Atmospheric gravity waves have been a subject of intense research activity in recent years
because of their myriad effects and their major contributions to atmospheric circulation …

This paper provides a review of recent advances in our understanding of gravity wave
saturation in the middle atmosphere. A brief discussion of those studies leading to the …

Dynamical and convective instabilities are two mechanisms that contribute significantly to
the dissipation of larger‐scale motions and the generation of turbulence in the middle …

Radiosonde observations made at Cocos Islands (12° S, 97° E) in the Indian Ocean
between September 1992 and June 1998 are used to study seasonal and interannual …

The book summarizes international progress over the last few decades in upper atmosphere
airglow research. Measurement methods, theoretical concepts and empirical models of a …

This study examines the properties of inertia–gravity waves observed in the lower
stratosphere over Macquarie Island, how these properties vary with season, and the likely …

The GISS global climate model (Hansen et al.) has been extended to include the middle
atmosphere up to an altitude of approximately 85 km. The model has the full array of …

Fluctuations in vertical profiles of atmospheric temperature and horizontal wind in the 20–60
km altitude range have been isolated from meteorological rocket measurements during …

The nightly and seasonal variations in gravity wave activity in the mesopause region are
examined by analyzing 60 nights of Na lidar observations obtained during a 5‐year period …

We review measurements of nighttime atmospheric/ionospheric waves in the upper
atmosphere in Japan, Indonesia, and Australia, using all-sky airglow imagers of optical …
