Abstract: The effects of geomagnetic pulsations on the Doppler shifts of HF backscatter radar echoes are studied. Three mechanisms are considered: (1) variation of the phase refractive index under the ...
When these CMEs hit our planet, they can create massive disturbances in Earth's magnetic field, known as geomagnetic storms, potentially triggering radio blackouts and widespread aurora displays.
Finally, a comparative analysis of QP emissions and geomagnetic field pulsations revealed a close association between certain types of QP emissions and geomagnetic activity. This study found that ...
lead to the generation of some of the ULF geomagnetic pulsations commonly observed on the ground. In addition, it may also be significant that the frequencies associated with these hydromagnetic waves ...
Fast solar wind from a massive coronal hole in the sun could trigger dazzling auroral displays as geomagnetic activity is predicted to ramp up again over the weekend. A massive coronal hole has ...
A minor or greater geomagnetic storm is expected following the arrival of a coronal mass ejection emitted from the sun on Jan. 2, NOAA said, which could result in some power grid fluctuations and ...
