Periods of planetary waves in geomagnetic variations [PDF]

open access: yesAnnales Geophysicae, 1995
Periods of planetary waves, especially the 10- and 16-day waves, were found in Fourier analyses of 10-year geomagnetic time series from two mid-latitude stations in the northern hemisphere.

Observing System Simulation Experiment to Reproduce Kelvin Wave in the Venus Atmosphere

open access: yesAtmosphere, 2020
Planetary-scale 4-day Kelvin-type waves at the cloud top of the Venus atmosphere have been reported from the 1980s, and their significance for atmospheric dynamics has been pointed out.

Stratospheric tropical warming event and its impact on the polar and tropical troposphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Stratosphere–troposphere coupling is investigated in relation to middle atmospheric subtropical jet (MASTJ) variations in boreal winter. An exceptional strengthening of the MASTJ occurred in association with a sudden equatorward shift of the ...

A dynamics-based separation of deep and shallow stratospheric circulation branches [PDF]

open access: yesAtmospheric Chemistry and Physics
The wave-driven Brewer–Dobson circulation plays a crucial role in determining the transport of trace gases and aerosols in the stratosphere. We examine the structure of the circulation based on reanalysis data (ERA5, ERA-Interim, MERRA2, and JRA55) and ...

Features of 3–7-day planetary-wave-type oscillations in F-layer vertical drift and equatorial spread F observed over two low-latitude stations in China [PDF]

open access: yesAnnales Geophysicae, 2017
Recent studies on the equatorial atmosphere–ionosphere coupling system have shown that planetary-wave-type oscillations, as an important seeding mechanism for equatorial spread F (ESF), play an important role in ESF irregularity development and its ...

Assessing the role of planetary and gravity waves in the vertical structure of ozone over midlatitudinal Europe [PDF]

open access: yesAnnales Geophysicae, 2019
Planetary and gravity waves play an important role in the dynamics of the atmosphere. They are present in the atmospheric distribution of temperature, wind, and ozone content.

Traveling planetary‐scale Rossby waves in the winter stratosphere: The role of tropospheric baroclinic instability

open access: yesGeophysical Research Letters, 2012
The Southern Hemisphere winter stratosphere exhibits prominent traveling planetary‐scale Rossby waves, which generally are not able to induce Stratospheric Sudden Warmings. A series of runs of a simplified general circulation model is presented, aimed at

Breaking planetary waves in the stratosphere

open access: yesNature, 1983
Satellite-borne IR radiometers are turning the Earth's stratosphere into one of the best available outdoor laboratories for observing the large-scale dynamics of a rotating, heterogeneous fluid under gravity. New insight is being gained not only into stratospheric dynamics as such, with its implications for pollutant behaviour and the ozone layer, but ...

Infrasound From Large Earthquakes Recorded on a Network of Balloons in the Stratosphere

open access: yesGeophysical Research Letters, 2022
The ground movements induced by seismic waves create acoustic waves propagating upward in the atmosphere, thus providing a practical solution to perform remote sensing of planetary interiors.

Vertical motion of ionization induced by the linear interaction of tides with planetary waves [PDF]

open access: yesAnnales Geophysicae, 2003
Experimental findings have shown that travelling planetary waves modulate the occurrence of mid-latitude sporadic-E-layers. Using a simple quantitative model, we analyse the effects of the linear interaction between tides and planetary waves on ion
