Is China s Antarctica frozen? 30

Antarctica is not yet a country, and some countries should have base stations on it. It's icy and snowy.

It's dripping, but it's getting warmer, and the Antarctic and the North Pole are about to disappear!!

1.The vast majority of the Antarctic region is within the Antarctic Circle, and the latitude is very high, so the amount of solar radiation is smaller2The Antarctic region has the highest average altitude in the world, so the altitude is higher and the temperature is lower by 3

The landform of the Antarctic region is dominated by glacial ice sheets, and the mirror reflection is strong, so a considerable part of the only solar radiation is reflected.

4.The Antarctic region is surrounded by westerly drifts (cold currents) and Antarctic circulation (cold currents), which block heat exchange between nearby seas and lower latitudes, exacerbating the coldness.

5.The Antarctic region is inaccessible, with little human activity, no industrialization, and no heat island effect.

6.The vast majority of the Antarctic region is located in the Antarctic Circle, and there is a polar night phenomenon, and there is almost no solar radiation during the polar night season, which exacerbates the cold effect.

7.The air in the Antarctic region is thin and the atmospheric reverse radiation effect is weak, so the insulation effect of the atmosphere is poor.

The latitude is the highest, there are no continents to block it, westerly winds drift, so it is colder than the Arctic.

It is generally said that the coldest places on Earth are in the top of the mountains and in the polar regions. But it is also different in the northern and southern hemispheres and in different regions.

The coldest place in Asia, neither at the North Pole nor in the Arctic Circle, but in Oymyakon in eastern Siberia, at 63° north latitude. There, in February 1885, it was officially awarded the title of "Cold Pole" in the Northern Hemisphere, and in January 1964 it broke the previous record with a low temperature of -71.

Why is the "cold pole" of the Northern Hemisphere not at the pole, but about 27 latitudes to the south? This is because Oymyakon is a place where the Siberian cold high has been entrenched for a long time, and the surrounding terrain is a basin, which promotes the accumulation of cold air and radiative cooling. The Arctic Circle, on the other hand, is the Arctic Ocean, and although it is covered with sea ice, there is still heat transmitted from under the ice to the lower air above the ice, so that the temperature is not as low as that of Oymyakon.

In North America, because the land area is not as large as that of Eurasia and the mountains are running north-south, the cold high pressure there is not as strong as in Asia, and it can stretch southward unhindered, resulting in a slightly less cold winter in North America than in Asia. At the same time, due to the climate regulation of the Arctic Ocean, the coldest places are not along the Arctic Ocean coast at higher latitudes, but in the valleys of the inland where cold air tends to accumulate slightly south. For example, the Yukon Valley has an extreme minimum temperature of -63.

In Europe, the coldest place is, of course, Greenland. It has a high latitude, high terrain, ice covered ground, and a very cold climate all year round, with an extreme minimum temperature of -65 in the Esmit region.

The coldest place is not in the Northern Hemisphere, but in Antarctica, the Southern Hemisphere. It is covered with a thick layer of snow and ice all year round, with an average snow thickness of 1,700 meters, the energy from the sun3 4 is reflected back into the air, and the temperature on the ground is very low. On August 24, 1960, the temperature was measured.

It can be seen that the "cold pole" on the earth should be on the Antarctic continent.

1.Ice shelves are large areas of fixed ice floes in the sea that are connected to continental ice.

2.The Antarctic ice sheet covers an area of 13.98 million square kilometers, with an average thickness of between 2,000 and 2,500 meters, with the thickest being 4,800 meters and a total volume of 24.5 million cubic kilometers.

3.This huge "ice cap", under the action of its own gravity, slides from the inland plateau to the coastal areas of the central periphery at a speed of 1-30 meters per year, forming thousands of glaciers.

4.At the entrance of the glacier, a large sea ice tongue is formed, which is neither broken nor melted all year round, which is the ** of the sea ice shelf.

5.Huge ice shelves are a unique feature of Antarctica.

6.Around the Antarctic continent, the closer you get to the edge of the continent, the thinner the ice becomes and stretches out into the ocean, where the sea ice floats on the surface of the water, forming a wide ice shelf limb.

