A study from an international team led by researchers from Nagoya University in Japan and the University of New Hampshire in the United States has revealed the importance of the Earth’s upper atmosphere in determining how large geomagnetic storms develop. Their findings reveal the previously underestimated importance of the Earth’s atmosphere. Understanding the factors that cause geomagnetic storms is important because they can have a direct impact on the Earth’s magnetic field such as causing unwanted currents in the power grid and disrupting radio signals and GPS. This research may help predict the storms that will have the greatest consequences.

Scientists have long known that geomagnetic storms are associated with the activities of the Sun...

In connection with violent solar eruptions, large variations occur in electron density in the ionosphere over Greenland, which interferes with GPH navigation signals as well as flight and satellite communication. The figure (right) shows large electron density in red and small density in blue. This phenomenon gives rise to high electron speeds in the ionosphere, exceeding 1,000 metres per second (left) and resulting in violent energy bursts. For the first time ever, researchers from DTU have demonstrated the phenomenon which cannot yet be explained. (Illustration: DTU Space).

New research from DTU, JPL and University of New Brunswick shows that eruptions on the Sun’s surface not only send bursts of energetic particles into Earth’s atmosphere causing disturbances in our planet’s magnetic fi...
