Geomagnetic storms, a mysterious and magnificent phenomenon, are not uncommon moments in the long history of mankind. However, due to the fragmentation and ambiguity of our understanding of it, it often loses its original brilliance in ignorance and misunderstanding. This article will try to demystify geomagnetic storms, take you through their glory from ancient times to the present, and its profound impact on our lives.
Geomagnetic storms, a unique performance in nature, are as beautiful as nature's fireworks. Its appearance is often accompanied by the sparkle of stars, the intertwining of thunder and lightning, and the crimson of the sky. However, we know very little about this phenomenon, which seems to be closely related to our daily lives. We don't know why it happens, we don't know how big its impact is, or even what role it plays in our lives.
History is a recorder and a witness of time. Through the historical record, we can get a glimpse of the shadow of the geomagnetic storm. In ancient texts, we can find descriptions of geomagnetic storms, which may be vague but true. These descriptions are both a gift from nature and a human exploration of the unknown.
The impact of geomagnetic storms is far-reaching, affecting not only our weather systems, but also our communications, aviation, and even the military. Its existence makes our world richer and more diverse, and it also makes us have more awe and respect for nature. Although we cannot ** the arrival of geomagnetic storms, we can understand it and prevent it to reduce the damage it may bring.
Geomagnetic storms are a natural phenomenon that we are both familiar with and unfamiliar to. It both leaves a deep mark on our lives and puts obstacles in our way to understanding it. However, this does not affect our determination to pursue knowledge and explore the unknown. Let's unravel the mystery of geomagnetic storms together, appreciate its beauty, and understand its power to better protect our lives.
1. Causes of geomagnetic storms.
The high-velocity plasma cloud is ejected from the solar corona, and its velocity is higher relative to the background solar wind, carrying the coronal magnetic field to impact the Earth's magnetosphere, causing the magnetosphere to compress and deform. Normally, it also carries a magnetic field that rotates in the north-south direction, and when the magnetic field turns to the south and interacts with the geomagnetic field, the solar wind will pour huge energy into the large-scale space of the magnetic tail like a violent flood, so that many charged particles in the magnetic tail plasma sheet are injected into the ring current, resulting in a change in the ring current intensity. The changing current in turn triggers a changing magnetic field, which in turn triggers a violent geomagnetic disturbance on a global scale – geomagnetic storms.
If the earth is compared to a house, then when a lightning bolt hits the house, the lightning that hits it is the solar wind, and the resulting phenomenon is a geomagnetic storm, and its external manifestation is the generation of auroras. As the source of geomagnetic storms, the solar wind has two major categories: solar coronal mass ejection (CME) and solar coronal holes.
3. Geomagnetic storms recorded in history.
In the last years of the Ming Dynasty, a geomagnetic storm caused earth-shattering changes over East Asia. The sky turned red, as if engulfed in red flames, and the raging flames lasted for nine days. This change has had a profound impact not only in East Asia, but also in Japan and Europe. At that time, the burning sky was like being dyed red by a huge torch in the northeast area where I passed, as if the end was coming.
A Portuguese observer vividly paints a picture of the scene: "A raging fire arose in the northern sky, which lasted for three days and three nights. "The fire seemed to have turned the entire sky blood-red, terrifying and shocking. It not only illuminates the sky, but also ignites the fear in people's hearts and the wonder of the unknown.
This geomagnetic storm and the vision of burning the sky are now part of history, remaining in people's memories and documents. However, the scene at that time is still vivid, as if it were yesterday, and one cannot help but marvel at the mystery and power of nature.
1770 geomagnetic storm event.
The geomagnetic storm of 1770 swept the entire earth like a sudden storm. From 8 to 12 April, the strength of the geomagnetic field dropped sharply until it reached an all-time low on 11 April. After this storm, the geomagnetic field gradually recovered and returned to normal. This rare geomagnetic storm event left a strong mark in the scientific literature of the time, and even Edward Carrington's solar observation record.
