Abstract We present a study on the dynamical variations of geoelectric fields E during the intense geomagnetic storm of April 23–24, 2023. The storm is caused by the interplanetary counterpart of a coronal mass ejection erupted from the Sun in asso

AbstractThis paper reports three methods of researching the geoelectric index (GEI) based on the ratio between the variation amplitude of geoelectric field on an index calculation day and that on a magnetically quiet day, and uses the three methods t

Historically, Sweden has reported several impacts on transformers and transmission lines related to geomagnetically induced currents (GICs) that develop during strong space weather events. GICs are driven by the geoelectric field (E), and their inten

The quality of the geoelectric field data of Wenchang Wengtian station in Hainan Province has been declining since March 2019. The quality of the geoelectric field data has declined mainly due to the low daily correlation coefficient, the reverse cha

Geomagnetic disturbances caused by solar activities induce geoelectric fields on the earth's surface, which generate geomagnetically induced currents (GICs) in electrically conducting systems. Magnetic storms caused by anomalous solar activities prod
