Jupiter is the largest of the eight planets in the solar system (its radius is 1 1 times that of the earth, and its volume is 132 1 times that of the earth), and it is also the planet with the fastest rotation (the rotation period at the equator is 9 hours, 50 minutes and 30 seconds, and the polar rotation is about 5 minutes slower). The magnetic field intensity at the equator is 4.2 gauss (0.42mT), and at the polar regions it is 10 to 14 gauss. The temperature is about 200 degrees, and the temperature difference between the equator and the poles is no more than 3 degrees. There are 17 bright rings and dark rings on the surface of Jupiter, and there are 79 satellites. The distances between the larger satellites Io, Europa, Ganymede and Callisto conform to Titius-Bode law, and the dynamic relationship of revolution is fixed at 1:2:4:8.

The most striking thing about Jupiter is the famous Great Red Spot at 23 degrees south latitude. There is a dark low pressure belt running slowly from east to west between the equatorial tropical high pressure belt and the south temperate high pressure belt. The Great Red Spot is located between this dark low pressure area and the high pressure area in the south temperate zone. The airflow in the south moves eastward, and the airflow in the north slowly moves westward, forming an anticyclone. The Great Red Spot is about 25,000 kilometers long from east to west, with a north-south span of12,000 kilometers. Yunding is 8 kilometers higher than the surrounding clouds and rotates counterclockwise every 6 Earth Days.

There is a nucleus about a few hundred kilometers away from the center of the Great Red Spot, which rotates slowly clockwise in the counterclockwise vortex and seems to be stationary. The temperature in the orange-red area is three to four degrees Celsius higher than that in the surrounding area. Jupiter's highest altitude temperature is also above the Great Red Spot.

Scientists have different opinions about what the Great Red Spot is. Some people say that the Great Red Spot is a typhoon similar to an anticyclone. Some say that according to the data sent back by Jupiter probe, it is found that the internal temperature of Jupiter is very high, and the heat emitted is 2.5 times that absorbed from the sun. It is speculated that the Great Red Spot may be the place where the columnar vortex with the highest temperature inside Jupiter continuously ejects outward, similar to the volcanic eruption on the earth.

There can only be one truth. Is the Great Red Spot a typhoon or a volcanic eruption?

Let's analyze it according to the data.

1, the great red spot rotates in the opposite direction. The airflow on the north side moves slowly to the west, and the airflow on the south side moves eastward, which seems to be an anticyclone. This is similar to a typhoon. But there is an eye in the center of the typhoon, that is, there is no material space. The Great Red Spot has no eyes, just a whirlpool. It is hard to say that the Great Red Spot is a typhoon.

2. The red substance of the Great Red Spot is very different from its surroundings, which is obviously not caused by typhoon.

3. The temperature in the orange-red area of the Great Red Spot is three to four degrees Celsius higher than that in the surrounding area, and the temperature above the Great Red Spot is also significantly higher than that in the surrounding area. Scientists say? This temperature difference is enough to cause the center to cycle clockwise. ? I think the temperature above the Great Red Spot is obviously higher than that around it, indicating that the heat source is inside Jupiter.

4. The Great Red Spot is synchronized with Jupiter's rotation. The atmosphere on Jupiter's surface flows eastward, and the Great Red Spot does not move. The airflow from west to east in the northern equatorial high pressure zone did not surrender to the Great Red Spot, indicating that the Great Red Spot was very tenacious, and the small red spot and white spot on the west side gradually approached the Great Red Spot, indicating that the Great Red Spot remained motionless. Obviously, the Great Red Spot is deep-rooted and powerful, and it is not afraid of strong winds.

5. The core of the Great Red Spot seems to turn clockwise. Explain that the nucleus and the outer side are not the same system.

From this analysis, the Great Red Spot is not a typhoon, but a volcanic eruption, a high-speed, sustained and tenacious volcanic eruption.

Generally speaking, volcanic eruption should fall back, but Jupiter's volcanic eruption is too strong, and the high-temperature gas spewed out is wrapped in a thick atmosphere, exposing only one head and a rotating red warm head. Therefore, the temperature above the great red spot is higher than that around it. Because the Great Red Spot is a volcanic eruption, it rotates in the same direction as Jupiter, just like a hurricane in the southern hemisphere of the earth. As for the anticyclone, it is just two opposite air currents on Jupiter's surface rubbing around the Great Red Spot. If you look deeper, you will find that the Great Red Spot is still the mainstay. Because the Great Red Spot is not a cyclone, there is no eye and no spiral arms. It is precisely because the Great Red Spot is not a cyclone that we review those passing cyclones from high altitude.

Of course, you can also say that the Great Red Spot is not a volcanic eruption, but a gas explosion. Because most of what we observe is gas.

Some scientists warn that Jupiter's Great Red Spot may disappear within 20 years, because it is gradually shrinking now. There's no need to worry. Jupiter's great red spot will not disappear immediately. Because the intense friction inside Jupiter will generate a lot of heat. This heat needs to be released. Why rush to close the released window?
