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 [PDF]

open access: possiblepure 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.

Current Systems in Planetary Magnetospheres and Ionospheres

Space Science Reviews, 2010
The interaction of planets with the solar wind produces a diversity of current systems, yet these can be classified into only a few different types, which include ionospheric currents, currents carried by magnetospheric boundaries like the magnetopause or ionopause, magnetotail currents, and currents flowing inside the magnetospheres, like ring ...

Planetary Ionospheres and Magnetospheres

2008
We begin this chapter with a detailed review of the ionization and recombination processes in a planetary ionosphere, as exemplified by the ionosphere we know the most about, that of the Earth. We then extend the discussion to the ionospheres of Mars and Venus, and examine atmospheric loss mechanisms.

Planetary Waves in the Ionosphere [PDF]

open access: possible, 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.

Planetary wave effect on ionospheric absorption

Journal of Atmospheric and Solar-Terrestrial Physics, 1998
Abstract A relationship is examined between quasi-periodic fluctuations in absorption data at ionospheric altitudes and wave perturbations in wind data at tropospheric, stratospheric and lower mesospheric heights at Indian latitudes. The spectral analyses using Maximum Entropy Method (MEM) reveal almost the same band of periodicities in both the ...
