What will be the impact of the geomagnetic storm on our life in 2018
4hw.com.cn: Recently, according to foreign media reports, authoritative organizations have detected that: the earth will be affected by ten magnetic storms in 2018, four of which will be giant ones, which sounds very frightening, so what impact will magnetic storms have on our lives? Let's have a look.
According to materials mastered by satellite news agency: 'it is expected that 20-35 magnetic storms will occur in 2018, including large and extra large storms. The probability of occurrence of super strong magnetic storm is about 5%. '
NASA's Solar Observing Satellite, the Solar Dynamics Observatory (SDO), has captured two large black spots on the sun's surface. These large black spots, also known as "coronal holes," are caused by the sun's surface magnetic particles, blown out of space by the solar wind, resulting in some areas showing darker colors. This is the second time that a large area of 'coronal hole' has appeared on the sun's surface after SDO satellite captured a huge black area near the sun's South Pole in January.
It is pointed out that the high energy electron flux will increase regularly, some of which will last for five days or more, which may have a negative impact on the electronic instruments of geosynchronous satellites and low orbit satellites. It is also stressed in the forecast: 'the increase of electron flux may become the most dangerous factor for space weather next year. '
What are the effects of magnetic storms on our lives
In addition, three days before the storm, the earth's geomagnetic atmosphere will change significantly, which may affect the power grid and hinder communication.
So it is possible to cut off the network.
Fortunately, such destruction is not common. Geomagnetic storms are now more destructive than in the past, because we rely more on technological systems that can be affected by current and high-energy particles in the magnetosphere.
The largest geomagnetic storm ever recorded was the Carrington incident in 1859, which resulted in the failure of telegraph systems in Europe and North America.
However, due to the fact that there was no satellite, radio communication and modern power transmission network at that time, mainly relying on steam engine and labor, this incident did not bring about too serious disaster.
The effects on human health vary from person to person. Scientists have proved that the impact of magnetic storms on human health, there is a kind of weather dependent people, they will feel uncomfortable and headache at this time.
But don't be nervous. For people with obvious physical reactions, doctors suggest drinking more liquid to protect themselves from harm.
'try to sleep. Don't overload your body with excess coffee, alcohol, and plenty of food. '
However, from an aesthetic point of view, one of the positive aspects of geomagnetic storms is that perhaps aurora can be seen.
Although the Carrington incident in 1859 disrupted the whole telegraph system in Europe and North America, it saw aurora all over the world.
The miners at the local gold mine in Rockies were woken up, thinking it was morning, and began to prepare breakfast. People in the northeast of the United States could read newspapers at night through aurora.
According to some reports, scientists estimate that the magnetic field protecting the earth has weakened by about 15% in the past 200 years. They think it may be a sign that the earth's magnetic poles may turn over completely.
It is reported that this invisible protective shell has existed for 4.2 billion years, or shortly after the formation of the earth. If there is no magnetic field, the flow of charged particles from the sun - the solar wind will erode the earth's atmosphere and ocean, so the magnetic field makes life possible on earth.
Daniel Beck, director of the atmospheric and space physics laboratory at the University of Colorado, said the reversal could lead to 'non habitability' in some areas.
