the observed and the permitted wave azimuths and speeds. It is inferred that the flow of wave energy into the upper atmosphere can be significantly modified by the background winds. It is suggested that middle atmospheric winds can play an important role in determining the flux and the azimuthal distribution of short-period waves reaching the upper atmosphere.
