Bracing for the geomagnetic storms

IEEE Spectrum, 1990
As solar activity moves toward an 11 year peak, utility engineers are girding for the effects of massive magnetic disturbances. The nature of the geomagnetic disturbances is examined. The way in which geomagnetically induced current (GIC) affects power systems is explained.

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.

Fractal dynamics of geomagnetic storms

Arabian Journal of Geosciences, 2011
We 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 ...

Dynamics of the geomagnetic storm

Space Science Reviews, 1962
This paper is intended as a critical review of current ideas concerning the mechanisms responsible for the geomagnetic storm. The dynamical theory of the geomagnetic storm phenomenon is formulated as a problem in elasticity. The observed variations in the field are the strains produced by particle stresses exerted by gases in interplanetary space, by ...

On the geomagnetic storm effect

Journal of Geophysical Research, 1957
In a recent paper,1 an objection was raised against the “ring-current” hypothesis of geomagnetic storm effects, and an alternative hypothesis based on atmosphere displacements was advanced. The objection arose from the unacceptable delay, estimated at 87 days, required for the passage of the storm through the outer reaches of the earth's atmosphere ...

Forbush decreases and geomagnetic storms

Geomagnetizm i aèronomiâ
Forbush decreases in galactic cosmic rays (according to data from a network of neutron monitors) and accompanying geomagnetic disturbances over a long period from 1957 to 2022 have been identified and studied. Statistical relationships between various parameters of cosmic ray flux and geomagnetic activity indices are analyzed.

Recovery times of geomagnetic storms

Il Nuovo Cimento, 1963
Using the hourly values of the horizontal component of geomagnetic field at Alibag, India, the recovery times of several geomagnetic storms occuring during the period 1947-59 are evaluated. Relation between average recovery time and sunspot activity is studied. Bough parallelism is observed.
