Recently, many parts of the continent's central and eastern parts have experienced drastic changes in weather, first unusually hot, followed by a sharp cooling. For example, in Chongqing in the Sichuan Basin, the temperature on March 19 was as high as 32.4 degrees Celsius (referred to as degrees, the same below), but the maximum temperature on March 21 was only about 15 degrees, directly dropping more than 15 degrees, and at the same time, accompanied by miserable wind and cold rain, many people have put away short-sleeved shorts, which makes many netizens sigh: This year's weather is indeed too abnormal!
However, the abnormal climate is also spreading in other parts of the planet, even the northernmost and southernmost poles of the earth are no exception - on March 18, Antarctica ushered in a rare large-scale "heat wave", france and Italy jointly opened Concordia, located in the Antarctic plateau ice dome C area, -12.2 degrees Celsius was recorded on March 18, setting a new record for the highest temperature of the year since the station was built in 2005, such as the -13.7 degrees Celsius record set on December 17, 2016.
Orient Station is an Antarctic scientific research station located in princess Elizabeth, inland on the Antarctic continent, near the Southern Magnetic Pole. Founded by the Soviet Union in 1957 and located in the interior of the Antarctic Plateau, the station is famous for recording the lowest natural temperature on Earth - 89.2 degrees, but on March 19, the site recorded -17.7 degrees, refreshing the march maximum temperature record, nearly 15 degrees higher than the original record!
Whether it is Dongfang Station or Kanghong Station, the previous monitoring data shows that the maximum temperature here is still about -50 degrees, the average temperature is about -50 to -60 degrees, and the temperature from March 18 to March 19, the average temperature has risen by more than 45 degrees in a week, and the high temperature has risen by nearly 47 degrees! Although this is not the "high temperature above 35 degrees" as we generally understand it, if there is such a high temperature in the North and South Poles, it is really a mess of climate, but even so, the violent heating of 40 degrees is still quite extreme. It's early autumn in the southern hemisphere, and you can imagine a sudden rise from 10 degrees to 50 degrees in the northeast in September. At present, the temperature of Dongfang Station and Kanghong Station has begun to drop, but it is still significantly higher.
At the same time, the analysis data shows that on March 18, the temperature of the current East Antarctic Plateau in Antarctica reached 30 to 35 degrees from the level of the positive distance, which is a serious large-scale high temperature, occupying more than a quarter of the Antarctic continent, which is one of the most extreme weather events this year, but because it is almost unmanned, it occurs in a "silent" way.
At the same time that the Antarctic encountered abnormal "high temperatures", the Arctic also suffered abnormal warming at the same time - on March 17, the analysis data showed that there was a large range of strong warming over the Arctic Ocean, and the warmer area reached a maximum of more than 30 degrees above the positive level, which was also a rather crazy violent warming.
Then some netizens have to ask: how can the north and south poles suddenly heat up violently at the same time, is the earth inflamed? From the perspective of weather conditions, from March 17 to 18, the north and south hemisphere westerly wind belts simultaneously appeared violent oscillations, such as the Antarctic, the East Antarctic plateau appeared a strong warm blocking high pressure, resulting in a large number of heating masses into the Arctic Ocean and antarctic continent, so that some areas warmed up 30-40 degrees in two days, breaking the March record. Although the heating is extreme, it is still limited to the weather level, the time is relatively short, the impact is only a moment, and the follow-up impact is still worth observing.
Of course, the current temperature is falling, and not the entire North and South Poles have abnormal warming, but this situation is still worth vigilance, many climate researchers in France and the United States said that this situation is "unprecedented", which is considered to be part of climate change, and the performance of climate change in addition to the average temperature rise is also reflected in the increase in such extreme events. In the short term, the energy of this violent oscillation may continue to be transmitted within the northern and southern hemispheres, and extreme weather may also occur in other regions.
