Is there a sun in Antarctica, and for how long? When does the Southern Lights usually appear?

Yes, of course there is pulling.

The South Pole has the sun all year round (September to March of the following year), and there is sunshine 24 hours a day.

This is the polar day.

For the other half of the year, there is no sun (March-September), and it is in the dark 24 hours a day, which is the polar night.

The South Pole does not have a sun because the sun does not pass through the north and south poles, but only turns at the equator.

The South Pole also has a sun, and this is how the polar day or polar night comes, when the earth's revolution and the sun turn to a certain angle. In Antarctica, there will be polar daylight. The sun is shining day and night.

The most frequent occurrence of the Southern Aurora is in the ring belt area around 67 degrees of the Southern Magnetic Dimension, known as the Southern Aurora Zone. Aurora activity occurs almost every day in the Aurora Zone. The shape of the aurora is sometimes stable and sometimes continuous, and is generally in the form of a band, arc, curtain or emission.

Causes of the formation of the Southern Lights:The Sun is a large, red-hot ball of gas, in which various chemical elements are subjected to nuclear reactions, creating a powerful stream of charged particles, which are emitted from the Sun and shot into the surrounding space at great speed.

When this stream of charged particles hits into the thin high-altitude atmosphere on the periphery of the earth, it is attracted by the earth's magnetic field to the poles, and it violently impacts with the molecules of the thin gas, resulting in a luminescence phenomenon, which is called the aurora.

The Southern Lights generally occur during the polar night period.

Chinese name: Nan Aurora.

Foreign name: Aurora Australis

Alias: Aurora.

Property: Astronomical landscape.

Formation conditions: Charged particles collide with the magnetic field of the Earth's poles.

Location: High latitudes in the Arctic and Antarctic.

The South Aurora is a phenomenon that occurs when charged particles from the sun collide with the magnetic fields of the Earth's poles and discharge electricity in the sky. The Sun is a large, red-hot ball of gas, in which various chemical elements are subjected to nuclear reactions, creating a powerful stream of charged particles, which are emitted from the Sun and shot into the surrounding space at great speed. When this stream of charged particles hits into the thin high-altitude atmosphere on the periphery of the earth, it is attracted by the earth's magnetic field to the poles, and it violently impacts with the molecules of the thin gas, resulting in a luminous phenomenon, which is the aurora.

These colorful lights in the night sky are more common at high latitudes close to the North and South Poles. On a clear summer night, the aurora borealis can also be seen at low latitudes, far from the city lights. On the border between Canada and the United States, the Northern Lights can be seen many nights each year.

The Northern Lights or Southern Lights are as charming as the ceremonial flowers. The colors of the aurora range from light to dark, from green to red, and some of them resemble colored paper ribbons, some resemble fireworks, some resemble bows, and some resemble curtains ......

City lights and tall buildings on the horizon can get in the way, so the best sights of the aurora can only be seen in an open area in the countryside where there are no buildings. In Churchill City, Canada, the Northern Lights can be seen on 300 nights a year; In the state of Lurida, on average, it can only be seen about 4 times a year.

Most auroras occur 90---130 kilometers above the Earth. But some aurora lights are much higher. In 1959, a Northern Lights measured at an altitude of 160 kilometers and a width of more than 4,800 kilometers.

The aurora has been known for at least 2,000 years and has been the subject of many myths. In the early Middle Ages, Scandinavian pirates believed that the Aurora was a warrior galloping across the sky on horseback. In the Arctic, the Inuit believe that the aurora was created by the gods to light the way back to heaven for those who have recently died.

It depends on the latitude of the area, and the higher the latitude, the more frequent the aurora will be.

First of all, it is certain that the sun can shine as far as the North and South Poles.

Due to the existence of an angle between the ecliptic plane and the equatorial plane, it is about 23 degrees 26 minutes.

Causes the earth to always receive sunlight obliquely.

