Journal ArticleDOI

A. E. Hedin,E. L. Fleming,A. H. Manson,F. J. Schmidlin,Susan K. Avery,R.R. Clark,Steven J. Franke,Grahame J. Fraser,Toshitaka Tsuda,François Vial,Robert A. Vincent +10 more
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.
Journal ArticleDOI
On modeling migrating solar tides
TL;DR: In this paper, the seasonal variability of the migrating solar diurnal harmonic as it propagates into the mesosphere and lower thermosphere is examined, using a two-dimensional linearized model of global-scale atmospheric waves.
Journal ArticleDOI
On tidal variability induced by nonlinear interaction with planetary waves
H. Teitelbaum,François Vial +1 more
TL;DR: In this article, it was shown that the amplitude of the induced fluid velocity in the direction of wave propagation compared to the wave propagation velocity is a strong indicator of nonlinear interactions between tides and planetary waves having periods corresponding to those of observed tidal amplitude modulations.
Journal ArticleDOI
Estimation of Gravity Wave Momentum Flux and Phase Speeds from Quasi-Lagrangian Stratospheric Balloon Flights. Part II: Results from the Vorcore Campaign in Antarctica
TL;DR: In this paper, the authors investigated the stratospheric gravity wave field in the Southern Hemisphere by analyzing observations collected by 27 long-duration balloons that flew between September 2005 and February 2006 over Antarctica and the Southern Ocean.
Journal ArticleDOI
Climatologies of semi-diurnal and diurnal tides in the middle atmosphere (70–110 km) at middle latitudes (40–55°)
A. H. Manson,Chris Meek,H. Teitelbaum,François Vial,R. Schminder,Dierk Kürschner,M. J. Smith,Grahame J. Fraser,R.R. Clark +8 more
TL;DR: In this paper, the radars utilized are meteor (2), medium-frequency (2) and new low frequency (1) systems: analysis techniques have been exhaustively studied internally and comparatively and are not thought to affect the results.
