Convectively Generated Gravity Waves in High Resolution Models of Tropical Dynamics

Journal of Advances in Modeling Earth Systems, 2018
We investigate numerical models that display the transition of global climate modeling from coarse grids, at which convection and gravity waves are still parameterized, toward finer resolutions, where both are treated explicitly.

A statistical study of gravity waves from radiosonde observations at Wuhan (30° N, 114° E) China [PDF]

Annales Geophysicae, 2005
Several works concerning the dynamical and thermal structures and inertial gravity wave activities in the troposphere and lower stratosphere (TLS) from the radiosonde observation have been reported before, but these works were concentrated on either ...

Simulation of non-hydrostatic gravity wave propagation in the upper atmosphere [PDF]

Annales Geophysicae, 2014
The high-frequency and small horizontal scale gravity waves may be reflected and ducted in non-hydrostatic simulations, but usually propagate vertically in hydrostatic models. To examine gravity wave propagation, a preliminary study has been conducted

The effect of extra dimensions on gravity wave bursts from cosmic string cusps

, 2010
We explore the kinematical effect of having extra dimensions on the gravity wave emission from cosmic strings. Additional dimensions both round off cusps, and reduce the probability of their formation.

First tomographic observations of gravity waves by the infrared limb imager GLORIA [PDF]

Atmospheric Chemistry and Physics, 2017
Atmospheric gravity waves are a major cause of uncertainty in atmosphere general circulation models. This uncertainty affects regional climate projections and seasonal weather predictions.

Techniques for studying gravity waves and turbulence: Horizontal, vertical and temporal resolution needed [PDF]

, 1983
One of the most important atmospheric measurements that is needed is a measure of the gravity-wave spectrum. The MST radar has been investigated as means to measure the temporal resolution required to determine gravity-wave oscillations.

Relic Gravity Waves from Braneworld Inflation [PDF]

, 2001
We discuss a scenario in which extra dimensional effects allow a scalar field with a steep potential to play the dual role of the inflaton as well as dark energy (quintessence).

Climatology of gravity wave activity during the West African Monsoon [PDF]

Annales Geophysicae, 2008
Gravity wave activity is analysed in the lower stratosphere using 6 year radiosonde data (2001–2006) above two meteorological stations in the West African tropical region such as Niamey (13.47° N; 2.16° E) and Ouagadougou (12.35° N; 1.51 ...
