December 11, 14:00 pm, from the point of view of the hour temperature map, today although the temperature in many parts of northeast China has dropped significantly, the northeast plain has returned to sub-zero, but the previous warm tide impact is still lingering on the northeast plain - 14:00 pm, the temperature in many places in the southeast of the northeast plain is still above 0 degrees, especially in Liaoning, at 14:00 pm, the temperature of many stations is more than 5 degrees, such as Suizhong, such as suizhong, the temperature of individual stations is more than 10 degrees, once very warm, in mid-December, Such temperatures are indeed quite rare.
In fact, the previous warm wave was also a historic strong warming process for the northeast, for example, on December 9, the maximum temperature of Shuangyashan In Heilongjiang was as high as 8.7 degrees, breaking the local record for the highest temperature in December (the original record of 7.8 degrees, appeared on December 2, 1958), and the recent temperature in many other places also entered the top ten of the highest temperature in December. The northeast, which has been warmer than a lot, has become more warm in recent days.
In this temperature mode, recently, the precipitation in the northeast has become a rain that is rare in winter - for example, on the evening of December 9, there was significant precipitation in Shenyang, but monitoring data shows that the precipitation in Shenyang is accompanied by a temperature close to about 5 degrees, which is undoubtedly rain.
In addition to Shenyang, in fact, in the two days of the three eastern provinces in the serious warm temperature, there are few rain in December, many netizens feedback: Heilongjiang, Jilin many places have also recently rained, many netizens said that this time the rain is really not seen!
So what's going on? Is it a sign of a climate anomaly? Or is this year's cold winter really going to warm up? Judging from the temperature distance monitoring data of the National Climate Center of the China Meteorological Administration, since December, in addition to the low temperature in the western and southern coastal parts of China, the temperature in most other areas is high, especially in northern Xinjiang, north China, northeast China and other places are generally seriously high, especially in the eastern and northeast of Inner Mongolia, many places are more than 6 degrees high, which is seriously high, which corresponds to the recent rain in the northeast.
The main reason for this change is the recent development of too strong warm ridges in the westerly wind belt in East Asia, which has led to a strong warming of warm air. In fact, whether it is the previous continuous cold wave or the current great warming, it means that there are strong signs of economic activity in the northern hemisphere this year - that is, the westerly wind belt often oscillates violently, and the cold and warm air often moves south or in huge amounts of north, in this case, it is more likely to appear violent fluctuations in temperature, but will this be a sign of warm winter? In fact, it is not necessarily, under the change of cold and warm air, the warm winter is actually not certain.
