High Frequency Gravity Waves Observed in OH airglow at Starfire Optical Range, NM: Seasonal Variations in Momentum Flux
TL;DR: In this paper, the seasonal variation of the vertical fluxes of horizontal momentum carried by high frequency Atmospheric Gravity Waves (AGWs) was estimated using lidar measurements at Starfire Optical Range, New Mexico (35°N, 107°W).

Statistical characteristics of gravity wave activities observed by an OH airglow imager at Xinglong, in northern China
TL;DR: In this paper, an all-sky airglow imager (ASAI) was installed at Xinglong, in northern China (40.2° N, 117.4° E) in November 2009 to study the morphology of atmospheric gravity waves (AGWs) in the mesosphere and lower thermosphere (MLT) region.

Extension of the MSIS Thermosphere Model into the middle and lower atmosphere
TL;DR: In this paper, the MSIS-86 empirical model has been extended into the mesosphere and lower atmosphere to provide a single analytic model for calculating temperature and density profiles representative of the climatological average for various geophysical conditions.

TL;DR: In this article, the HWM90 thermospheric wind model has been revised in the lower thermosphere and extended into the mesosphere, stratosphere and lower atmosphere to provide a single analytic model for calculating zonal and meridional wind profiles representative of the climatological average for various geophysical conditions.

Gravity wave activity in the lower atmosphere: Seasonal and latitudinal variations
Simon J. Allen,Robert A. Vincent +1 more
TL;DR: A climatology of gravity wave activity in the lower atmosphere based on high-resolution radiosonde measurements provided by the Australian Bureau of Meteorology is presented in this article, where the vertical wavenumber power spectra of normalized temperature fluctuations are calculated within both the troposphere and the lower stratosphere and compared with the predictions of current gravity wave saturation theories.

Interpretations of observed climatological patterns in stratospheric gravity wave variance
TL;DR: In this paper, a linear model of gravity wave propagation is applied to investigate the underlying causes of some of the observed patterns, and the model shows that this coupling can give rise to geographical, seasonal, and vertical variations in gravity wave observations without any variations in the spectrum or amplitude of the sources in the troposphere.

A Climatology of Gravity Wave Motions in the Mesopause Region at Adelaide, Australia
TL;DR: In this paper, a statistical study of gravity wave motions in the mesosphere and lower thermosphere measured with a MF partial reflection radar located at Buckland Park new Adelaide (35°S, 138°E) in the period November 1933 to December 1984 is presented.
