It's cold all year round.

The climate is extremely cold, covered with ice and snow all year round, and it belongs to the cold zone ice field climate, and is known as the world wind bank, cold pole and dry pole. The average annual temperature in the whole continent is MINUS 25℃, the average temperature in the inland plateau is about MINUS 56℃, and the extreme minimum temperature reaches MINUS 89.2℃, making it the coldest land in the world. The average wind speed of the whole continent is17.8m/s, and the coastal surface wind speed often reaches 45m/s, and the maximum wind speed can reach more than 75m/s, making it the strongest and windiest area in the world. The precipitation in most areas is less than 250 mm, and it can reach about 500 mm only in the marginal areas of the mainland. The average annual precipitation in the whole mainland is 55 mm, and the annual precipitation in the mainland is only about 30 mm. There is almost no precipitation near the pole, and the air is very dry. Polar high pressure has been around for many years, and there is little water vapor. However, because the temperature is below zero all the year round, the accumulation of ice and snow does not melt. It is called "White Desert".

By observing the thickness of frozen layer there every year, we can know the pollution of the earth's atmosphere. Because the strong westerly winds around the Antarctic continent block the opportunity for the ozone layer to communicate with the outside world, and because the early sunlight promotes the combination of chlorofluorocarbons and ozone molecules in the air and decomposes the ozone layer, the ozone layer in this area is particularly thin at the turn of winter and spring, and has strong ultraviolet rays. Since1980s, this situation has become more serious after a large number of chlorofluorocarbons have been discharged from industries all over the world. However, some scholars have different views. Since the west wind is the barrier, industrialized countries are mainly in the northern hemisphere, why is HCFCs most in the Antarctic? They are considered as masterpieces of the weakening of the earth's magnetic field and the solar wind.
