Planetary waves in rotating ionosphere

Plasma Physics Reports, 2008
The problem of propagation of ultralong planetary waves in the Earth’s upper atmosphere is considered. A new exact solution to the MHD equations for the ionosphere is obtained in spherical coordinates with allowance for the geomagnetic field and Earth’s rotation.

Modeling of the planetary structure of the ionosphere and the protonosphere coupling

pure and applied geophysics, 1988
A planetary model of the ionosphere and the protonosphere coupling is described. The system of three-dimensional nonstationary modeling equations of continuity and motion for the ions O+ and H+ is presented. Some numerical results of model calculations are compared with the experimental data.

Persistence of Planetary Waves in the Lower Ionosphere

Studia Geophysica et Geodaetica, 2003
The transient planetary waves in the atmosphere and ionosphere seem to occur in the form of bursts of a couple of waves with limited persistence. To study persistence of planetary wave events in the lower ionosphere, data from two radio paths from Central Europe are used, Luxembourg – Panska Ves (f = 6.09 MHz, f eq = 2.1-2.2 MHz) and Deutschlandfunk ...

On the planetary ionospheric vortex electric fields

Advances in Space Research, 2008
Abstract The paper presents a physical mechanism of large-scale vortex electric field generation in the ionospheric E- and F-layers. It shows that the planetary-scale, synoptic short-period (from several second to several hours) and fast processes (with propagation velocity higher than 1 km/s) produce a planetary-scale internal vortex electric field.

Planetary Waves in the Ionosphere

1998
Abstract : The objectives of this grant are to delineate and to better understand oscillations in ionospheric structure which occur at planetary-wave periods (i.e., 2-10 days). Effort has concentrated on analyses of about 30 years' of archived ionosonde data from a global array of stations, and some satellite-based measurements of total electron ...

Traveling planetary scale waves in the ionosphere

Journal of Atmospheric and Terrestrial Physics, 1975
Abstract From an analysis of long distance received daytime VLF phase data over three transmission paths spanning a total of 160° of longitude, and from lower stratospheric radiance data from the SIRS instrument on the Nimbus IV weather satellite, traveling planetary scale waves are shown to exist at about 70 km for the 1970/1971 winter.
