Will the attack of solar storm have an impact on human life? Why?

Although the solar wind is fierce, it will not blow to the earth. This is because the earth has its own umbrella-the earth's magnetic field. The geomagnetic field of the solar storm shields the sun from the earth. However, there will still be a few molecules escaping from the net, although only a few; But it will still bring a series of harm to the earth. It will interfere with the earth's magnetic field and make the intensity of the earth's magnetic field change obviously; It will also affect the upper atmosphere of the earth, destroy the structure of the ionosphere of the earth, make it lose the ability to reflect radio waves, and cause the interruption of our radio communication; It will also affect the chemical changes of the ozone layer in the atmosphere, and transmit it layer by layer until it reaches the earth's surface, causing abnormal changes in the earth's climate, and even further affecting the earth's crust, triggering volcanic eruptions and earthquakes. For example, on July 1959 and 15, people observed that the sun suddenly emitted a huge flame (this is the wind source of the solar wind). A few days later, on July 2 1 day, when this violent solar wind hit the earth's adjacent space, the earth's rotation speed suddenly slowed down by 0.85 milliseconds, and many earthquakes occurred around the world that day; At the same time, the geomagnetic field was violently disturbed by the so-called "magnetic storm", and global communication was suddenly interrupted, making some planes and ships that rely on compasses and radio navigation suddenly become "blind" and "deaf". The influence of the solar wind on the earth is only the work of molecules that escape from the net. This shows how powerful the solar wind is in the barrier-free interstellar space. Where the solar wind meets the interstellar matter outside, a shock wave will be generated. The "Voyager 1" probe launched by 1977 is said to have encountered such a shock wave in 2003. That shock wave is about 65.438+0.28 billion kilometers from the sun ~ 65.438+0.8 billion kilometers. The influence of solar wind on human beings;

1. When the solar wind passes over the earth, it will change the electromagnetic field, cause geomagnetic storms and ionospheric storms, and affect communication, especially short-wave communication.

2. Send powerful elements (original? ) charges, affecting the safety of power transmission and oil and gas pipeline systems.

3. It will also have an impact on satellites in operation.

4. The radiation of solar wind can easily reach one person's X-ray examination. It will also cause the decline of human immunity, easily cause pathological changes, make people's emotions fluctuate easily, and even increase car accidents.

It will raise the temperature.

6. Aurora is formed in the North Pole and the South Pole.

A house whose windows are blown open by the wind can resist the attack of storms as a whole, but the strong wind that breaks through the window will blow the house into a mess. The latest research shows that the earth's magnetic field is like a house prone to "rain leakage" in front of the solar wind, and its "rain leakage" will last for several hours, providing an opportunity for charged particles from the sun to enter the earth's atmosphere and disrupt communication and power systems. Solar Storm In the latest issue of the British journal Nature, researchers at the University of California, Berkeley published this research result. The researchers said that the new results will help to better predict the possible impact of bad "space weather" such as solar storms on the earth. From time to time, the sun blows out a solar wind composed of charged particles. If the solar activity becomes violent, so will the solar wind. The earth itself has a magnetic field extending tens of thousands of kilometers into space, which can form a protective barrier against the solar wind. However, this obstacle is not without defects. As early as 196 1 year, Dr. Deng Gai of Imperial College London, London, England predicted that when the direction of the magnetic field contained in the solar wind is partially opposite to that of the earth's magnetic field, the process of "magnetic reconnection" between the two magnetic fields will lead to a gap in the earth's magnetic field protection barrier, so that charged particles of the solar wind can take advantage of it. Other scientists later confirmed the existence of this gap, but scientists have been unclear whether this gap in the earth's magnetic field is intermittent or will remain open for a long time. Frey of the University of California, Berkeley, said that he and his colleagues found for the first time that the gap in the earth's magnetic field would open for several hours with the help of NASA's image detector and the observation data of satellites belonging to the European and American "cluster" project. According to their calculations, on the boundary of the Earth's magnetic field barrier, which is about 60,000 kilometers away from the Earth's surface, the gap area may reach twice the earth's area, and the solar wind thus entering will eventually produce a proton aurora equivalent to the size of California in the ionosphere above the North Pole.

A few days ago, NASA gave a very rare warning that the earth may encounter a strong solar storm, and the time point is three years later, that is, 20 13. At that time, the world will be plunged into darkness, and all network electronic communications will be unusable. If the nightmare comes true, human life will go backwards in history. In recent years, scientists have found that a magnetosphere protects the earth like a huge soap bubble, and it is getting thinner and thinner. On March 30, 2008, the extreme ultraviolet multi-wavelength panorama of the sun was 65438+February, and NASA announced that it had found a big hole in the magnetosphere, which was four times wider than the earth and was still expanding. All kinds of harmful particles discharged from outer space to the earth will directly impact natural things and human society. It has happened several times in the past, and scientists have accurately predicted the coming next solar storm, which will be on September 22, 20 12. This statement aroused the interest of Hollywood. Hollywood movies "20 12" and "doomsday prediction" both simulate the horror scene of the end of the world when natural disasters hit the earth, and the ancient Mayan calendar also has similar predictions. However, a senior scientist of NASA warned that this possible "doomsday scene" did not happen in 20 12, but in 20 13. Scientists point out that solar activity will wake up from the dormant period around 20 13. At that time, there will be a large-scale coronal eruption, and the huge flash flame power is equivalent to 100 hydrogen bombs exploding and hitting the earth's magnetosphere instantly. Scientists, government policy makers and researchers from NASA gathered at the National Press Club in Washington, D.C. last week for the Space Atmosphere Summit Forum. Experts discussed at the meeting that the sun may fall asleep from its deep sleep around 20 13, and then enter an active period, and the subsequent solar storm will have a serious impact on the earth. Experts say that the impact of the terrible solar storm is beyond imagination. At the peak of activity, sunspots will produce violent explosions and trigger solar storms. When sunspots erupt, a large number of charged particles will be released, which may plunge the whole earth into darkness. Not only is electricity unavailable, the ozone layer is destroyed, but electronic communication may be completely shut down, such as hospitals, banks and airports, not to mention personal mobile phones, computers and satellite positioning systems. If all this comes true, the economic losses suffered by human beings are estimated to be 20 times that of Hurricane Katrina (Hurricane Katrina hit New Orleans in 2005, causing losses of $654.38+025 billion). Astronomical experts pointed out that sunspot activity takes every 1 1 year as a cycle, the earth experienced a powerful solar storm in 1859, and the interaction between the Northern Lights and volcanic ejecta [4] was 15 1 year ago. But at that time, power communication was underdeveloped, so it didn't cause a big disaster. Worried about the serious impact of solar storms on the earth, scientists began to closely monitor the sun, and planned to switch the satellite to safe mode as soon as possible during the frequent solar storms to reduce the damage. In fact, scientists have been pursuing for decades to improve the accuracy of space weather forecasting technology, hoping to avoid the threat of solar storms. NASA's solar dynamic observation satellite was launched from Cape Canaveral Air Force Base in Florida on February 1 1 this year, and entered a geosynchronous orbit about 36,000 kilometers above the surface, so as to monitor the sun for 24 hours, hoping to learn more about the internal structure and magnetic field activities of the sun.
