Why is the South Pole colder than the North Pole and why is the South Pole colder than the North Pol

The Antarctic is colder and has more glaciers than the Arctic, because the Antarctic region is a continent with a weak ability to store heat, and the heat gained in the summer is quickly radiated, resulting in an average annual temperature of -56 in Antarctica. In the ocean around the Antarctic continent, a large amount of ice floats, forming huge icebergs.

In contrast, the Arctic region has a small land area and is mostly the Arctic Ocean. Due to the large heat capacity of seawater, it can absorb more heat, and the heat is dissipated more slowly, so the average annual temperature there is higher than that of Antarctica, around 8. As a result, there are fewer glaciers in the Arctic than in the Antarctic, and most of them accumulate on Greenland.

According to the survey, the average thickness of the ice in Antarctica is 1,700 meters, and the thickest point can reach 4,000 meters, and the total volume of glaciers is about 28 million cubic kilometers. The ice in the Arctic is about 2.4 meters thick, and the total volume of glaciers is only one-tenth that of Antarctica.

The Antarctic is the continent and ice sheet, and the North Pole is the sea surface. The specific heat of water is very large, and it has a good buffering effect on heat.

The thermal properties of the continents and the oceans are related, and the altitude is related.

1. The Antarctic has a high altitude, 2. At the same time, the North Pole is dominated by ice and reflects more sunlight than the North Pole. 3. The North Pole is closer to the continent than the South Pole.

The ice at the South Pole is thick and large, reflecting solar radiation into outer space, receiving less solar radiation and certainly colder! The Arctic has less land and less ice.

Wrong. The north and south poles are both 90 degrees latitude.

1) The Arctic region is fed by the famous North Atlantic Current. It also carries a large amount of warm and moist air into the Arctic, causing the sea area where the North Atlantic current passes not to freeze even in winter. For example, the famous Murmansk military port in Russia is the best example.

The Murmansk military port is located in the Arctic Circle, but due to the warm current of the North Atlantic, it is the only perennial ice-free port in the waters near the Arctic in Russia!

2) There is no land in the Arctic Circle, most of it is the Arctic Ocean. Theoretically, the temperature in the Arctic should also be a little higher than in the Antarctic.

3) The Antarctic is surrounded by the famous westerly circulation. The water temperature in the sea area through which the westerly circulation passes is very low and largely unchanged. The westerly circulation carries a dry and cold current.

The westerly circulation acts as a strong barrier to Antarctica. It deprives Antarctica of the possibility of exchanging heat with the outside world. And it is precisely because of the westerly circulation that there is no warm current that can flow into the South Pole!

4) Unlike the Arctic, the Antarctic is mainly made up of land. In the North Pole, the sun never rises high in the sky, and even in midsummer, it does not rise at an angle of more than degrees. Annual precipitation in the Arctic is generally 100-250 mm, and in Greenland it can reach 500 mm, and precipitation is concentrated on offshore land, mainly in the form of summer rain.

5) It may be because the earth rotates and revolves obliquely, and because the earth is an irregular sphere, so when the sun hits the earth, the southern hemisphere gets less light and heat than the northern hemisphere, so the southern hemisphere is colder than the northern hemisphere.

6) Antarctica is mainly composed of land, and the specific heat of land is smaller than that of the ocean.

The altitude of the South Pole is much higher than that of the North Pole.

There is land in Antarctica, and the specific heat of sand and soil is smaller than that of water, so the temperature difference is large, and it is cold.

The Arctic underlying is the Arctic Ocean, and the Antarctic underlying is the continent of Antarctica.

The specific heat capacity of the continent is relatively small, so it is colder.

1. The Antarctic is the land, while the Arctic is the ocean, the land is small in terms of specific heat, and it heats up and cools down quickly, so the Antarctic is colder than the Arctic; 2. The altitude of Antarctica is relatively high, with an average altitude of more than 2,000 meters, and the temperature drops every 1,000 meters of increase. 3. The South Pole is the farthest place from the Sun in winter, while the North Pole is the closest place to the Sun in winter.

One is that Antarctica is land, and the North Pole is the ocean, the Arctic Ocean. Because the land has less specific heat, it warms up and cools down faster, so the South Pole in winter is colder than the North Pole in winter. This is the most important reason for the temperature difference between the two stages.

Second, Antarctica has a high latitude and a small solar altitude angle, so the solar radiation passes through the atmosphere for a long time, and it is weakened by the atmosphere more, and even less reaches the ground; The solar altitude angle is small, and the same amount of solar radiation is dispersed in a large area, so the solar radiation per unit area is less. So the average temperature is lower. In addition, the South Pole is the farthest point of the Earth from the Sun during the winter months, while the North Pole is the closest place to the Sun during the winter months.

Third, the center of Antarctica is a polar high pressure area, and the airflow flows from the center to the surrounding areas, blocking warm air from low latitudes from entering the Antarctic continent; In addition, there is also the Antarctic Circulation on the periphery of Antarctica, which is a cold current and has a cooling and dehumidifying effect. Therefore, the temperature in the Antarctic continent is low. Fourth, Antarctica is a plateau continent with an average altitude of 2,350 meters, the highest average altitude in the world; Nearly two-thirds of the Arctic is ocean, and the average elevation is only about the same as sea level.

As the saying goes, "it's not cold in high places", so the temperature in Antarctica is relatively low.

Answer: Surface nature The Antarctic region is made up of the Antarctic continent and nearby islands, and the interior of the continent is less affected by the ocean. Most of Antarctica is covered by continental ice sheets, which are thick and unmelting all year round.

The Arctic region is a land area surrounding the sea, and the winter ice cover is smaller than that of the Antarctic region. Ice and snow in the Arctic melt during the summer, resulting in a smaller summer ice area.

Ocean Currents The Arctic is warmer than the South Pole due to the warm North Atlantic Current.

Wind The polar region is located at high latitudes and is controlled by polar high pressure all year round. Antarctica is high, with strong polar easterly winds blowing from the center of the continent to its edges. Antarctica is known as the world's most windy pole.

The Arctic is a low-lying ocean with relatively weak winds from the polar easterly.

Height of the Sun The Earth is an irregular spheroid with slightly flattened poles and a slightly bulging equator, and its North Pole radius is slightly larger than the South Pole radius. As a result, the average solar altitude in the Antarctic region is smaller than that of the North Pole, resulting in less solar radiation per unit area and lower temperatures.

Number of polar night days When the Earth is at aphelion, the Antarctic region is in a polar night state. At this time, the Earth's revolution is slower. This results in more polar nights in the Antarctic Circle than in the Arctic Circle.

In other words, the Antarctic region takes a little longer to release heat into space than the Arctic region.

Altitude The Antarctic continent is the highest continent in the world. The Antarctic region is a bit higher above sea level than the North Pole. There is a strong relationship between temperature and altitude, with an average increase of 1 km in temperature decreasing by 6 km. As the saying goes, it's too cold to be in high places.
