Gravity wave dynamics and effects in the middle atmosphere
TL;DR: In this article, a review of gravity wave sources and characteristics, the evolution of the gravity wave spectrum with altitude and with variations of wind and stability, the character and implications of observed climatologies, and the wave interaction and instability processes that constrain wave amplitudes and spectral shape are discussed.

Propagation characteristics of nighttime mesospheric and thermospheric waves observed by optical mesosphere thermosphere imagers at middle and low latitudes
TL;DR: In this paper, the authors review measurements of nighttime atmospheric/ionospheric waves in the upper atmosphere in Japan, Indonesia, and Australia, using all-sky airglow imagers of optical mesosphere thermosphere imagers (OMTIs).

Observations of spectra of intensity fluctuations of the OH Meinel nightglow during ALOHA‐93
TL;DR: In this paper, the authors reported that the average frequency spectrum shows little evidence of significant power at periods below 5 minutes, the Brunt-Vaisala period, but during a single one hour observation period there is increasing power at moments below 3 minutes, indicating the presence of acoustic waves at mesopause altitudes.

Airglow response to vertically standing gravity waves
Colin O. Hines,David W. Tarasick +1 more
TL;DR: In this article, the authors suggest that the discrepancy results from failure of the common theoretical assumption that the relevant gravity waves are dominated by a single upgoing component: that, instead, there is an accompanying downgoing component of comparable magnitude, produced by reflection.

Trends of airglow imager observations near Adelaide, Australia
TL;DR: In this article, a nightglow imager and an airglow photometer were located near Adelaide, Australia and the data obtained on more than 50 clear nights revealed seasonal changes in the air glow intensities and temperatures as well as in the gravity wave activity.

Atmospheric tides between 80 km and 120 km
TL;DR: In this paper, the structure and variability of tides in the 80-120 km height region are reviewed and seasonal-latitudinal variations in the vertical structure of diurnal and semidiurnal winds between 70-100 km as measured by meteor and partial reflection drift radars, and tidal temperatures determined by incoherent scatter radars between 100 and 140 km.

Ducting of internal gravity waves on a stable layer with shear
TL;DR: In this article, a simple numerical model is used to study internal gravity waves ducted on a stable layer with wind shear, where ducted modes are confined to propagation cones nearly normal to the shear vector.
