2012 Solar Ion Storm? Is there really a super solar storm in 2012? What are the hazards?

It is the alpha charged particles (positive ions) that are thrown into space during the intense activity of the sun, and when solar flares appear, these particles will suddenly increase a lot, which will affect radio communications, affect the normal operation of satellites, and cause auroras. The Sun has a major explosion approximately every 11 years, and 11 years is also known as the solar cycle. But fortunately, we have a geomagnetic field to protect us, otherwise the earth's atmosphere would have been blown away long ago, and there would be no life.

However, due to the large change in the direction of the magnetic field lines at the magnetic pole, a part of the atmosphere can still come into contact with charged particles, and when the atmospheric ionosphere collides with the alpha charged particles, brilliance is generated, so the aurora is formed. However, the stronger charged particle wind (also known as the solar wind) will oppress the geomagnetic field, which may cause the magnetic field to be suppressed too low and the outer layer of the atmosphere will be destroyed, thus affecting the protective effect of the earth's atmosphere on the earth (mainly the filtration of this line), therefore, the growth of plants will be affected, and human beings will also face many diseases.

Therefore, the earth is already in a relatively mild dynamic equilibrium, and any factor that changes the existing state may break the existing ecological structure of the earth, which is extremely unfavorable to human beings. There is indeed such a statement about the high peak of solar activity in 2012, and it is relatively authoritative, but it is not known what the actual detection will be.

The solar storm prediction is in 2012! Will the prophesied crisis come true?

Liu Min, director of the GPS application development office of the city's satellite remote sensing and measurement application center, told reporters that the development of human society has made more and more sophisticated electronic instruments appear, "Take satellites as an example, the number of satellites has increased greatly compared with 11 years ago, which means that when solar storms appear, the probability of satellite damage is also increasing." Liu Min also believes that the possible solar storm around 2012 should not be ignored, such as the solar storm around 2000, the power grid in Quebec, Canada, was almost paralyzed, and then Japan's satellites were also damaged. "Although we are not yet sure how strong the solar storms will be in the future, it is certain that the more developed societies are, the more vulnerable they will be to such space weather disasters.

However, some experts pointed out that judging from the fact that the current solar activity is still in a relatively "moderate" state, the date of the peak year of solar activity proposed by American scientists in 2012 may be postponed. "This warning from American scientists has its scientific basis, but it is not so serious. Tang Haiming, director of science popularization at Sheshan Station of the Shanghai Astronomical Observatory, told reporters that for space weather disasters such as solar storms, the current scientific research results in China are that they will not be stronger than the one around 2000.

However, it is difficult to determine exactly what it will look like, and it is not yet clear whether it will cause secondary disasters.

As for whether the occurrence of a solar storm will have a radiation impact on the human body, Tang Haiming also said that according to the current judgment of intensity, the impact on the human body will not be very large.

How much of a solar storm did the 2012 solar storm affect the Earth? "The warnings of American scientists are not alarmist, but conclusions based on scientific research. Around 2012 was the 24th week peak year of solar activity.

However, it is completely unnecessary for us to panic about this. ”

A super solar storm is a flare eruption (commonly known as a solar storm) produced by the Sun at the peak of sunspot activity. Scientists later found that solar storms are high-speed particle streams formed by the increase in the sun's energy and the intensification of its own activity, thus releasing a large number of charged particles into the vast space. Solar storms usually enter the active phase every 11 years.

The solar storm that will occur around 2012 is super-strong and lacks scientific evidence.

At around 3 p.m. on January 20, 2005, a magnitude solar storm occurred in the Sun. Affected by the solar storm, the short-wave radio signals of the communication, broadcasting, and surveying systems in China were immediately absorbed by the strong ionosphere, and thus were interrupted, and the signals in Beijing were interrupted for more than an hour.

In addition, another important effect of solar storms on the Earth is that they cause magnetic storms, which can have an impact on the power supply system. On March 13, 1989, a severe magnetic storm during the 22nd week of solar activity caused a severe impact on the power grid of Quebec, Canada, paralyzing the power supply system in Quebec, and more than 6 million people spent nine hours in the winter without electricity. Not only that, but the strong magnetic storm also burned a giant transformer at a nuclear power plant in New Jersey, USA, as well as a large number of transmission lines, transformers, static compensators and other grid equipment tripped or damaged.
