Since the earth is tilted, the angle of sunlight hitting the poles is large, which makes the unit area receive less sunlight resulting in no heat, so it is cold.
The second is the polar night problem.
It is also the above reasons that cause the polar night phenomenon in the North and South Poles, that is, there is no sun at all for the whole day. It's winter.
White glaciers are also a factor.

Anonymous users2024-02-051. 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.

Anonymous users2024-02-04(1) The Arctic region is well known as the 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. Theoretically, the temperature in the Antarctic region is of course colder than in the Arctic!
The main factors that affect the wind on Earth are: horizontal pressure gradient, geostrophic deflection force, and frictional force. Among them, the horizontal pressure gradient is the key to the formation of the wind, which affects the strength of the wind, the geostrophic deflection force affects the direction of the wind, and the frictional force weakens the speed of the wind. >>>More
The main reason for cold hands and feet is that the function of the autonomic nervous system is not smooth, and the blood vessels are thinned. In addition, the toes, knees, shoulders, fingers, etc. are all joints that exercise more, so there is less fat, heat is easy to lose, and there are fewer blood vessels, so it is easier to feel cold. >>>More
The reasons for cold hands and feet in winter are:
1. Kidney Yang deficiency. The most common cause of cold hands and feet is kidney yang deficiency, which can be easily felt by people with kidney yang deficiency even at normal temperatures. >>>More
Many people will feel comfortable and happy when they see how sunny it is, but on the contrary, they will feel depressed, irritable and sad! Presumably this has something to do with everyone's thinking, personality and way of thinking! When the weather is good, the sky is mostly bright, and vice versa, the sky is dark, and people have a lot of similar feelings about color!
Why do some people love cleanliness and others are sloppy? Sloppy people themselves don't have a sense of cleanliness or are they lazy and don't want to clean up? >>>More
