Introduction to the Arctic region, climatic characteristics of the Arctic region

The Arctic region is a floating ocean, the Arctic Ocean (60% of the total area), surrounded by permafrost in Asia, Europe and northern North America. The total area is 21 million square kilometers, which is about 1 25 of the total area of the earth. The land area within the Arctic Circle is about 800 square kilometers.

Its land part is divided into eight circumarctic countries: Russia, the United States, Canada, Denmark, Norway, Iceland, Sweden and Finland. The main seas are the Greenland Sea, the Norwegian Sea, the Barents Sea and the White Sea. The famous Arctic magnetic is at 102°54 west longitude and 78°12 north latitude.

The area north of the Arctic Circle is geographically surrounded by three major regions: Asia, Europe and North America, and is nearly semi-closed.

The Arctic refers to the vast area north of 66o33 north latitude (Arctic Circle), also known as the Arctic region. The Arctic region includes the polar Arctic Ocean, marginal land, coastal zones and islands, Arctic tundra, and the outermost taiga belt. If the Arctic Circle is taken as the boundary of the Arctic, the total area of the Arctic region is 10,000 square kilometers, of which the land part accounts for 8 million square kilometers.

Some scientists have also taken the average 10 isotherm in July (5 isotherm in the ocean) as the southern limit of the Arctic region from the perspective of phenology, so that the total area of the Arctic region has expanded to 27 million square kilometers, of which about 12 million square kilometers are land area. If the Arctic were to be delineated by the distribution of plant species and the entire taiga belt would be included in the Arctic range, the Arctic region would cover an area of more than 40 million square kilometers. There is no uniformity in the standards of the Arctic countries as to what is the boundary of the Arctic region, but people are accustomed to using the Arctic Circle as the boundary of the Arctic region from a geographical point of view.

In the North Pole, nature's masterpiece – the Northern Lights – often appears at dusk without clouds. The Northern Lights come in curtains, arcs, and lines, and come in different colors such as red, violet, blue, and cyan. The Northern Lights are light emitted by atoms in the atmosphere when they are excited, just like the atomic spectrum.

The high-energy protons and electrons produced by the combustion of the sun reach the earth after two days, and these particles are attracted by the magnetic field of the north and south poles, and the high-energy electrons will be reflected into the outer atmosphere under the influence of the magnetic field, and collide with oxygen and nitrogen molecules, causing them to decompose into oxygen and nitrogen atoms. When the excited atoms, ions, and molecules return to their ground state, they emit specific wavelengths to form the Northern Lights.

In addition to being notoriously cold and inhospitable, the Arctic is characterized by much of the ocean, or pack ice, rather than freshwater ice, compared to Antarctica. Especially above 82 degrees north latitude, the continuous and year-round sea ice leads to two tourism-related outcomes: the various flora and fauna, including the polar bear at the top of the food chain, cannot survive, and commercial cruise ships are inaccessible due to the ice, so they are hardly a destination for Arctic travel – except for visiting the North Pole in a geographical location.

The Arctic region in winter has two characteristics: the aurora and the polar night. Auroras can be seen above 60 degrees north latitude, especially in Iceland, Norway, Alaska in the United States, and northern Canada.

Polar night refers to a day without sun throughout the day, which gets longer with higher latitude around the winter solstice in the Arctic Circle region.

In the summer Arctic region, there is a polar day phenomenon around the summer solstice - the sun does not set throughout the day, and it also increases with latitude, and can last for more than two months around 80 degrees north latitude. Temperatures in the Arctic are much warmer in the summer than in winter, but they are still cold – especially when the winds are strong, and the weather can change quickly, so you need to keep warm at all times.

Russia, Alaska in the United States, the Canadian Arctic Islands, Greenland in Denmark, Iceland, Norway are all close to the Arctic.

Arctic (Arctic; French: arctique; German: arktis) refers to the northern end of the Earth's axis of rotation, which is the point at 90° north latitude, and the arctic region refers to the area near the North Pole within the 66°34 north latitude of the Arctic Circle.

The Arctic Ocean is surrounded by numerous islands and coastal areas of North America, Europe, and northern Asia. Due to the low temperatures, the Arctic heartland freezes all year round, and it only melts in the summer.

Natural resources

The Arctic Ocean is rich in fish and plankton, which provides abundant food for the millions of seabirds that nest here during the summer**, as well as for seals, whales and other marine animals.

Most of the area around the Arctic Ocean is relatively flat and there are no trees growing. In winter, the ground freezes and the ground is covered with a thick layer of snow. In summer, the snow melts, the topsoil thaws, and plants grow and bloom, providing food for animals such as reindeer and musk oxen.

The Arctic region is located at the northernmost point of the planet and includes the Arctic continent, the Arctic Sea, and the surrounding areas. Among them, Arctic is the core area of the Arctic region, which is known as the "last pure land on earth" due to its unique location and natural environment.

With a total area of about 14 million square kilometers, the Arctic is the largest ice sheet on the earth's surface, covered with ice about 4,000 meters thick. It is estimated that 1 5 percent of the Earth's freshwater resources are stored in the Arctic ice sheet, as well as a large number of mineral resources, energy resources and ecological environments.

