Antarctic temperature
"Antarctic temperature refers to the temperature on the Antarctic continent. The extreme maximum temperature reaches 20.75 degrees Celsius above zero, and the extreme minimum temperature is minus 94.2 degrees Celsius."
Due to the high altitude of Antarctica, the air Thinness, coupled with the reflection of solar radiation by the ice and snow surface, makes the Antarctic continent the coldest region in the world, with an average temperature 20 degrees Celsius lower than the Arctic. The average annual temperature on the Antarctic continent is minus 25 degrees Celsius.
The annual average temperature in the coastal areas of Antarctica is about minus 17 to minus 20 degrees Celsius; while the average annual temperature in the inland areas is minus 40 to minus 50 degrees Celsius; the East Antarctic Plateau is the coldest, with the average annual temperature as low as minus 53 degrees Celsius. The lowest temperature observed on the earth is minus 93.2 degrees Celsius, which was recorded in the United States in August 2010. At such low temperatures, ordinary steel will become as brittle as glass; if a glass of water is thrown into the air, it will fall What came turned out to be a piece of ice crystal.
The coldness of Antarctica is first of all related to its high-latitude geographical location. Due to its high-latitude geographical location, there is no sunlight during the long polar night of the year. At the same time, it is related to the incident angle of sunlight. The higher the latitude, the smaller the incident angle of sunlight, and the less solar heat energy absorbed per unit area.
