Propagation paths and source distributions of resolved gravity waves in ECMWF-IFS analysis fields around the southern polar night jet [PDF]
In the southern winter polar stratosphere, the distribution of gravity wave momentum flux in many state-of-the-art climate simulations is inconsistent with long-time satellite and superpressure balloon observations around 60∘ S.

Gravity waves in the Sun [PDF]
We present numerical simulations of penetrative convection and gravity wave excitation in the Sun. Gravity waves are self-consistently generated by a convective zone overlying a radiative interior. We produce power spectra for gravity waves in the radiative region as well as estimates for the energy flux of gravity waves below the convection zone.

Parasitic Capillary Waves on Small-Amplitude Gravity Waves with a Linear Shear Current
This paper describes a numerical investigation of ripples generated on the front face of deep-water gravity waves progressing on a vertically sheared current with the linearly changing horizontal velocity distribution, namely parasitic capillary waves ...

Shallow flows of generalised Newtonian fluids on an inclined plane [PDF]
We derive a general evolution equation for a shallow layer of a generalised Newtonian fluid undergoing two-dimensional gravity-driven flow on an inclined plane.

Gravity waves in three dimensions [PDF]
We find the explicit forms of the anti-de Sitter plane, anti-de Sitter spherical, and pp waves that solve both the linearized and exact field equations of the most general higher derivative gravity theory in three dimensions. As a sub-class, we work out the six derivative theory and the critical version of it where the masses of the two spin-2 ...

Birkhoff Normal form for Gravity Water Waves [PDF]
We consider the gravity water waves system with a one-dimensional periodic interface in infinite depth, and present the proof of the rigorous reduction of these equations to their cubic Birkhoff normal form (Berti et al.

The contour-advective semi-Lagrangian hybrid algorithm approach to weather forecasting and freely propagating inertia-gravity waves in the shallow-water system [PDF]
This thesis is aimed at extending the spherical barotropic contour-advective semi-Lagrangian (CASL) Algorithm, written in 1996 by David Dritschel and Maarten Ambaum, to more complex test cases within the shallow-water context.

The ocean's interior is filled with waves that can only exist because the ocean is vertically stratified in temperature and salinity. Like waves at the ocean surface, internal waves are restored by gravity. These internal gravity waves are generated by wind, tides, and low-frequency flows.

Heating and cooling of the thermosphere by internal gravity waves [PDF]
For the first time, estimates of heating and cooling in the upper thermosphere due to dissipating and breaking gravity waves ( GWs) of tropospheric origin have been obtained with a comprehensive general circulation model ( GCM).

La Soufriere Volcanic Eruptions Launched Gravity Waves Into Space [PDF]
Atmospheric gravity waves can be excited by explosive volcanic eruptions and may reach Earth's upper atmosphere. In this study, we report on mesoscale concentric gravity waves observed in the mesopause airglow layer following the La Soufriere volcano ...
