Hydromagnetic theory of geomagnetic storms
Journal of Geophysical Research, 1959A hydromagnetic theory is presented which explains the average characteristics of geomagnetic storms. The magnetic storm is caused by a sudden increase in the intensity of the solar wind. Stresses are then set up in the geomagnetic field by the solar plasma impinging upon the geomagnetic field and becoming trapped in it.

Tutorial on geomagnetic storms and substorms
IEEE Transactions on Plasma Science, 2000Geomagnetic storms have been studied for more than a century and substorms for nearly four decades. The space era which began in the late 1950s has ushered new discoveries and given new practical importance to this scientific discipline as we continue to amass technological assets in space.

A Hydromagnetic Theory of Geomagnetic Storms
Geophysical Journal International, 1962Summary 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, 2011Abstract 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.

Fractal dynamics of geomagnetic storms
Arabian Journal of Geosciences, 2011We explore fluctuations of the horizontal component of the Earth’s magnetic field to identify scaling behaviour of the temporal variability in geomagnetic data recorded by the Intermagnet observatories during the solar cycle 23 (years 1996 to 2005). In this work, we use the remarkable ability of scaling wavelet exponents to highlight the singularities ...

Weather reacting to geomagnetic storms
Advances in Space Research, 2004Abstract 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.

The Evolution Characteristics of Geomagnetic Disturbances During Geomagnetic Storm
Chinese Journal of Geophysics, 2007AbstractWith the data of the geomagnetic meridian observatories in China, 25 geomagnetic storms in the period of 1997 to 1999 have been analyzed by using three kinds of methods which are the method of Natural Orthogonal Components (NOC), Correlation analysis and Fourier analysis. Three steps have been adopted to decompose the storm‐time variation (Dst)

On F2 response to geomagnetic storm
Acta Geodaetica et Geophysica Hungarica, 2003The 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 ...

The Theory of Geomagnetic Storms and Auroras
IETE Journal of Research, 1966ABSTRACTThe importance of geomagnetic storms in ionospheric radio propagation is stressed and our understanding of storms and auroras is briefly reviewed. Two main problems remaining are (a) origin of auroral electrons, and (b) origin of the ring current.
