Relation between substorm characteristics and rapid temporal variations of the ground magnetic field [PDF]
, 2006 Auroral substorms are one of the major causes of large geomagnetically induced currents (GIC) in technological systems. This study deals with different phases of the auroral substorm concerning their severity from the GIC viewpoint. Our database consists

Modelling of geomagnetically induced currents in the Czech transmission grid
Earth, Planets and Space, 2021 We investigate the maximum expected magnitudes of the geomagnetically induced currents (GICs) in the Czech transmission power network. We compute a model utilising the Lehtinen–Pirjola method, considering the plane-wave model of the geoelectric field ...

Generation of 100‐year geomagnetically induced current scenarios [PDF]
Space Weather, 2012 A series of 100‐year extreme geoelectric field and geomagnetically induced current (GIC) scenarios are explored by taking into account the key geophysical factors associated with the geomagnetic induction process. More specifically, we derive explicit geoelectric field temporal profiles as a function of ground conductivity structures and geomagnetic ...

S‐transform view of geomagnetically induced currents during geomagnetic superstorms [PDF]
Geophysical Research Letters, 2006 A novel time‐frequency analysis method (S‐transform) capable of handling noisy non‐stationary signals is applied to study the properties of geomagnetically induced current (GIC) fluctuations in the Finnish natural gas pipeline. New local time‐ and storm phase‐dependent S‐transform spectral properties of auroral region GIC fluctuations during ...
