My Deep-sea Fishery

Of course, there must be many other reasons why the temperature in Antarctica can be so low.

For example, the altitude of Antarctica is high, the air is relatively thin, etc. These reasons make the average temperature of Antarctica much lower than other places.

Moreover, Antarctica is not only cold, but sometimes the wind is terribly strong.

The terrain of Antarctica is very interesting. It is composed of a continent and countless islands, like a huge ice cream.

The mainland in the middle is relatively high above sea level, and the air above will drop when it gets cold, and slide down the steep slope between the mainland and the coast, forming strong winds.

Those who have never experienced the storm in Antarctica will never know it. Its average speed reaches 70 kilometers per hour, and at its fastest it can even reach 100 meters per second.

What is this equivalent to, the equivalent of driving a hundred yards on the highway in heavy snow and then sticking your head out of the window.

Some people think this statement is exaggerated, but in fact it is an understatement.

The living environment in Antarctica is extremely poor, known as the forbidden area for life.

The entire Antarctica has no aborigines, and the closest people to Antarctica are still in the waters of New Zealand.

However, there are residents in Antarctica. Every year, groups of polar expedition personnel from all over the world go to Antarctica to explore.

This is because Antarctica is the last continent to be discovered by humans, and the resources that can be developed and utilized are quite rich, and Antarctica's unique climatic conditions and geographical environment are also favored by astronomers.

Although the air in Antarctica is thin, it is just conducive to the observation of space.

The air actually hinders the sight of human beings. Although the human eye cannot see the air, it will affect the transmission of light. Antarctica is extremely cold, and there is very little water vapor in the air, which greatly reduces the transmission of light. It can also protect the metal parts of the observation instrument from corrosion.

In addition, Antarctica has less air movement, which is also conducive to astronomical observations.

We know that when the air is heated, it will flow and form wind, but Antarctica has less sunlight in winter and the air heat is more uniform, so there is less flow, which also helps astronomers to make accurate observations.

"Speaking of which, I have a doubt, Brother Yang, what do you think is the difference between the South Pole and the North Pole?" Fang Youqun asked suddenly.

Chen Qingsheng glanced at Fang Youqun, "There is no difference, you just need to remember that fish from the Antarctic are more expensive than fish from the North Pole."

"Is that so?" Fang Youqun asked in confusion.

Xiang Yang smiled, looked at Chen Qingsheng and said, "You can't say that, the price of sturgeon in the North Pole is also very high. If we talk about the types of creatures, the North and South Pole can only be regarded as having their own merits."

"If you really want to tell the difference, as long as you know what is around them, the North Pole is in the northern hemisphere of the earth and is an ocean almost surrounded by land, while the Antarctic is a continent that is almost surrounded by ocean, so there are polar bears in the North Pole There are no penguins, there are penguins in Antarctica but no polar bears." Xiang Yang said with a smile.

In fact, there is a big difference between the Antarctic and the North Pole.

There is a large, snow-covered ocean in the North Pole, surrounded by treeless permafrost, this place can be said to be located between the Arctic Circle and the North Pole.

If someone is standing on the North Pole, no matter which direction that person is looking, it is south.

But at the North Pole, humans can't stand for long because the North Pole is covered by moving sea ice in the middle of the ocean.

If someone falls from the North Pole to the Arctic ocean, they will fall directly to the bottom of the sea at a depth of 14,000 feet. The average winter temperature on the surface of the water can be lower than minus forty degrees Celsius, and the coldest temperature on record is almost minus seven. About ten degrees Celsius.

In addition, there are indigenous peoples in the Arctic.

Although life in the Arctic is difficult, there are still people living in the Arctic to this day.

Antarctica is the southernmost continent on Earth, containing the South Pole, and is the fifth largest continent on Earth, almost twice the size of Australia.

The entire continent of Antarctica is almost covered by ice and snow, at least one mile thick. Some scientists say that most of the ice and snow in Antarctica actually come from penguin urine, but this statement has not been generally recognized.

Xiang Yang also doesn't think this statement is correct, because there is really too much ice and snow in Antarctica, and it would take endless years to form so much ice and snow with penguin urine.

However, this claim is not without basis.

The living environment in Antarctica is said to be the most extreme in the world.

On average, Antarctica is the coldest, windiest, driest, and highest average altitude in the world.

The dryness of Antarctica can be said to be a desert.

There is only two hundred millimeters of rainfall along the coast, and it gets less and less as you go inland. If you rely on rainfall, it is difficult to form such a large glacier.

Speaking of this, Xiang Yang suddenly smiled and said: "The Antarctic is the coldest place in the world. The light in the Antarctic and the North Pole should be similar. The heat dissipation in the Antarctic may be slightly faster than that in the North Pole. It is difficult to cause such a large difference in average temperature between the Antarctic and the Arctic."

"Then why?" Fang Youqun asked.

Xiang Yangdao: "The North Pole is a frozen ocean. The sea water under the ice is much warmer than the frozen Antarctic continent. The ice floes will transfer the temperature, which will keep the temperature in the North Pole from being extremely low."

In addition, it is also true that the altitude of Antarctica is much higher than that of Antarctica.

In many cases, the temperature decreases with altitude.

There is snow on the top of many high mountains, which is the reason.

Speaking of this, Xiang Yang suddenly thought of an interesting thing, "As far as I know, there doesn't seem to be any plane in the world that has crossed the entire Antarctic."

Fang Youqun wondered, "Why? Is it because planes can't fly over Antarctica?"

"That's not true. With the continuous advancement of human science and technology, it is still very easy for human beings to fly over the polar regions. For example, there are many planes flying over the North Pole. There are also many scientific researchers in the South Pole. They take planes to the South Pole. Or leave Antarctica." Xiang Yang replied.

The main reason why no plane has crossed the Antarctic so far is that it is unnecessary, or in other words, there is no economic demand.

There are no human cities and towns in Antarctica, and it is far away from other continents. There is no need to pass through Antarctica to travel between any two continents, and no flight is willing to detour for nothing.

The second is for safety considerations.

According to ETOPS rules, when the aircraft is in the sky, it must not be more than 4 hours away from the emergency airport.

And how many emergency airports are there in Antarctica?

Except for McMurdo, there are almost no emergency airports in Antarctica for planes to make emergency landings.