7.In other words, ice shelves are the extension of the Antarctic ice sheet into the ocean, and these ice shelves have an average thickness of 475 meters, and the largest ice shelves are the Ross Ice Shelf, the Philcina Ice Shelf, the Ronny Ice Shelf and the Amerian Ice Shelf.

8.With the addition of these ice shelves, the Antarctic continent could increase by 1.5 million square kilometres.

9.Ice shelves can move at a rate of 2,500 meters per year through hail to the ocean, and at their edges, broken ice shelves drift into the ocean, forming huge icebergs.

10.The Antarctic ice shelves cover an area of 1.4 million square kilometers, accounting for 10% of the total area of the Antarctic ice sheet, and the two largest ice shelves, the Ross Ice Shelf and the Filkner Ice Shelf, are both in West Antarctica.

11.Due to its flat surface, the ice shelf is the site of the Antarctic Airport constituency.

12.Antarctic research stations in many countries are built on ice shelves.

13.The Ross Ice Shelf extends 300 to 760 meters seaward each year, so the "floating cities" above it also move towards the ocean every year.

It is covered in snow and ice all year round and is surrounded by the ocean. Since the 80s of the 20th century, it has been found that the ozone over Antarctica has become thinner and thinner, and the stratospheric ozone layer over Antarctica has been rapidly depleted on a large scale every spring.

Antarctica, since its inception, has probably been the coldest place on Earth.

The coldest zones on Earth are in the mountains and the polar regions. Errand service also exists in the northern and southern hemispheres and in different regions. The coldest in Asia is not at the North Pole, nor in the Arctic Circle, but in Oymyakon, at 63° north latitude.

In 1885, it won the title of "cold pole" with a record, and in 1964 it broke the record with a low temperature of -71.

The coldest place in the world is not in the Northern Hemisphere, but in Antarctica, the Southern Hemisphere. Antarctica is covered with snow and ice all year round, the snow thickness is 1700 meters, the solar energy 3 4 is reflected back, and the ground temperature is low. At the beginning of 1967, the Norwegians recorded the temperature at the pole station. <>

The "cold pole" in the northern hemisphere is not at the pole, but in Oymyakon? Because Oi is a place where cold and high pressure have existed for a long time, the terrain is a basin topography, which promotes the accumulation of cold air. The Arctic Circle is the Arctic Ocean, with sea ice on it, and there is still heat transfer from under the ice to the ice, and the temperature is not as low as in Oi.

In North America, the land area is not as large as that of Eurasia, the mountains are north and south, the cold high pressure is not as strong as that of Asia, and it stretches southward, and the cold winter in North America is slightly less than that of Asia. The coldest regions of the Arctic Ocean regulate the climate, similar to Asia, not on the coast of the Arctic Ocean, but in the valleys. The lowest temperature in the Yukon Valley was -63.

In Europe, the coldest is Greenland. The high latitude, the terrain is high, covered by ice sheets, and it is very cold all year round, with temperatures reaching -65 in the Esmit region. Globally, the coldest place is not in the Northern Hemisphere, but in Antarctica.

It is covered with snow and ice all year round, with an average thickness of 1700 meters, 3 4 of the sun's energy is reversed, and the ground temperature is very low. In 1983, the temperature was measured as: , the "cold pole" of the Earth is on the Antarctic continent.

In other parts of the world, for example, a 12-level typhoon has a wind speed of meters, and a wind speed of 10 or more is enough to destroy walls and houses, and cause loss of life and property. In Antarctica, wind speeds can reach meters per second, which is twice as fast as high cars. For this reason, people call Antarctica also known as the "home of the blizzard", or the "wind pole".

Yes, because Antarctica, as the highest latitude continent on the earth, has a surface temperature of more than minus 50 degrees Celsius, making it a place where no one lives and the coldest place on earth.

Yes, Antarctica is the coldest place on Earth at the moment. Humans simply can't survive if they set foot in Antarctica. Because the temperature is so low.

Antarctica has indeed been the coldest zone on Earth since its inception, and very few organisms have survived here.

Yes. Because the coldest area between the peaks of the mountains and the poles, Antarctica is exactly in this area, so it is the coldest zone on Earth.

