Geomagnetic Storm Main Phase Effect on the Equatorial Ionosphere over Ile-Ife as measured using GPS Observations [PDF]

open access: yesarXiv, 2019
The effect of the main phase of two intense geomagnetic storm events which occurred on August 5 - 6 and September 26 - 27, 2011 on the equatorial ionosphere have been investigated using Global Positioning System (GPS) data obtained from an Ile-Ife station (geomagnetic lat. \ang{9.84}N, long. 77.25 degree E, Dip \ang{7.25}N).

The aurora as a source of planetary-scale waves in the middle atmosphere [PDF]

open access: yes
Photographs of global-scale auroral forms taken by scanning radiometers onboard U.S. Air Force weather satellites in 1972 show that auroral bands exhibit well-organized wave motion with typical zonal wave number of 5 or so.

Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]

open access: yes, 2004
Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

The geomagnetic storm time response of GPS total electron content in the North American sector

open access: yes, 2016
Over the last two decades, maps of GPS total electron content (TEC) have improved our understanding of the large perturbations in ionospheric electron density which occur during geomagnetic storms.

Enhancement in Surface Atmospheric Pressure Variability Associated with a Major Geomagnetic Storm [PDF]

open access: yesarXiv, 1998
Observational studies indicate that there is a close association between geomagnetic storm and meteorological parameters. Geomagnetic field lines follow closely the isobars of surface pressure . A Physical mechanism linking upper atmospheric geomagnetic storm disturbances with tropospheric weather has been proposed by the author and her group where it ...

TEC enhancement due to energetic electrons above Taiwan and the West Pacific

open access: yes, 2013
The energetic electrons of the inner radiation belt during a geomagnetic disturbance can penetrate in the forbidden range of drift shells located at the heights of the topside equatorial ionosphere (

Ionosphere data assimilation modeling of 2015 St. Patrick's Day geomagnetic storm

open access: yes, 2016
The ionospheric plasma disturbances during a severe storm can affect human activities and systems, such as navigation and HF communication systems. Therefore, the forecast of ionospheric electron density is becoming an important topic recently.

Analysis of the monitoring data of geomagnetic storm interference in the electrification system of a high‐speed railway

open access: yes, 2016
To study the impact of geomagnetic storm on the equipment of traction electrification system in the high‐speed railway, geomagnetically induced current (GIC) monitoring devices were installed in the Hebi East traction power supply substation of the ...
