North and south poles, with extreme high temperature weather! Scientist: This is absolutely unusual
Many meteorologists have recently observed extreme high temperature weather in the North and South Polar areas, and the temperature in some areas exceeds the average level of 30 to 40 degrees Celsius in the same period of previous years.
Under normal circumstances, the temperature of the Antarctica will gradually decline with the southern hemisphere from summer to autumn. However, multiple inspection stations in Antarctica recorded high temperatures on the 18th of this month. According to Agence France -Presse, the French Meteorological Agency Meteorologicalist Etien Carpikian said in social media that the temperature of the Kangcodia Antarctic Survey Station co -established in France and Italy was measured at minus 11.5 degrees Celsius on the 18th, creating the highest history in history, and the highest history was the highest in history. Record. This number is about 40 degrees Celsius higher than the same period of previous years.
Ruonaton Willer, a polar meteorist at the University of Gleo Nuo Bill, in France, said in social media that the temperature measured by the Convoke Survey Station is 1.5 degrees Celsius higher than the highest temperature record in the past. Essence
Matthew Lazala, a meteorologist at Wisconsin University, observed the 18-day temperature of the Southern and Total Ice Dome C-II region, and the average temperature was minus 43 degrees Celsius in the same period of previous years. “This temperature should appear in January instead of March. It is summer in January. It’s exaggerated.”
The Associated Press quoted the U.S. National Ice and Snow Data Research Center scientist Walter Maye, reported that the temperature in part of the Arctic in mid -March was about 30 degrees Celsius higher than the same period of the previous year. Some areas of temperatures even approached or reached freezing points, which was extremely rare.
Miye said that the season of the north and south poles is the opposite season, but at the same time, extreme high temperature weather appears, “absolutely unusual” and “quite amazing.”
Lazala and Miye believe that the high temperature weather in Antarctica may only happen by accident. However, once a similar situation occurs or repeatedly, it may be worrying.
Researchers at the University of Mine at the United States said that based on the weather model established by the National Oceanic and atmospheric Administration, compared with the same period of the same period from 1979 to 2000, the temperature as a whole on the 18th of this month was about 4.8 degrees Celsius. It is 3.3 degrees Celsius, while the global overall is 0.6 degrees Celsius.
Globally, the average temperature from 1979 to 2000 was about 0.3 degrees Celsius higher than the average level of the 20th century.
According to data from the National Ice and Snow Data Research Center, the area of Antarctica sea ice decreased in late February to approximately 1.9 million square kilometers. It was the first time since the relevant records in 1979 fell below the 2 million square kilometers. In addition, the climate warming speed of the Arctic region is two to three times the other areas of the earth. The warm air over the Atlantic Ocean is moving north along the coast of Greenland.
