Extreme cold wave returns? Zheng Mingdian warns: Stratosphere warming is "obviously early"

Zheng Mingdian, the former director of the Central Meteorological Bureau, published an article yesterday to share the high-altitude observation chart of the Arctic. He said that the temperature over the Arctic rose from -69 degrees to -54 degrees in a short period of time, and what is special is that the "stratosphere warming" obviously occurred earlier! The post also triggered discussions among netizens. Many netizens speculated that "the refrigerator will not close", "the dominant cold wave will return to Taiwan again", "negative Arctic shock may occur", etc.

Zheng Mingdian posted on Facebook to share the temperature record at an altitude of about 23 kilometers above the North Pole. He said that the temperature record about 4 days ago was about -69 degrees, but the subsequent temperature quickly rose to the current level of about -54 degrees, rising by nearly 15 degrees Celsius in a short period of time!

Zheng Mingdian said that stratospheric warming has been defined by different scholars. Conceptually, they all describe the phenomenon of rapid warming of the stratosphere over the polar regions in a short period of time (a few days to 1 to 2 weeks).

Regarding this increase in temperature, Zheng Mingdian bluntly stated that the extreme value of the increase in temperature has not yet broken the record, but it has clearly fallen within the most extreme 10% range. He also emphasized that what is truly special about the record is not the magnitude of the increase in temperature, but the fact that it occurred significantly earlier in the season!

Under the post, netizens also expressed that "the cold air is moving south", "the refrigerator will not close", "it seems that polar shocks are inevitable", "stratosphere warming will occur earlier, and the most direct impact will be to significantly increase the chance of the northern hemisphere encountering an "extreme cold wave" early this winter", "cold air will not "It will disappear and move to mid- and low-latitudes, and the negative Arctic Oscillation in 2016 may occur." "Some European and American meteorologists are also paying special attention to this issue. They speculate that this unusually early stratospheric warming may cause some areas in the mid-latitudes to be directly hit by strong cold air from the Arctic surface."
