A Theory of Polar Geomagnetic Storms [PDF]

Geophysical Journal International, 1960
A third part of the hydromagnetic theory of geomagnetic storms is obtained. The first two parts deal with the storm-time variations Dst in terms of isotropically propagating hydromagnetic compression (first phase) and rarefaction (main phase) of the geomagnetic field and its plasma.

Mid-latitude ionosphere during two great geomagnetic storms

Annals of Geophysics, 1996
The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

Localized Increment and Decrement in the Total Electron Content of the Ionosphere as a Response to the April 20, 2018, Geomagnetic Storm

International Journal of Geophysics, 2018
A moderate geomagnetic storm occurred on April 20, 2018. Using vertical total electron content (VTEC) maps provided by the Center for Orbit Determination in Europe, ionospheric responses to the geomagnetic storm could be identified in generated two ...

ED‐Autoformer: A New Model for Precise Global TEC Forecast

Space Weather
Total electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC

Forecast of Ionospheric TEC Maps Using ConvGRU Deep Learning Over China

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this article, we propose a convolutional gated recurrent unit (ConvGRU) deep learning method to forecast ionospheric total electron content (TEC) over China based on the regional ionospheric maps (RIMs) from 2015 to 2018.

Effect of the 1 December 2023 Geomagnetic Storm on SPP Performance in China

Space Weather
Geomagnetic storms, precipitated by solar phenomena such as coronal mass ejections (CMEs), profoundly disturb the Earth's magnetic field, impacting satellite‐based navigation systems.
