1. Popular science of geodetic magnetic storms.
A geodetic magnetic storm is a drastic change in the Earth's magnetic field over a short period of time, usually accompanied by an aurora phenomenon. This natural phenomenon has a certain impact on the earth's ecosystem, communication system, and navigation system.
1.Causes: The main cause of geomagnetic storms is the interaction between the stream of charged particles in the solar wind (also known as the solar wind) and the Earth's magnetic field. When a stream of charged particles in the solar wind hits the Earth's magnetic field at high speed, energy is released, causing a drastic change in the Earth's magnetic field.
2.Type: Geodetic magnetic storms are mainly divided into two types, namely C-type magnetic storms and X-type magnetic storms. Type C magnetic storms occur mainly in the Earth's magnetosphere and have low energy and less impact on the ground. X-type magnetic storms occur outside the Earth's magnetosphere and have higher energy and greater impact on the ground.
3.Impact: The impact of geodetic magnetic storms on the earth is mainly reflected in the following aspects:
a) Impact on communication systems: Magnetic storms can cause drastic changes in the geomagnetic field, which can affect the propagation of communication signals. During a magnetic storm, shortwave communications can be severely disrupted or even completely disrupted.
b) Impact on the navigation system: The impact of the geomagnetic storm on the Earth's magnetic field will be transmitted to the Earth's navigation system, such as compass, magnetic compass, etc. During a magnetic storm, these navigation devices may be misread or malfunction.
c) Impact on the power system: The electromagnetic radiation generated by the geomagnetic storm may induce currents to the transmission lines of the power system, resulting in damage to the power equipment. In addition, magnetic storms can cause grid voltage fluctuations, affecting power**.
d) Impact on aviation safety: Geomagnetic storms may affect electronic equipment on board aircraft, such as navigation equipment, communication equipment, etc. During a magnetic storm, airlines usually take certain measures, such as limiting flight altitude, changing routes, etc., to ensure flight safety.
4.Prevention and response: Due to the large impact of geomagnetic storms on the earth, countries** and scientific research institutions are actively carrying out relevant research in order to find effective prevention and response measures. At present, some countries have established special magnetic storm monitoring and early warning systems to take timely measures to mitigate the impact of magnetic storms on the ground when they occur.
Second, the geomagnetic storm is coming, and human beings need to pay attention.
1.Protect electronic devices: Geomagnetic storms can interfere with electronic devices, causing them to be damaged or malfunction. Therefore, people need to take measures to protect their electronic devices, such as using electromagnetic shielding devices, backing up important data, etc.
2.Pay attention to traffic safety: Geomagnetic storms may affect navigation systems and communication equipment, causing traffic chaos and accidents. People need to pay attention to traffic safety, follow traffic rules, and avoid traveling long distances during magnetic storms.
3.Pay attention to the weather forecast: Geomagnetic storms may have an impact on the weather, such as triggering extreme weather such as thunderstorms and storms. People need to pay attention to the weather forecast, keep abreast of weather changes, and take corresponding protective measures.
4.Stay healthy: Earth-magnetic storms can have an impact on human health, such as headaches, insomnia, anxiety, and other symptoms. People need to maintain good Xi, maintain adequate sleep and diet, and avoid excessive fatigue and stress.
5.Seek help: In the event of an emergency caused by a geomagnetic storm, people should seek help promptly. You can call local emergency services** or reach out to someone nearby.