Because there are many places in Antarctica that are worth exploring, as the last land that humans set foot on, Antarctica still has too many unknown secrets for us. Scientists who have landed in Antarctica have studied large swaths of prehistoric plants that exist beneath the surface of Antarctic glaciers. From this, it is not difficult to deduce that the former Antarctica should have passed a glorious human civilization from here.

In order to explore the development process of human civilization. and Lost Civilizations. Therefore, scientists from all over the world will send people to investigate.

For the study of Antarctica, all countries are working hard. As scientists explore, there is a radioactive furnace under the Antarctic ice sheet. This is a big event that shakes everyone in the scientific community.

Later, scientists discovered a strain known as the ancient virus. However, these viruses cannot be released due to the fact that they are frozen. But when the temperature of the earth's surface rises to a certain point.

Melting glaciers allow this giant virus to spread. At that time, humanity may usher in a catastrophe.

According to eyewitnesses, one day in 2004, a large UFO fleet appeared over Antarctica. Then fly all the way north to South America. But for some unknown reason, after reaching South America, the fleet quickly returned.

According to the report, the American people were once extremely afraid of this fleet, and those mysterious UFOs suddenly appeared in the skies over Mexico. And even flew over their capital. It is also an event that scientists who have traveled to the South Pole have been exploring.

Antarctica is a very cold place. Even boiling water spilled in the air can freeze before it hits the ground. But in the heart of Antarctica, it seems like a miracle that there is an ice-free lake.

This ice-free lake is said to be magical. The water temperature increases as the depth increases. At the bottom of the lake, it can even reach 40 degrees.

Although this has been a long time coming. But the secret of the ice-free lake has not been solved. This has further stimulated our scientists to explore Antarctica.

The mines that the North and South Bureau replied to were amazing. Driven by interests, all countries must have a place there, and they have resources that are not available elsewhere. That's why I went back there to develop.

Because whether it is scientific research or resource occupation, someone needs to go to see Antarctica, and in recent years, Antarctic tourism has also developed, and many people go there every year.

Although the North and South Poles are cold and unsuitable for human habitation, all countries have to send people to taste it, and Britain and the United States want to have their own sovereignty over that land, and they are also preparing for scientific expeditions.

Because the future interests are too great, economic, military, scientific ......And so on, it's just too huge.

The purpose of sending people in the past was to obtain the right to participate and to make preparations for the interests of the special people.

The Antarctic is quite rich in underground resources, and the status of the Arctic and Antarctic is a strategic location in the Arctic Ocean and the Pacific Ocean.

The Antarctic and the North Pole have a lot of resources, and various countries will go there to investigate, and there are risks if you go there and have a bad constitution.

The Arctic and Antarctic resources are abundant and unexploited, and they are borderless resources, and countries will compete for the future, so all countries want to have a place in the first place.

Because there are resources, especially oil and gas, it is better to strike first, and to conduct research on climate and continental history after going there is also good for the future development of the continent.

Because they all want to share a profit, who doesn't want to take advantage of it?

China's Antarctic scientific research projects can be divided into two categories: one is carried out every year, which is called routine observation projects. The other type is only engaged in one or several years, which is called basic capacity support and construction.

From a scientific point of view, the Routine Polar Observation Project is of great value. It's not the data itself that matters, it's the trends and analysis of the data. This type of program covers many basic disciplines such as geophysics, upper-air physics, ocean physics, marine chemistry, microbiology, glaciology, astronomy, paleometeorology, etc.

In this sense alone, it is necessary to organize an annual Antarctic expedition to ensure the continuity of observation data.

Second, politically, the international community is increasingly adopting the principle of "possession and continuous management" for the ownership of unsovereign areas. Organizing an annual Antarctic scientific expedition is also a necessity for the reality of China's polar regions.

AnswerA Antarctica has become a cold pole, due to the high latitudes of the earth, the high level of the earth, the huge thickness of the ice and snow, and the sunlight in the anti-oak reeds, it has become the cold pole of the world.

The coldest region on Earth is the Antarctic region, which, in addition to the severe cold, is also known as the "white desert" and "wind reservoir" on Earth, and the typical animal representing the Arctic is penguins

So the answer is: white desert; Penguins
