Randomness in Geomagnetic Storms
Fractals, 1997Although geomagnetic forecasting is extremely important, geomagnetic predictions usually rely on forecasters' experience in distinguishing events expected to be geoeffective. Initial investigations with powerful forecasting techniques such as neural networks have recently been applied to geomagnetic prediction, but these are based on the assumption ...

Bracing for the geomagnetic storms
IEEE Spectrum, 1990As 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.

On the cause of geomagnetic storms
Journal of Geophysical Research, 1974A study of the solar wind and interplanetary magnetic field during four geomagnetic storms shows that strong southward interplanetary magnetic fields are associated with the development of each main phase. Weak southward magnetic fields do not necessarily lead to an increase in the ring current even though such southward fields persist.

Geomagnetic Index for Intense Ionospheric Storm
2019 Russian Open Conference on Radio Wave Propagation (RWP), 2019© 2019 IEEE. From analysis of the geomagnetic activity indices aa and ap it is obtained that the index aa can be more adequate indicator of geomagnetic activity for the ionospheric parameters at periods of maxima of intense magnetic storms than ap. This is supported by analysis of the F2-layer critical frequency over Irkutsk station at the period of ...

Extreme Geomagnetic Storms – 1868 – 2010
Solar Physics, 2016We present the first large statistical study of extreme geomagnetic storms based on historical data from the time period 1868 - 2010. This article is the first of two companion papers. Here we describe how the storms were selected and focus on their near-Earth characteristics.
