My Deep-sea Fishery

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

For example, Antarctica's high altitude, relatively thin air, etc., these reasons make Antarctica's average temperature much lower than other places.

And the Antarctic is not only cold, the wind is sometimes terribly big.

The terrain of Antarctica is very interesting. It is made up of the mainland and countless islands, just like a huge ice cream.

The continental area in the middle has a relatively high altitude, and the air above it will drop when it is cold, and it will slide down the steep **** between the mainland and the land along the coast, forming strong winds.

People who have never experienced the storm in Antarctica are absolutely unaware of it. Its average speed reaches 70 kilometers per hour, and it can even reach 100 meters per second at the fastest.

What is this equivalent to? It is equivalent to driving for a hundred yards on the highway in a snowy weather, and then not sticking out the window with your head.

Some people think this statement is very exaggerated, but in fact it is still a little bit smaller.

The living environment in Antarctica is extremely poor and it is known as a restricted area of ​​life.

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

However, Antarctica has inhabitants. Every year, groups of polar expeditioners from all over the world go to Antarctica for expeditions.

This is because Antarctica is the last continent discovered by humans, and the resources available for development are quite rich, and Antarctica's unique climate 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 is actually a hindrance to human sight. Although the human eye cannot see the air, it will affect the spread of light. Antarctica is extremely cold and there is very little water vapor in the air, which greatly reduces the spread of light. Obstruction can also protect the metal part of the observation instrument from corrosion.

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

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

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

Chen Qingsheng glanced at Fang Youqun, "It makes no difference, you just need to remember that fish in the Antarctic are more expensive than those in the Arctic."

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

Xiang Yang smiled and looked at Chen Qingsheng and said, "It can't be said that the price of sturgeon in the Arctic is also very high. If it is concerned with biological species, the North and the South 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, which is an ocean almost surrounded by land, and the South Pole is a continent almost surrounded by the ocean, so there are polar bears in the North Pole. And there are no penguins, there are penguins in Antarctica but no polar bears." Xiang Yang said with a smile.

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

The North Pole has a large ocean covered with ice and snow. Around the North Pole is permafrost without trees. This place can be said to be located between the Arctic Circle and the North Pole.

If someone stands on the North Pole, no matter which direction that person looks in, it is always south.

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

If someone falls from the North Pole to the North Pole ocean, they will fall directly to the seafloor as deep as 14,000 feet. The average winter temperature on the water surface can be below minus 40 degrees Celsius, and the coldest temperature on record is almost minus seven. About ten degrees Celsius.

In addition, there are aboriginal people in the Arctic.

Although life in the Arctic is difficult, people still live in the Arctic to this day.

Antarctica is the southernmost continent on the earth. It contains the South Pole and is the fifth largest continent on the 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 universally recognized.

Xiang Yang also doesn't think this statement is correct. The reason is that there is too much ice and snow in Antarctica. If so much ice and snow are formed by penguin urine, it will take endless years.

However, this statement is not unfounded.

The living environment in Antarctica is one of the most extreme in the world.

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

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

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

Speaking of this, Xiang Yang suddenly smiled and said: "The South Pole is the coldest place in the world. The light from the South Pole and the North Pole should be about the same. The South Pole may dissipate heat slightly faster than the North Pole, but the heat dissipation of light is faster. It is difficult to cause the difference in average temperature between the Antarctic and the Arctic so much."

"What else is there?" Fang Youqun asked.

Xiang Yang said: "The Arctic is a frozen ocean. The sea under the ice layer is much warmer than the frozen continent of Antarctica. Floes will transmit temperature, which will keep the temperature of the Arctic from being too low to extremes."

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 tops of many high mountains. This is the reason.

Speaking of this, Xiang Yang suddenly remembered an interesting thing, "As far as I know, it seems that no plane in the world has crossed the entire Antarctic."

Fang Youqun wondered: "Why is this? Is the plane unable to fly over Antarctica?"

"This is not true. With the continuous advancement of human science and technology, it is still very easy for humans to fly planes over polar regions. For example, many planes fly over the North Pole, and many in the South Pole. Scientific researchers, take a plane to reach the South Pole or leave the South Pole." Xiang Yang replied.

So far, no plane has crossed the Antarctic, the main reason is that it is unnecessary, or that there is no economic demand.

There are no human towns in Antarctica, and it is far from other continents. From any two other continents, there is no need to pass through Antarctica, and no flights are willing to make a detour.

The second is for safety considerations.

According to the rules, when the plane is sailing 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 is almost no emergency airport for planes to land in Antarctica.
