What are the effects of sunspots on the Earth?

The close relationship between the earth and the sun is self-evident, the sun is the basis of the existence of life on the earth, the source of light and heat on the earth, no matter what conditions and changes it occurs, it will have a very important impact on the earth. Sunspots are a very active phenomenon of matter on the sun, so the impact on the earth is also particularly obvious.

Therefore, when there are large groups of sunspots on the sun, the earth is also deeply affected by them: the compass will suddenly shake wildly, and it will not be able to indicate the direction correctly; Pigeons are no longer as good at knowing the road as they usually are; Radio communications were also severely hampered, even abruptly interrupted for a while. These effects are negative, and these anomalies will bring us great harm, such as airplanes, ships, and television and faxes that cannot work properly.

Moreover, sunspots can also cause changes in the Earth's climate. A Swiss astronomer discovered more than 100 years ago that when there are many sunspots, the Earth's climate is mostly dry and agricultural harvests fail; However, when there are few sunspots, the climate is more humid, and even heavy rain occurs. In China, the famous scientist Zhu Kezhen also researched it and recorded it in ancient books, but where there are more records of particularly cold winters in China, the century with the most records of sunspots is also the century with the most records.

When some people count the changes in rainfall in some areas, they find that there is a pattern in the change of rainfall, which is repeated every 11 years, and this is probably also related to the increase or decrease in the number of sunspots.

In addition, scientists who studied ** found that the number of sunspots is also directly proportional to the number of sunspots on Earth. And the number of times is also cyclical for about 11 years.

Botanists have also found that the growth of trees also varies with the change of sunspots, with the year with more sunspots growing faster and the opposite growing slower, and also with an 11-year cycle.

Not only that, human beings themselves cannot escape the influence of sunspots, and our bodies also have a lot to do with sunspots, and the changes in the number of white blood cells in human blood also have a cycle of 11 years.

The sun is the source of light and heat on Earth, and its every move has an impact on the Earth. Sunspots are an intensely active phenomenon on the Sun, and their impact on the Earth is also obvious. Scientists have found that when sunspots are active, they can have an effect on the Earth's magnetic field, affecting radio communications and interfering with the work of satellites and spacecraft.

The effects of sunspots on the Earth are:

1. The compass will tremble, or it may not be able to point the direction correctly.

2. Cause some creatures to lose their sense of direction, such as pigeons.

3. Cause some interference of modern tools, such as radio obstruction.

4. It leads to the drying out of the earth's climate and the reduction of crop survival.

5. The movement of sunspots is very low or reduced, which will lead to changes in the earth's climate, such as the climate becoming humid and frequent storms.

A "sunspot" is a dark area formed by the sun, so dark that the sun's rays cannot illuminate it. And this dark area is where the magnetic field is formed after the episode.

And it can be said that "sunspots" are the only most obvious phenomenon of the sun, and you may not believe it, but this is according to the research of scientists, in fact, a medium-sized "sunspot" produced in the sun is about the same size as the earth!

Long-term observations by astronomers have shown that when the intensity of "sunspots" is larger, other phenomena about the sun become more frequent. After the intense movement of the sunspot, a spot will appear in the nearby light sphere, and a spectral spot will appear in the sky above the sunspot, and there may also be a sunspot during the period.

During a total eclipse of the sun, the sun is surrounded by a red ring that usually erupts in the shape of a tongue. Therefore, it is called the sun by scientists, and the sun is one of the signs of solar activity.

Sunspots have an impact on the earth, mainly in the following ways:

1. Influence solar wind:

Sunspots refer to dark spots on the surface of the sun, and their formation is related to the solar cycle. The magnetic field in the sunspot region is stronger than in the surrounding area, causing changes in the speed and density of the solar wind, which affects the Earth's environment.

2. Triggering solar flares and coronal mass ejections

Sunspots are one of the manifestations of solar activity, and they are often closely associated with phenomena such as solar flares and coronal mass ejections. Solar flare bonding is an intense burst of radiation from the surface of the Sun, which releases large amounts of energy and matter, including high-energy charged particles.

Coronal mass ejections, on the other hand, refer to the giant gas bubbles produced on the surface of the sun, which will bring more serious solar wind and magnetic storm effects, and have a greater impact on the environment such as the earth's magnetosphere and ionosphere.

3. Affect the earth's weather

The activity cycle of sunspots is also related to the changes in the Earth's weather. When the sunspots are most frequent, the Earth's climate will also show certain regular changes, such as increased snowfall in the Antarctic region and more summer storms. In addition, the activity of sunspots can also cause changes in the Earth's magnetosphere, leading to errors in weather forecasts and other aspects.

4. Impact on communication and satellite navigation systems:

When sunspots are violently active, they will produce strong effects such as high-energy ionizing radiation and electromagnetic interference, which will interfere with and destroy systems such as communications and satellite navigation. For example, during a strong solar flare in November 2003, a dramatic increase in ionospheric density caused the global GPS system to be interrupted for about 30 minutes.

In summary, the impact of sunspots on the earth is mainly manifested in the influence of solar wind, the triggering of solar flares and coronal mass ejections, the impact of the earth's weather, and the impact on communication and satellite navigation systems. Today, when human society is highly dependent on science and technology and space technology, the impact of sunspot activities on human society has received more and more attention, and relevant research and monitoring work needs to be strengthened.
