It's not as cold as February 9 this year. What caused it to be so cold on February 9?

On the past 19 and 29, from the end of 65438+February in 2020 to New Year's Day in 2002/kloc-0, China suffered two consecutive super cold waves, and the temperature dropped continuously, setting a record for the lowest temperature in winter. Moreover, this is not only the coldest situation this year, but also the lowest since meteorological records began in 2 1 century. Some experts say that March 9 this year may not be as cold as February 9. Why? Let's talk about it today

As the saying goes, it is hot at three volts and cold at three or nine. Originally, the lowest temperature in three or nine days every year would make people feel the greatest chill, but this year's situation is quite special. In these two days, I can obviously feel the temperature rising, which is warmer than the 29th period. 654381During the period from October 5 to 8, and in the last few days of February 9, a new round of cold wave hit many areas in China, which caused the temperature to drop and then dropped to freezing point. This is one of the coldest 29 in history.

According to meteorological data, during the 29th, Datong, Shanxi and Qingdao, Shandong recorded the lowest temperatures at their respective observation stations. Temperature observation stations were established in Qingdao, Shandong 196 1 and Datong, Shanxi 1955. In other words, the temperature in February and September this year was the coldest in 60 years. In addition, in Jinan, Tianjin and other areas, the temperature is the third lowest and the second lowest on the meteorological record. Therefore, it is obvious that February 9 this year is too cold.

Today, we don't analyze this problem from the perspective of the formation and development of the cold current. We think it belongs to a social phenomenon. Everything basically has peaks and valleys, and it will not be stable all the time. The weather temperature is the same, high and low, and it must be cold when it is warm. Generally, there will be a wave of rebound after extremely low weather. As it is now, that's it.

During February 9, the temperature has reached the lowest level in history. Under normal circumstances, after the cold wave has gone, the temperature will definitely rise. And now, this is just a powerful proof of this fact. Although there must be a cold wave after the cold wave, there must be a certain interval between the cold wave and the cold wave. It is at this time this year that the temperature rises and the weather improves. Generally speaking, although the temperature in March and September this year is not as cold as that in February and September, it is still lower in most areas than last year, and there will be a cold wave coming. According to the current meteorological observation, there will still be cold air moving from north to south in the next 13~ 17 days, which may affect most parts of China, especially the east. Everyone should also do a good job of cold protection and warmth. The old saying that it is cold on March 9 is very reasonable, and we can't abandon this concept just because the temperature rises in these two days.
