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. The temperature in most parts of northern China continues to bottom out.
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!
More than 20 provinces are as cold as "drill refrigerators"!
According to Wang Weiyue, a meteorological analyst at China Weather Network, on December 20, the highest 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 timesMore than 20 provinces are as cold as "drill refrigerators"!
On December 23, the impact of cold air on our country 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 soft freezer area 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 and entered the refrigerator.
Why is this winter so cold?
According to the National Climate Center's previous **.
Most of our country this winter.
Temperatures are close to normal or on the high side.
Many netizens are discussing:
"Say goodbye to the warm winter."
"Will it be a warm winter this year?" ......
According to the National Climate Center, talking about a certain year or month is warmer, not determined by a single weather eventRather, it compares whether the average temperature over the entire period is significantly higher or lower than that of the historical period
Statistical analysis based on historical dataUnder the background of El Niño, the winter temperature in China is generally warm, 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 disturbance of the Arctic vortex and the westerly wind belt in the middle and high latitudes. Although the warming rate is higher than the global average, the intensity of extreme cold waves has not weakened, and the influence range of strong cold air or cold waves has increased.
The data shows that in early December this year, China was significantly warmer, 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 in the country was -13, 0. higher than the same period of the year9. The temperature in most parts of the country is 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, the north of Heilongjiang, most of the country, and the southern part of Qinghai The temperature is lower than that of the same period in normal years, and the temperature in most parts of China is close to normal, but the cold and warm fluctuations are obvious, or the temperature "roller coaster" will be experienced again.
