Geomagnetic storm - Wikipedia
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave.
Geomagnetic Storms - NOAA / NWS Space Weather Prediction …
A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.

2024年12月1日 · Geomagnetic storm, disturbance of Earth’s upper atmosphere brought on by coronal mass ejections—i.e., large eruptions from the Sun’s outer atmosphere, or corona. The material associated with these eruptions consists primarily of protons and electrons with an energy of a few thousand electron volts.

2024年5月21日 · What is a Magnetic Storm? A magnetic storm is a disturbance in the Earth's magnetic field caused by coronal mass ejections (CMEs) or solar flares from the Sun. It usually begins between 24 and 36 hours after the solar event, when a shock wave of solar wind reaches the Earth's ionosphere.
