The Saturation of Gravity Waves in the Middle Atmosphere. Part I: Critique of Linear-Instability Theory COLIN O. HINESArecibo Observatory, Arecibo, Puerto Rico(Manuscript received 28 May 1990, in final form 21 December 1990)ABSTRACT The irregular winds of the middle atmosphere are commonly attributed to an upwardly propagating systemof atmospheric gravity waves. Their one-dimensional (in vertical wavenumber m) power spectrum has beenreported to exhibit a nearly universal

the first results from multiyear integrations of a troposphere–stratosphere configuration of the UM and document, in particular, its simulation of the middle atmosphere. The model configuration is similar to the global atmosphere version used in climate studies by the Hadley Centre (e.g., Mitchell et al. 1995 ) but with an extended vertical domain and increased vertical resolution near and above the tropopause. It has been developed for studying stratospheric processes and their role in climate

1. Introduction The semiannual oscillation (SAO) in zonal wind is the dominant mode of seasonal variability in the tropical middle atmosphere between the middle stratosphere and the upper mesosphere. The current picture of the SAO is constructed from combining various historical and more recent sets of in situ and remote observations. Rocket wind measurements (e.g., Hirota 1980 ; Garcia et al. 1997 ) and analyses of conventional meteorological data ( Baldwin and Gray 2005 ; Rienecker et al
