Why is Antarctica called the wind reservoir and the cold pole?

1. Antarctica has a high latitude, a small solar altitude angle, a long atmospheric distance through which the same amount of solar radiation passes, a strong weakening effect by the atmosphere, less solar radiation reaching the ground, and a relatively large area of solar radiation reaching the ground, less solar radiation per unit area, and very low temperature.

2. Antarctica is a land with small specific heat and large temperature difference, colder winters and lower temperatures.

3. Antarctica has a high altitude and even lower temperatures.

4. Antarctica is covered with ice and snow, and the silvery-white ice and snow have extremely strong reflectivity, and most of the solar radiation projected on it is reflected back into the universe, making the temperature even lower.

Wind bank. Generally speaking, tropical storms (typhoons) can reach Category 12 only in the ocean, but storms above Category 12 are common in Antarctica. The Antarctic continent is the most stormy and windy continent, and high winds of more than 100 kilometers per hour are common in Antarctica.

The winds are strongest in the coastal zone of the Antarctic continent, with an average wind speed of 17 18 metres per second, while the coastal zone of the East Antarctic continent is the strongest, with winds reaching 40 50 metres per second. At the Dearville station in France, a gale of 100 meters per second was measured, which is three times the wind speed of a Category 12 typhoon, and its destructive power is nearly 10 times that of a Category 12 typhoon. This is by far the largest wind ever recorded in the world.

For this reason, Antarctica is also known as the "wind pole".

Antarctic wind can kill! In addition to the bitter cold, the squall is another formidable enemy that scientific expeditions encounter in Antarctica. Strong winds can quickly take away the heat of the human body, causing frostbite and even freezing to death.

Polar night storms, whose speed sometimes exceeds 4 0 meters per second, are much more severe than 1 2 typhoons. At this time, if someone is outside, there will be a danger to their lives. It is hard to forget that on the afternoon of 1 9 6 0 1 0 1 0, Dr. Fukushima, who was conducting a scientific expedition at Showa Station in Japan, walked out of the base canteen to feed the dogs, and suddenly encountered a snowstorm of 3 5 meters per second, and never returned.

Until February 9, 1 9 6 7, his well-preserved body was actually in the 4 th distance from the station areaAppears at 2 km!

1. The latitude of Nandou Antarctica is high, the solar altitude angle is small, the same amount of solar radiation passes through the atmosphere is long, the atmospheric weakening effect is strong, the solar radiation reaching the ground is less, and the solar radiation dispersion area reaching the ground is relatively large, the solar radiation obtained per unit area is less, and the temperature is very low.

2. Antarctica is a land with small specific heat and large temperature difference, colder winters and lower temperatures.

3. Antarctica has a high altitude and even lower temperatures.

4. Antarctica is covered with ice and snow, and the silvery-white ice and snow have a strong reflectivity, and most of the solar radiation projected on it is reflected back to the cosmic space, making the temperature even lower.
