My deep sea fishery

Of course, Antarctic temperatures can be so low, certainly there are many other reasons.

Antarctica such as high altitude, the air is relatively thin, and so, for these reasons that the average temperature in Antarctica is much lower than elsewhere.

And not only the Antarctic cold winds to blow sometimes terribly large.

Antarctica's terrain is very interesting, there are countless islands from the mainland, like a giant ice cream.

Intermediate mainland relatively high altitude above the cold air will fall, slide down along steep slopes between the mainland and the land along the coast, forming a strong wind.

Antarctic storm, I did not experience the people absolutely do not know, it's an average speed of seventy kilometers per hour, the fastest time even reach a per hundred meters.

What this does is equivalent, under the equivalent of heavy snow weather, the car on the highway to one hundred yards, then do not head out the window.

Some people think this is very exaggerated, in fact, this is a little to say.

Antarctica poor living environment, the area known as life.

Antarctica is not the entire, densely closest to the original inhabitants of Antarctica, New Zealand still waters.

But Antarctica is inhabited, every year, the world has another batch of polar expedition staff expedition to the Antarctic.

This is because Antarctica is the last continent to be discovered human, quite rich development and utilization of resources, and Antarctica unique climatic conditions and geographical environment but also by the astronomers of all ages.

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

Air humans actually hinder sight, although the human eye can not see the air, but it will affect the propagation of light, and extremely cold Antarctica, little moisture in the air, greatly reducing the spread of light obstacles, but also to protect the observation instrument metal parts from corrosion.

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

We'll know after the flow of heated air to form wind, but little Antarctica winter light, air heat more evenly, so little flow, which also contributes to precise observations of astronomers.

"Having said that, I have a doubt, Yang brother, you say what is the difference with the North Pole South Pole?" Fangyou group asked suddenly.

Chen Qingsheng Fang glanced at a group of friends, "no difference, you only need to remember that Antarctic fish, fish expensive than the Arctic on the line."

"Is that right?" Fangyou group quite puzzled.

Item Yang smiled, looked at Chen Qingsheng said:. "Can not say, Arctic sturgeon, the price is very high, if the species if the theory, then, can only be regarded as polar strengths and weaknesses."

"If you really want to say something, as long as you know what they are around, the North Hemisphere of the North is almost surrounded by land, and the Antarctic is a continent surrounded by the ocean, so the Arctic has Arctic bear. There is no penguin, and there is a penguin in the South Polar, but there is no Arctic bears. "Xiangyang smiled.

In fact, the Antarctic with the Arctic, the difference is still very big.

The Arctic has a large, the ocean covered by the ice, the surrounding of the North Pole is the permanent frozen soil without trees, which can be said to be located between the Arctic Circle and the North Pole.

If someone is standing on the Northern Path, no matter which direction, it is the south.

But in the North Pole, the human beings have no way to stand too long, because the North is covered with the sea ice that is constantly moving in the middle of the ocean.

If someone falls from the North Pole to the Arctic ocean, it will fall to the bottom of the sea, the average temperature in the winter on the water can be below zero 40 degrees Celsius, and the most cold temperature on the record is almost zero seven. Ten options are around.

In addition, there is an aboriginal person in the Arctic.

Although it is very difficult in the North Pole, it is still until today, some people still live in the Arctic.

Antarctic is the most southern continent in the earth, which contains the South Pole, the fifth largest continent on the earth, which is almost twice as large as Australia.

The mainland of the entire Antarctic is almost covered by ice and snow. There is a mile thick at the thickness. Some scientists say that the Antarctic ice is, most of them are from the urine of Penguins, but this statement is not universally recognized.

Xiangyang does not think this is correct, the reason is that the San Pole is really too much. If you rely on the urine of the penguin to form so many ice, you have to need endless years.

However, this statement is not unbound.

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

On average, the Antarctic is the most cold, the wind, the most dry, and the average altitude.

The dryness of the Antarctic can be said to be a desert.

There are only two hundred millimeters of rain along the coast, the less inland, if you rely on rainfall, it is difficult to form such a big glacier.

Speaking of this, Xiangyang suddenly laughed: "The South Pole is the coldest place in the world, the light of the Antarctic and Arctic should be almost the same, the heat dissipation of the Antarctic will be a little bit more than the Arctic, but the light is hot, very It is difficult to cause the average temperature difference between the Antarctic and the Arctic. "

"What is the reason?" Fang Friends asked.

Xiangyang Road: "The Arctic is the frozen ocean, and the seawater under the ice is much more warm than the frozen continent of the Antarctic, and the floating group will pass the temperature, which will make the Northern temperature will not be low to extreme."

In addition, the South Pole is far higher than the Antarctic.

In many cases, the temperature is accompanied by altitude.

It is such a truth like a lot of high mountains.

When I said that Xiangyang suddenly remembered a meaningful thing, "As far as I know, the world seems to have no plane throughout the Antarctic."

Fang Youqun doubtfully said: "Why is this? Is the plane flying over the Antarctic?"

"This is not, accompanied by the continuous improvement of human technology, the current human beings must fly over the polar region or relaxed, such as the Arctic, there are many aircraft to fly, Antarctic also have a lot of researchers, and take the plane to the Antarctic Or leave the South Pole. "Xiangyang replied.

So far, there is no airway through the Antarctic pole, or the main reason is not necessary, or there is no economic demand.

Antarctic has no human towns, stay away from other continents, from other two continents, do not need to pass through the Antarctic, no flight is willing to write around.

Secondly, for safety considerations.

According to ETOPS rules, the aircraft will not exceed 4 hours from the emergency airport when sailing in the sky.

How many emergency airports are there in the Antarctic?

In addition to McMimer, there is almost no emergency airport in Antarctic airport for emergency landing.