When the Northern Hemisphere is in summer, the direct sunlight is near the Tropic of Capricorn.

There will be parts of the Arctic Circle at the time of the Earth's rotation.

Sunlight is always received (of course, the sun is at a very low altitude).

On the contrary, many parts of Antarctica at this time have always been away from the sun.

So for a long time, I didn't see the sun all day long.

Similarly, when the Southern Hemisphere is in the summer, the Antarctic Circle has long daylight hours.

The Arctic Circle is going to be a little depressed.

Therefore, there will be polar day and night phenomena in the Arctic and Antarctic circles.

That is, there will be at least one day a year that is always day or night.

And as the dimension rises, at the North Pole and the South Pole.

There will be 6 months of day and 6 months of night.

Amen, I'm glad I don't have to live there.

Of course, it will be dark without the sun, and the north and south poles are only colder because they are far from the equator. Sometimes there are several consecutive days of polar day or polar night throughout the year.

There is no daylight at the polar night in Antarctica.

Polar night, also known as eternal night, is a phenomenon in which the sun is below the horizon in one day in the polar regions of the earth, that is, the night is 24 hours long. Both the North and South Poles have polar day and polar night, and there are roughly six consecutive months of polar day and six months of polar night in a year. During the polar night period of a sidereal month (about the sun), the moon is visible for half of the month (round and absent), and the moon is not visible for the other half of the month.

After the vernal equinox, the polar night will appear near the South Pole, and the polar night will become more and more widespread after that; It reaches its maximum on the summer solstice, and the boundary reaches the Antarctic Circle; After the summer solstice, the range of polar nights near the South Pole gradually decreased, and it shrank to 0 on the autumnal equinox. After the autumnal equinox, the polar night occurs near the North Pole, and the polar night near the North Pole becomes more and more extensive after that; Reaching its maximum on the winter solstice, the boundary reaches the Arctic Circle; After the winter solstice, the polar night near the North Pole gradually decreases, reaching 0 on the vernal equinox.

Antarctica has no daylight at the time of the polar night.

When the sun is shining directly on the Tropic of Capricorn. That is, the day of the summer solstice here in China

Antarctica has strong sunlight. Mainly due to the destruction of the ozone layer by human emissions of HCFCs, the cold climate in the Antarctic region is not significant, so that the stratosphere is closer to the ground than other parts of the earth, and is also the first to be damaged by HCFCs, so the Antarctic ozone layer has less light absorption and stronger light. <

Antarctica has strong sunlight. Mainly due to the destruction of the ozone layer by human emissions of HCFCs, the cold climate in the Antarctic region and the lack of convection in the Antarctic region, which makes the stratosphere more compact and close to the ground than other parts of the earth, and is also the first to be damaged by HCFCs, so the Antarctic ozone layer absorbs less light and has strong light.

Light Intensity: Light intensity is a physical term that refers to the luminous flux of visible light received per unit area. Abbreviated as illuminance, the unit is lux.

It is used to indicate the intensity of the light and the amount of illumination of the object's surface area. In photometry, "luminosity" is the density of luminous intensity in a specified direction, but it is often misunderstood as illuminance. The SI unit of luminosity is the candlelight received per square meter (Candela in Chinese mainland, Hong Kong and Macao).

Light intensity has a great impact on the photosynthesis of living things. Altitude measurements can be made by means of a lux meter.

First, the ozone layer is located in the stratosphere, and the strong ultraviolet radiation in the Antarctic region is mainly due to the destruction of the ozone layer by human emissions of HCFCs.

In Antarctica, the cold climate and insignificant convection make the stratosphere closer to the surface than the rest of the planet, and it is also the first to be damaged by HCFCs.

And it can't help but be in the Antarctic region, and in the Arctic region ultraviolet radiation is also very serious.

There is no direct sunlight, but there will be a polar day. The point of direct sunlight will only move between the Tropic of Capricorn.

No, the direct point of the sun is only within the Tropic of Capricorn.
