On December 1, geomagnetic storms may occur in China, of which geomagnetic storms above moderate or even geomagnetic storms may occur on December 1. The space station may be dragged by the atmosphere to reduce its orbital altitude, the error of satellite navigation equipment will increase, and the aviation flight will face the dual challenges of complex communication environment and transpolar radiation. In this regard, all walks of life should pay attention to the new developments in the field of space weather, especially pigeon enthusiasts and aurora enthusiasts need to pay special attention to relevant information in the next few days. Since December 2019, the Sun has entered its 25th cycle of activity, with a peak around 2025. Have you seen the aurora in many places across the country?
It's worth noting that while most people think that the aurora can only appear at high latitudes, in fact, there are opportunities to see the aurora at low and mid-latitudes. This is due to the release of large quantities of charged particles, especially electrons and protons, from solar activity. When these particles are captured by the Earth's magnetic field, they accelerate towards the Earth's poles. Once they reach the atmosphere above the polar regions, they collide violently with air molecules, creating a brilliant aurora.
What are the effects of geomagnetic storms on the Earth?
Experts answered the question about the impact of geomagnetic storms on shortwave communications. It is said that although such incidents do not cause significant harm to human health, the impact on the human body can be considered insignificant due to the short duration of their effects. This phenomenon is caused by the drastic changes in the Earth's magnetic field caused by solar activity, which are mainly manifested by currents, magnetic field fluctuations and plasma disturbances. At the same time, these changes can make it difficult to transmit radio waves, affecting short-wave communications due to hysteresis effects. For example, a radio signal may be directed in a different direction or disappear altogether as it travels through a storm.
Geomagnetic storms have a wide range of effects on the Earth. First, it causes an increase in the ionospheric ionization in the atmosphere, which affects the transmission and reception of radio signals, potentially causing communication disruptions worldwide.
Secondly, geomagnetic storms will cause strong electromagnetic radiation, interfere with the earth's magnetic field environment, cause the accuracy of compasses, satellites, GPS positioning systems, etc. to be affected, and cause aviation and navigation safety hazards.
In addition, geomagnetic storms can trigger auroras, which are caused by energetic particles hitting the atmosphere. The aurora phenomenon is not only beautiful and spectacular, but also has research value, helping to understand the magnetic environment of the solar system and the Earth.
The impact of geomagnetic storms on human health cannot be ignored. Long-term exposure to geomagnetic storms can have negative effects on a person's nervous system, cardiovascular system, and endocrine system. For life on Earth, geomagnetic storms can be a life-and-death natural disaster, which must arouse our great concern and active response.