Historical records show that this geomagnetic storm had a significant impact on the society at that time. Changes in the geomagnetic field caused electrical equipment such as telegraphs and bells to fail to work normally, and even telegraph lines were disconnected. In the records of the East Asian courts, a blood-colored sky appeared in 1770, a strange phenomenon that appeared for nine consecutive nights. The aurora was even more rare at low latitudes, all of which was recorded by the crew of the Endeavour near the island of Timor in Southeast Asia at the time.
As for the cause of this geomagnetic storm, scientists generally believe that it is related to solar activity. It was at the peak of solar activity, and increased activity such as sunspots and solar storms could have an impact on the Earth's magnetic field, leading to geomagnetic storms.
The geomagnetic storm event of 1770 is a geomagnetic storm event recorded in history, which is like a mirror, reflecting the true appearance of geomagnetic storms. Its social and economic impact is large enough to cause our attention. By studying and analyzing this historical record, we can better understand the nature and possible effects of geomagnetic storms, which can provide valuable references for future research and applications.
Carrington Affair of 1859.
In the early morning of September 1, 1859, an astronomer named Carrington was observing sunspots when he spotted a geomagnetic storm. Like a huge storm that suddenly erupts, 17 and a half hours later, the hands of the geomagnetic meter jump out of the scale due to the super-strong geomagnetic intensity. It's like a raging beast, dancing wildly beyond the calm scale. Almost at the same time, operators of telegraph machines in telegraph offices everywhere reported that their machines were flashing sparks and even the wires were melting. It's like a fiery feast that melts the metal and illuminates the darkness.
People at high latitudes can see the colorful Northern Lights in the sky and read the newspaper at midnight without lighting the lights. It's like a giant picture scroll that hangs down from the sky and dyes the world in a riot of colors. Carrington almost certainly believed that these events were all related to the flare outbreak he had discovered. He felt like a prophet of fate, foreseeing the catastrophe of this world.
Carrington Incident"This caused 8 days of severe space weather. This grand show did not bring too much disaster to the earth. After all, the world at that time relied mainly on steam engines and labor, and there were no artificial satellites, radio communications, and modern power transmission networks. However, this solar storm still brought great shock and awe to the people. It makes people realize that the power of the sun is so powerful, so mysterious, and that we are so small.
In the midst of the raving of disaster, Carrington's discovery opens a new window for humanity. Since then, people have begun to pay attention to and study the sun, and its impact on the earth. Not only does this give us a deeper understanding of the sun, but it also gives us more awe of the star that gives us life.
3. The impact of geomagnetic storms on humans.
During a geomagnetic storm, the Earth's magnetic field changes, acting like a stage of disturbance, causing interference in the transmission of radio signals. Under the impact of a strong magnetic storm, the radio signal can be completely blocked, causing communication to be interrupted, as if the whole world was overwhelmed by a great wave of silence. In addition, geomagnetic storms are like a naughty child, quietly affecting the accuracy of satellite navigation systems, bringing safety hazards to aviation, shipping and other transportation industries, like throwing a stone on the calm sea, making the originally smooth navigation become choppy.
Geomagnetic storms can cause grid voltage fluctuations, like gusts of wind, blowing the big ship of the grid and causing it to shake, causing power outages or equipment damage. In extreme cases, geomagnetic storms may become the last straw that crushes the camel, causing the paralysis of the entire power system, bringing great inconvenience to people's production and life, just like being choked by the throat and suffocating.
Geomagnetic storms can affect the space environment, causing a large number of charged particles to accumulate in space and surge like a storm. These charged particles pose a threat to space vehicles and astronauts, affecting the normal conduct of space activities. Geomagnetic storms are like a dark shadow that hangs over people's heads and can cause disaster at any time.
Geomagnetic storms can cause climate change. Studies have shown that the strength of geomagnetic activity is closely related to climate change. In some cases, geomagnetic storms can cause climate anomalies with catastrophic effects on humans. It's like setting off huge waves in an otherwise calm climate ocean, causing unpredictable harm to both humans and nature.
