What measures should we take to prevent the adverse effects of solar activity on the planet

The measures that can be used to prevent the adverse effects of solar activity on the Earth are limited and costly. First, satellites can be used to block solar radiation.

A lot of satellites are needed, and the cost is conceivable); Second, civilian satellites should be equipped with radiation protection devices similar to those of military satellites; Third, solar activity mainly affects electronic equipment and power supply facilities, so the current capacity of such equipment and facilities should be increased. In addition, some scholars envisage placing the soil of the Moon between the Earth and the Sun to block solar radiation (Lunar Soil.

can effectively block solar radiation). But these are only assumptions, and it is difficult to put them into practice.

Do a good job of astronomical observations, grasp the cycle of solar activity, and reduce the launch of space satellites during peak periods.

The effects of solar activity on the earth are: 1. Disturb the earth's atmosphere, so that the radio short-wave communication on the ground will be affected, and there will even be a short interruption. 2. High-energy charged particles disturb the earth's magnetic field, producing a "magnetic storm" phenomenon, which makes the magnetic needle vibrate violently and cannot indicate the direction correctly.

3. Auroras will occur when a stream of high-energy charged particles rushes into the high-altitude atmosphere of the polar regions at high speed. 4. Cause natural disasters, such as floods and droughts.

Solar activity is the general term for all the active phenomena in the solar atmosphere. There are mainly sunspots, light spots, spectral spots, flares, solar and coronal transient events, etc. Caused by electromagnetic processes in the Sun's atmosphere.

The time is strong and sometimes weak, and the average is on a yearly cycle. The Sun is a largely stable star. Its total amount of radiation, most of which is visible, varies very little.

However, its outer atmosphere is in local intense motion due to the domination of the Sun's magnetic field. When observing the sun's photosphere with white light, once a small black spot appears, you can see some small areas around it that are brighter than the quiet light sphere, called light spots. A spot is a bright spot on a photosphere that often appears on the edge of the sun ring, indicating that it exists in the upper layer of the photosphere and may be a hotter air mass on the photosphere.

The light spots generally surround the sunspots, and they have a close relationship with the sunspots.

The number of sunspots changes have a significant impact on the precipitation of the earth's atmosphere, flares will affect the ionosphere in the earth's atmosphere, interfere with wireless communications, and produce magnetic storms when strong. The maximum solar radiation on the equator is around the vernal and autumnal equinoxes, and the sun shines directly on the equator during the spring and autumn equinoxes, and the solar height is the highest at noon, and the radiation is the strongest. The minimum is at the summer and winter solstices, when the direct point is farthest from the equator, the height of the sun at noon is the lowest, and the radiation is weakest (but it is also very strong relative to other latitudes of the Earth).

Under normal circumstances, a protective "magnetic bubble" (a "magnetic bubble" formed by the expansion of the sun's land-based magnetic field to the edge of the solar system) around the solar system protects us from interstellar dust, but during the inversion of the sun's two magnetic poles, this "magnetic bubble" disappears for a period of time. Astronomers believe that the amount of interstellar dust that falls on Earth every day during the disappearance of the "magnetic bubble" will increase to 40,000 tons. While this won't hurt, we may have a chance to see more faint meteors streaked across the sky.

The effects of solar activity on the Earth are:

1. Disturb the earth's atmosphere, so that the radio short-wave communication on the ground will be affected by the shadow beam, and even there will be a short interruption.

2. High-energy charged particles disturb the earth's magnetic field, producing a "magnetic storm" phenomenon, which makes the magnetic needle vibrate violently and cannot indicate the direction correctly.

3. When the stream of high-energy charged bond particles rushes into the high-altitude atmosphere of the polar regions at high speed, the aurora phenomenon will be generated.

4. Triggering natural disasters.

For example, floods and droughts. Oak Bright Row.

Solar activity is a general term for all active phenomena in the solar atmosphere, mainly sunspots.

Flares, flares, suns, etc. It is caused by electromagnetic processes in the solar atmosphere, which is sometimes intense and sometimes weak, with an average cycle of 11 years. The sun, which is in a period of intense activity, emits a large amount of ultraviolet light.

X-rays, particle streams and intense radio waves, which often cause phenomena such as auroras, magnetic storms and ionospheric disturbances on Earth.

1) Disrupt the ionosphere and affect radio shortwave communications.

2) The phenomenon of "magnetic storm" is generated, and the magnetic needle cannot indicate the correct direction of the limb.

3) Auroras form in the Arctic and Antarctic regions.

4) Affect the climate, hydrology, reed dust geology and human life on the earth.

5) Taipeizhen Chanyang activities endanger interstellar navigation.
