Recently, another strong solar flare erupted , and the entire activity cycle peaked at 4:25 ET on October 2. For us, the word flare is not unfamiliar with it. When we first started learning geography, we knew the existence of flares.
Flares are essentially a manifestation of solar motion . The local surface of the sun suddenly releases energy on a large scale, resulting in a local temperature increase and the particle radiation becomes stronger. The whole process is flares. According to the peak flow of the solar X-ray, we usually divide the flare into A, B, C, M, and X, and the energy released increases in sequence.
And our solar motion has cycles, generally 11 years as the cycle. Currently, we are in the 25th active cycle of the sun, and the explosion of solar activity is increasing, and we are close to the huge year of solar activity. In one cycle, flare levels of X10 or above occur about 10 times, flares of X will occur about 200 times, while M-level flares are about 200 times. For people, flares are actually a bit rare and strange.
According to NASA's prediction, this solar activity cycle is expected to reach a maximum value around 2025. In April this year, a level X2.2 flare broke out, which was even more violent than this one.
The sun's movement this year is indeed more active than in previous years.
The impact of solar motion on the earth's climate
The sun's motion, such as frequent flares, release greater radiation and energy. Will it make the earth hot?
From a scientific point of view, when the sun is more active, the ultraviolet radiation increases a lot, and a chemical reaction occurs in stratosphere , forming ozone . According to relevant measurement results, solar activity will affect extreme weather to some extent, such as extreme high or low temperatures.
In terms of this flare outbreak, will the earth's climate undergo any changes? The radiation of the sun does not directly affect the earth's ground. It first passes through our atmosphere. Our atmosphere plays a very good protective role. Even when the solar activity is at its highest, the energy the Earth receives from the Sun is only 0.1% higher than the average. Therefore, the impact of an solar flare explosion on the earth's temperature can be said to be minimal and completely negligible.
Will the sun's movement affect this cold wave?
Since the beginning of the holiday, many people have enjoyed the cliff-like reduction of temperature. They are wearing short-sleeved clothes, and suddenly a cold wave comes. On the one hand, many places across the country began to break the high temperature in October, while on the other hand, the temperature began to drop and entered the autumn mode.
But according to our analysis above, the movement of the sun will not provide more energy to the earth. Even if the high-level solar flare bursts, the temperature on the earth will not increase significantly. How exactly does flares affect our lives? Flares are not rare, but they occur more than 100 million kilometers away from our earth. How can we sense flares? It can even be said that if there were no scientific means, such as the Fengyun-3 E-Star in our country, which can monitor the occurrence of flares, many people would not even know that flares are coming. The solar flare has a greater impact on wireless communication , near-Earth satellites and space station . In general, the most important impact of solar flares is the bad signal on the earth. Especially, it has the greatest impact on short-wave communication. If the band of the solar flare coincides with the band of television broadcasts, then the noise will be very high. Secondly, it has a greater impact on electronic devices, and may even affect aviation operations. Some activities that require relying on communications are also greatly affected. Therefore, solar flares generally have an impact on some professionals with relatively high technical requirements. It is difficult to feel solar flares in our daily lives. After all, this is a common natural phenomenon and humans have no way to avoid it. Follow Maxwell's science and take you through the latest and most interesting scientific trends.