Geomagnetic storms can also have some negative effects on the body. Geomagnetic storms can interfere with the nervous system in humans, causing people to experience symptoms such as headaches, dizziness, insomnia, dreaminess, nausea, vomiting, etc. These symptoms are like dark ghosts that haunt people's lives and work. At the same time, geomagnetic storms can also affect the cardiovascular system, causing people to experience symptoms such as irregular heartbeat, rapid heartbeat, and blood pressure fluctuations. These symptoms are like invisible claws, quietly reaching out to the source of people's life.
In addition, geomagnetic storms can also affect the human immune system. During a magnetic storm, people's immunity may be weakened and they are more susceptible to disease, as if it opened a gap in people's already strong immunity walls, allowing germs to take advantage of the gap. These effects have cast a shadow on people's lives, making people full of anxiety and anxiety about the days ahead.
Fourth, the impact of geomagnetic storms on **.
Geomagnetic storms are considered to be an important factor in the study. Some studies have shown that geomagnetic storms can cause changes in current in the Earth's crust, resulting in pressure and tension. This occurs when these pressures and tensions exceed the capacity of the earth's crust. In addition, geomagnetic storms can also affect the magnitude and frequency of earthquakes.
In order to further study the relationship between geomagnetic storms and **, scientists conducted a series of experiments. These experiments include monitoring changes in current in the Earth's crust during geomagnetic storms, as well as studying the effects of geomagnetic storms on crustal stresses. Through these experiments, scientists have found some interesting conclusions.
There is a relationship between the change of current in the earth's crust and the magnitude and frequency of ** during geomagnetic storms. Some studies have shown that the greater the change in the current in the earth's crust during a geomagnetic storm, the higher the magnitude and frequency of **. This suggests that geomagnetic storms may be one of the most important factors influencing **.
The effect of geomagnetic storms on crustal stresses has also been confirmed. In the experiment, scientists found that geomagnetic storms cause changes in crustal stresses. These changes can cause faults and fissures in the earth's crust to expand or contract, increasing or decreasing the risk.
There may be a link between geomagnetic storms and **. While more research is needed to confirm this idea, scientists believe that geomagnetic storms could be one of the important tools for both and prevention. By monitoring geomagnetic storms and changes in current in the Earth's crust, it is possible to better understand the risk and occurrence of **. This will help reduce the losses caused by ** and protect people's lives and property.
4. Warning and prevention.
Geomagnetic storms can cause changes in the Earth's magnetic field, which can affect the normal operation of systems such as electricity, communications, and satellite navigation. Therefore, it is very necessary to understand the warning and preventive measures of geomagnetic storms.
Warnings of geomagnetic storms are very important. Before a geomagnetic storm occurs, the Earth's magnetic field changes, which can lead to problems such as power system failures, errors in satellite navigation, and disruptions in communication systems. Therefore, relevant departments should strengthen the monitoring and early warning of geomagnetic storms, and release early warning information in a timely manner, so that people can take preventive measures.
Precautions against geomagnetic storms are also very important. First and foremost, people should pay attention to their own safety. In the event of a geomagnetic storm, the use of electronic equipment, especially high-precision electronic equipment, such as satellite navigators, radars, etc., should be avoided. At the same time, you should also avoid going out or using outdoor electrical equipment during thunderstorms. Second, measures should be taken to ensure public safety. In the event of a geomagnetic storm, the emergency plan should be activated in time to strengthen the monitoring and maintenance of power, communication, transportation and other systems to ensure public safety.
We should strengthen the study and exploration of geomagnetic storms. There are still many unknowns about the generation mechanism and impact range of geomagnetic storms, so we need to strengthen the research and exploration of geomagnetic storms in order to better respond to geomagnetic storms. At the same time, we also need to strengthen the public's awareness and understanding of geomagnetic storms, and improve the public's scientific literacy and safety awareness.
