A Hydromagnetic Theory of Geomagnetic Storms

Geophysical Journal International, 1962
Summary The following hydromagnetic theory of geomagnetic storms is outlined: (a) A solar ion stream envelopes the geomagnetic cavity exerting radial pressure and tangential frictional drag. The former creates an O-type hydromagnetic wave, the latter E-type (twist) waves. The frictional effect may also scatter 104 eV electrons into the cavity

Forecast of recurrent geomagnetic storms

Advances in Space Research, 2011
Abstract Long-term forecast of space weather allows in achieving a longer lead time for taking the necessary precautions against disturbances. Hence, there is a need for long-term forecasting of space weather. We studied the possibility for a long-term forecast of recurrent geomagnetic storms.

Weather reacting to geomagnetic storms

Advances in Space Research, 2004
Abstract In the first 15 years of the Space Age satellite position measurements derived from visual and photographic observations helped to determine the decay rate of satellites, by means of which the first models of the upper-atmosphere have been calculated.

On F2 response to geomagnetic storm

Acta Geodaetica et Geophysica Hungarica, 2003
The interaction of solar wind with earth’s magnetic field leads to a number of modifications of the F region global structure. Furthermore, the absorption of solar wind energy has the same phase all over the globe throughout the year. All these imply that there could be simultaneity in UT in global response of some F2 parameters to geomagnetic storms ...

Solar antecedents of geomagnetic storms

1997
Geomagnetic storms occur when solar wind with unusual characteristics touches the Earth's magnetosphere, but their ultimate origins lie in the structure and dynamics of the solar atmosphere. We observe this atmosphere above the solar limb with coronagraphs, and generally across the whole visible hemisphere at radio and XUV wavelengths.
