Geomagnetic storms are temporary disturbances in the Earth's magnetosphere caused by changes in the interplanetary magnetic field. These changes can be caused by solar activity such as solar flares or coronal mass ejections.
Geomagnetic storms can cause disruptions in the Earth's magnetic field, which can affect power grids, radio communications, and satellite navigation systems in the Northern Hemisphere. They can also cause beautiful auroras in the night sky.
Geomagnetic storms occur on average about 200 times per 11-year solar cycle, but their frequency can vary depending on the level of solar activity. During periods of high solar activity, they can occur more frequently.
Geomagnetic storms are more common in the Northern Hemisphere because the Earth's magnetic field is stronger in the Northern Hemisphere, making it more susceptible to disturbances from solar activity.
Geomagnetic storms can cause disruptions in power grids, resulting in blackouts and damage to electrical equipment. They can also interfere with satellite navigation systems, which can be dangerous for air and sea travel. In rare cases, they can even affect human health by disrupting the Earth's magnetic field, which can interfere with the body's internal compass and cause disorientation and other symptoms.
