GEOMAGNETICALLY INDUCED CURRENTS CALCULATION DURING GEOMAGNETIC DISTURBANCES

POWER ENGINEERING: economics, technique, ecology, 2016
A new method is presented to calculate geo-electric field using uniform Earth structure model for defining surface potential between grounded neutral of grid power transformers. It was calculated geo-electric field applying direct and inverse Fourier transform and calculated a surface impedance as a function of frequency of magnetic field oscillation ...

Aurora and Geomagnetic Disturbance

Nature, 1939
IN the course of analysis of simultaneous auroral and geomagnetic events at Fort Rae, North West Canada, during the Second International Polar Year, a feature has emerged about which we consider it advisable to make a preliminary report. If the elevation above the horizon of an auroral arc be φ, and if θ be the elevation of a concentrated linear ...

Solar activity and geomagnetic disturbances

Geomagnetism and Aeronomy, 2013
An analysis of IZNIRAN magnetic observatory data indicated that geomagnetic storms with sudden and gradual commencements form two independent populations with respect to the disturbance occurrence time and character because the solar sources of these disturbances are different.

Geomagnetic Disturbance and the Troposphere

Nature, 1969
THERE have been many searches for a possible influence of solar or magnetic disturbance on the troposphere, either for a direct effect or for one operating indirectly through propagation downwards from the upper to the lower atmosphere. Due to the many complex and variable factors involved, it has not proved easy to establish any clear-cut evidence for

Polar geomagnetic disturbances

Planetary and Space Science, 1963
Results of recent observations of geomagnetic disturbances in both northern and southern high latitudes are critically reviewed, and various theories on these phenomena are introduced. In Section 1, an additional geomagnetic daily variation, observed in the polar areas on magnetically quiet days, is discussed.
