The effects of the strongest cold spell since this winter have just ended
This week, a new wave of cold air continued
Be affected by it
Temperatures in most parts of the northern part of the continent continue to bottom
Constantly refresh the new lows in the second half of the year
Yantai and Weihai areas were hit by cold blizzards
The cold snow is raging, like an Arctic expedition!
According to Wang Weiyue, a meteorological analyst at China Weather Network, on December 20, the maximum temperature in Northeast China and North China hit a new low in half a year. On the 20th and 21st, the temperature in many places in the south also dropped to the lowest point in recent times, and more than 20 provinces were as cold as "drilling refrigerators".
On December 23, the influence of cold air on the continent tends to end. The northern part of Heilongjiang and the northeastern part of Inner Mongolia are still in the frozen layer, and the cold is not reduced. The area of the soft cryogenic layer has been greatly reduced, and the maximum temperature in most parts of Jiangsu, Anhui, and Shandong, as well as the southern part of Hebei and central Shaanxi, has returned to above 0 °C and entered the refrigerator.
According to the previous forecast of the National Climate Center
This winter in most parts of the continent
Temperatures are close to normal or on the high side
Many netizens are discussing:
"What about the warm winter?"
"Will it be a warm winter this year......
According to the National Climate Center, when talking about a certain year or month being warmer, it is not determined by a single weather event, but by comparing whether the average temperature of the whole period of time is significantly higher or lower than that of the same period in history.
According to the statistical analysis of historical data, the winter temperature of the continent is generally warm under the background of El Niño, but the periodic cold air activities are more frequent, that is, the fluctuations of cold and warm are more obvious.
Since winter, the average temperature of the country has undergone a "roller coaster" change
The intensity of the cold air process is not only affected by El Niño, but also has a lot to do with the fragmentation of the Arctic vortex and the disturbance of the mid- and high-latitude westerly wind belt. Although the warming rate is higher than the global average, the intensity of extreme cold waves has not weakened, and the impact range of strong cold air or cold waves has increased.
The data shows that the mainland was significantly warmer in early December this year, and the temperature dropped significantly in the middle of the month. Since December (as of Monday), most parts of the north have received significantly more precipitation. During this period, the average temperature of the country was -1.3 °C, 0.9 °C higher than that of the same period in normal years, and the temperature in most parts of the country was mainly high.
After the country experienced a sustained warm period in the early stage, it was followed by a sharp cooling. Since December 14, affected by a wide range of cold waves, the temperature in most parts of the country has plummeted, and the maximum daily cooling range of some national meteorological stations has exceeded the historical extreme.
This winter has just begun, and it is expected that the intensity of the East Asian winter monsoon will be generally weak in the second winter (January-February 2024), except for the northeast of Inner Mongolia, northern Heilongjiang, most of Tibet, southern Qinghai and other places where the temperature is lower than that of the same period of the year, the temperature in most parts of the mainland is close to normal, but the cold and warm fluctuations are obvious, or the temperature "roller coaster" will be experienced again.
