Antarctic temperature

"Antarctic temperature refers to the temperature on the Antarctic continent. The extreme maximum temperature is 20.75 degrees Celsius above zero, and the extreme minimum temperature is MINUS 94.2 degrees Celsius. "

The Antarctic continent is the coldest region in the world because of its high altitude, thin air and solar radiation reflected from the ice and snow surface, and its average temperature is 20 degrees Celsius lower than that of the North Pole. The average annual temperature in the Antarctic continent is MINUS 25 degrees Celsius.

The average annual temperature in Antarctic coastal areas is about-17 to -20 degrees Celsius. The average annual temperature in inland areas is MINUS 40 to MINUS 50 degrees Celsius; The southeast plateau is the coldest, with the annual average temperature as low as -53 degrees Celsius. The lowest temperature observed on the earth is -93.2 degrees Celsius, which was recorded in August of 20 10 in the United States. At this low temperature, ordinary steel will become as fragile as glass. If you throw a glass of water into the air, it will become ice crystals.

First of all, the cold of Antarctica is related to its high latitude location, which leads to no sunshine in the long polar nights of the year. It is also 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.