The geographical location of the Arctic region is very special and is one of the main controllers of global climate and environmental change. The latitude is about 90°N, which is exactly at the North Pole of the Earth, corresponding to the South Pole.

Because the Arctic region is far from the equator, its climatic characteristics are also obviously different from those of other regions, which is a polar climate, that is, there is no sunshine in winter, the temperature is low throughout the year, and snowfall is frequent. Because the area remains dark for most of the year and the temperatures are very low, most of the life is made up of microorganisms and algae adapted to this extreme environment.

The Arctic region consists mainly of the Arctic continent, the Arctic Sea, and surrounding areas. Among them, the Arctic is the largest part, with a total area of about 14.05 million square kilometers.

The Arctic continent is mainly made up of ice sheets and coastlines, covered with ice up to about 4,000 meters thick. Because the polar environment is extremely severe, fragile and stable, it is one of the last pure lands on the earth, so it is known as the "last pure land on the earth".

The Arctic Sea is also part of the Arctic region, which is the sea area near the central point of the Arctic Ocean, covering an area of about 13.7 million square kilometers. Its waters are covered with ice caps and are home to many polar flora and fauna, including polar bears, seals and seagulls.

The Arctic Sea is also one of the key areas for global environmental and climate change, and changes in sea temperature and sea ice will directly affect the stability of the global climate and the healthy development of marine ecosystems.

In general, the geographical scope of the Arctic region is very vast, including the Arctic continent, the Arctic Sea, and the surrounding areas. Due to its special geographical location and natural environment, the Arctic region has important strategic, scientific and economic value.

At the same time, in the context of global climate and environmental change, the Arctic region has also become an important research and practice field to explore various environmental problems, develop new resources and protect the ecological environment.

Summary. Northern. The North Pole is at 90°N, and everywhere else is to the south of the North Pole, or due south. So, the North Pole is due north of China.

Where is the North Pole in our country?

Hello, I am a teacher of bntom, I have received your question, I will answer it professionally for you within 5 minutes, please wait patiently. ☺️

Mohe, its geographical location is the northernmost part of China, known as "China's Arctic Village". Here, we can see a magical astronomical spectacle - the Northern Lights. Therefore, Mohe Town is also known as the "City That Never Sleeps".

I'm asking for directions, not locations.

Northern. The North Pole is at 90°N, and everywhere else is to the south of the North Pole, or due south. So, the North Pole is due north of China.

It's summer, the North Pole should be in the south! According to the observation of the sunrise and sunset, the south of our country should be the sun that never sets, and it is the North Pole.

The position of the North and South Poles is fixed and does not change with the seasons.

Will you?

You just need to open the world map and you can see the North Pole in China.

As you say, it's the north, so why is the South Pole colder than the North Pole?

The cold has nothing to do with the location.

Is Heilongjiang cold near the North Pole? Is it hot near Antarctica?

It's a matter of latitude, the higher the latitude, the lower the latitude, and the lower the latitude, the higher the temperature.

It's a matter of latitude, the higher the latitude, the lower the temperature, and the lower the latitude, the higher the temperature.

What time is sunrise in Heilongjiang in summer? What time is sunrise in Guangdong?

I follow the sunrise in Heilongjiang in June at 03:46 in Guangzhou at 05:40

This is the relationship between latitude and longitude, if you look at the direction dynamically, the southeast and northwest can be changed at will, if you look at the bearing statically, the North Pole is in the north of China.

Summary. Deep in the Great Khing'an Mountains in the north of Heilongjiang and the northernmost part of China, there is a border town - Mohe Town. It is cold like winter all year round, and even the summer is only about half a month, and the days and nights are short, and the day can reach 19 hours; The temperature peaks at 20 degrees Celsius, and drops to around 10 degrees Celsius at night.

Mohe Township, also known as Mohe Township and Arctic Township, is known as the "Arctic Village of China" and is the only place in China where you can see the Northern Lights.

Hello, I have seen your question and am sorting out the answer, please wait a while

Is it cold in the Arctic or Antarctic?

It's much colder in Antarctica!

So why is Guangdong near Antarctica hotter than Heilongjiang?

China is located in the northern hemisphere, Guangdong is close to the equator, the closer to the equator, the hotter it is.

Now the sun's orbit is southerly, and the southern tip of the earth is the north pole, because it only creates 19 hours of light from the south? Why is there no distinction between the north and the south?

The vernal and autumnal equinoxes are the same line, the only result of the polarization of the summer and winter solstices. The Tropic of Cancer of the Earth.

Guangdong near the Tropic of Cancer or the Tropic of Cancer?

Guangdong near the Tropic of Cancer.

1.Range. Arctic.

It includes the area south of the Arctic Circle, including the Arctic Ocean and the northern part of Arctic Continent, Asia, and Europe, and is dominated by the ocean.

Antarctic. It includes the Antarctic continent and its coastal islands and continental margin ice, as well as parts of the Atlantic, Pacific, and Indian Oceans, which are dominated by land.

Climatic characteristics: The common climatic characteristics of the polar regions are severe cold, and the common natural landscape is the ice and snow world, with a large amount of ice floes. Characteristics of the Antarctic region: extremely cold, strong winds, scarce precipitation, known as the "world's cold pole" and "white desert".
