Risk Assessment of Geomagnetically Induced Currents (GICs) Over the Indian Sector in Comparison With American and African Sectors

Space Weather
Geomagnetically Induced Currents (GICs) are the manifestation of adverse space weather events on the ground that poses serious threats to power grids as well as pipelines. Extensive investigations on the impact of GICs at high and mid‐latitudes have been

Equatorial Electrojet & Total Electron Content Anomaly

, 1979
44-46Total electron content equatorial anomaly is studied in relation to the electrojet strength using beacon signals from geostationary satellite ATS-6 recorded at Bombay Rajkot, Ahmedabad, Udaipur and Patiala. The anomaly is seen to maximize after 3-31

Simultaneous electric field changes in the equatorial electrojet in phase with polar cusp latitude changes during a magnetic storm

, 1985
The Doppler frequency of the VHF radar signals backscattered from the drifting ionization irregularities in the equatorial electrojet is proportional to the east-west electric field Ey in the equatorial electrojet.

2‐Day Ionospheric Oscillations at Low Latitudes Due To an Ultra‐Fast Kelvin Wave

Earth and Space Science
This study establishes an observational connection between an ultra‐fast Kelvin wave (UFKW) and the occurrence of counter electrojet (CEJ) in the equatorial E region and planetary wave‐like oscillations in low‐latitude total electron content (TEC), based
