The film "2012" not only brought a strong visual impact to people, but also opened the prelude to people's panic about the end of the world. Recently, the crazy spread of the news that "a super solar storm will break out on September 22, 2012" has made people more worried. Will there really be a super solar storm in 2012? How do catastrophic space weather events like solar storms affect our lives? Wang Jinsong, Deputy Director of the National Satellite Meteorological Center and Director of the National Space Weather Monitoring and Early Warning Center, will be invited to answer the questions one by one in this weather view.

"The impact of space weather is mainly on high-tech systems, so the more developed places are, the more seriously affected by space weather. For example, if space weather events occur now, Somalia will certainly have no impact, but the United States will suffer heavy losses."
"The impact of catastrophic space weather events on human society is mainly concentrated in socio-economic aspects, rather than human survival problems." 
According to the Internet, the Earth ushered in a "super solar storm" in 2012
Will there be a super solar storm in 2012?
"In fact, no one predicted that there would be a solar storm in 2012. We originally thought that 2012 would be the next year of high solar activity. In such a year, there would be more solar activity and the probability of eruption would increase." According to the data, in the past year, 2009, the solar activity was slightly higher than that in previous years, but it was basically stable. As for the next solar high year, although it was generally thought that it was 2012, "at present, everyone's predictions are biased towards the arrival of 2013 or 2014." Therefore, there is no evidence to prove that 2012 will be a strong solar storm, and the news spread on the Internet is just a gimmick out of context. However, Wang Jinsong also revealed that although it is still uncertain when a solar storm will occur, with the intensification of solar activity, whether in 2012 or 2013, or in the next year, this event will one day break out and will eventually have a significant impact on human society. So, how does the disastrous space weather like the solar storm affect the operation of human society? Access details 
What is a solar storm? How does it affect the operation of human society?
In fact, solar storm is a kind of disastrous space weather. With the development and utilization of space, the weather environment in space has become a subject that people need to understand urgently, and the word "space weather" came into being. Just as the weather can be good or bad, space weather can be good or bad. When the space weather changes very violently, it will have a serious impact on human technology systems. This space weather is called disastrous space weather. At present, disastrous space weather events can be summarized as "solar storm" and "earth space storm". Solar storms summarize various explosive activities on the sun and the phenomenon that the solar wind changes as a result. The solar explosion or the violent release of the energy stored in the earth space itself makes the fields and particles in various regions of the earth space in a violent disturbance state, which becomes the earth space storm. These disastrous space weather events in near Earth space often directly affect human activities, and even have disastrous consequences. Access details
Human "dull", high-tech "sensitive"
"Generally speaking, it is difficult for human beings to feel the changes of space weather. At most, some life systems may have an impact, such as genetic diseases, but the probability is unclear." Wang Jinsong said, "If human beings want to feel the impact of space weather, they must rely on high-tech systems. In other words, space weather affects high-tech systems Technological system, high-tech system affects human life, so that humans can indirectly feel the impact of space weather. For example, if the power grid is cut off, people can feel it Of course, there is also a situation that will be more directly felt. For example, when the sun bursts strongly, the plane is not safe, and you will obviously feel the impact of space weather when you fly. But such events are relatively rare. Compared with the "dullness" of mankind to space weather, some technology systems widely used in the world are very "sensitive" to such events. "The impact of space weather is mainly on high-tech systems, so the more developed places are, the more seriously affected by space weather. For example, if space weather events occur now, Somalia will certainly have no impact, but the United States will suffer heavy losses." Access details 
Adequate awareness and attention will reduce the losses caused by space weather changes
Regrettably, this sensitive response to the technical system did not arouse sufficient understanding in most relevant industries. Speaking of this, Wang Jinsong was helpless. "We have a communication with related industries, but it is difficult for them to believe this. In the past, there were some events that we thought were caused by space weather, but people in related industries did not think it was the cause of space weather events. Since there was no very serious impact, most people did not believe or attach importance to space weather. This is very dangerous. In case of strong solar activity and other space weather events, it will suffer a lot. " If we can pay attention to this early warning and turn off the technical system during the time of space weather changes, a large number of equipment and economic losses can be avoided. "If the department that may be affected knows such knowledge in advance and has a plan, most of its losses can be avoided. So it is critical to know or not know." Access details
epilogue
-
At present, the sun has entered the 24th activity cycle, and the next five years will be the five years of increasing space weather disasters; At the same time, China's space industry, economy, society and national defense technology are developing rapidly, and their sensitivity to space weather is growing day by day. In contrast, the whole society has a serious lack of understanding of space weather, which will greatly restrict our understanding of the seriousness of space weather disasters and hinder our effective prevention, avoidance and mitigation of space weather disasters. Therefore, vigorously introducing and publicizing space weather disaster knowledge is actually the first step for space weather disaster prevention and mitigation, and also an effective way to popularize the public and reduce panic.
