, 2017 This chapter deals with the underlying mathematics of atmospheric waves. Gravity waves occur between any stable layers of fluids that differ in density. When the fluid boundary is disturbed, buoyancy forces try to restore the equilibrium.

The prospect of studying atmospheric gravity waves with balloon lidars [PDF]
, 2022 Long duration balloons are ideal platforms to study atmospheric gravity waves with remote sensing Rayleigh lidar instruments. Using a laser beam and receiving telescope, atmospheric density and temperature are sounded throughout the stratosphere and ...

Journal of Marine Science and Engineering, 2016 We study the atmospheric structure in response to the propagation of gravity waves under nonisothermal (nonzero vertical temperature gradient), wind-shear (nonzero vertical zonal/meridional wind speed gradients), and dissipative (nonzero molecular ...

Successfully Simulating Atmospheric Gravity Waves
Eos, 2020 These waves are key to moving energy from the troposphere to the thermosphere, but until now they haven’t been well described at high altitudes in computer models.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...

Mirages with atmospheric gravity waves [PDF]
, 1994 The temperature inversions that produce superior mirages are capable of supporting gravity (buoyancy) waves of very low frequency and long wavelength. This paper describes the optics of single mode gravity waves that propagate in a four-layer atmosphere.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Observational study of the atmospheric gravity waves in the lower solar atmosphere
Monthly Notices of the Royal Astronomical SocietyABSTRACT The solar chromosphere exhibits a variety of waves originating from the photosphere and deeper layers, causing oscillations at different heights with distinct frequencies. This study identifies and analyse atmospheric gravity waves (AGWs) and acoustic waves at various height pairs within the solar atmosphere utilizing H$\alpha$,
