Gravity Waves in Planetary Atmospheres: Their Effects and Parameterization in Global Circulation Models

Atmosphere, 2019
The dynamical and thermodynamical importance of gravity waves was initially recognized in the atmosphere of Earth. Extensive studies over recent decades demonstrated that gravity waves exist in atmospheres of other planets, similarly play a significant ...

Observations of in-situ generated gravity waves during a stratospheric temperature enhancement (STE) event [PDF]

Atmospheric Chemistry and Physics, 2011
Evidence for in situ generated atmospheric gravity waves associated with a stratospheric temperature enhancement (STE) are presented. The signatures of two sets of gravity waves are observed by molecular-aerosol lidar in conjunction with the early ...

Atmospheric Gravity Waves: Processes and Parameterization [PDF]

Journal of the Atmospheric Sciences
Abstract Atmospheric predictability from subseasonal to seasonal time scales and climate variability are both influenced critically by gravity waves (GW). The quality of regional and global numerical models relies on thorough understanding of GW dynamics and its interplay with chemistry, precipitation, clouds, and climate across many scales.

Analytic solutions for Long's equation and its generalization [PDF]

Nonlinear Processes in Geophysics, 2017
Two-dimensional, steady-state, stratified, isothermal atmospheric flow over topography is governed by Long's equation. Numerical solutions of this equation were derived and used by several authors.

Acoustic gravity wave growth and damping in convecting plasma [PDF]

Annales Geophysicae, 1994
The propagation of acoustic gravity waves through steadily convecting plasma in the thermosphere has been analysed theoretically. The growth and damping rates of internal gravity waves due to the feedback effects of wave-modulated Joule heating and ...

Upward propagation of gravity waves and ionospheric perturbations triggered by the 2022 Hunga-Tonga volcanic eruption

Earth, Planets and Space, 2023
Using an atmosphere–ionosphere coupled model (GAIA), atmospheric and ionospheric perturbations triggered by the 2022 Hunga-Tonga volcanic eruption are studied.

Large-eddy simulation of an atmospheric bore and associated gravity wave effects on wind farm performance in the southern Great Plains [PDF]

Wind Energy Science
Gravity waves are a common occurrence in the atmosphere, with a variety of generation mechanisms. Their impact on wind farms has only recently gained attention, with most studies focused on wind farm-induced gravity waves.

Spectral variability in high frequency in sea level and atmospheric pressure on Buenos Aires Coast, Argentina

Brazilian Journal of Oceanography
There are some observational evidences which support that atmospheric gravity waves constitute an efficient forcing for meteorological tsunamis (meteotsunamis) along the coast of Buenos Aires, Argentina. Meteotsunamis and atmospheric gravity waves, which
