The nonlinear effects on the characteristics of gravity wave packets: dispersion and polarization relations [PDF]

open access: yesAnnales Geophysicae, 2000
By analyzing the results of the numerical simulations of nonlinear propagation of three Gaussian gravity-wave packets in isothermal atmosphere individually, the nonlinear effects on the characteristics of gravity waves are studied quantitatively.

Satellite Observations of Stratospheric Gravity Waves Associated With the Intensification of Tropical Cyclones

open access: yesGeophysical Research Letters, 2018
Forecasting the intensity of tropical cyclones is a challenging problem. Rapid intensification is often preceded by the formation of “hot towers” near the eyewall.

The Impact of Mesoscale Processes on the Atmospheric Circulation of Mars [PDF]

open access: yes, 2010
The study of the modern martian atmosphere is (1) a key to the climate of Mars’s past; (2) useful for comparison with other terrestrial planets such as the Earth; and (3) can support hazard analysis and weather forecasting for future exploration and ...

Excitation of acoustic-gravity waves in an isothermal atmosphere [PDF]

open access: yesTellus, 1971
The excitation of acoustic-gravity waves in an isothermal atmosphere is considered in this paper. It is shown that the excitation due to mass production, momentum production and heat production can be discussed by examining the same differential equation. The sources are assumed to be extended and vary both in time and in space.

Rolls of the internal gravity waves in the Earth's atmosphere [PDF]

open access: yesAnnales Geophysicae, 2014
Abstract. The effect of the wind shear on the roll structures of nonlinear internal gravity waves (IGWs) in the Earth's atmosphere with the finite vertical temperature gradients is investigated. A closed system of equations is derived for the nonlinear dynamics of the IGWs in the presence of temperature gradients and sheared wind.

Using sub-limb observations to measure gravity waves excited by convection

open access: yesnpj Microgravity, 2023
Convective gravity waves are a major driver of atmospheric circulation, including the stratospheric and mesospheric quasi-biennial oscillation (QBO) and the Brewer–Dobson circulation.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Hunting for gravity waves in non-orographic winter storms using 3+ years of regional surface air pressure network and radar observations [PDF]

open access: yesAtmospheric Chemistry and Physics
Atmospheric gravity waves (i.e., buoyancy waves) can occur within stable layers when vertical oscillations are triggered by localized heating, flow over terrain, or imbalances in upper-level flow.
