Cold air activity is still frequent during March 9. Why are there so many extreme weather this year?

Presumably, many friends have already felt this year, that is, the cold air is very rampant this year, and there has been a strong cooling situation all over the country. So now that we have entered the third nine-year plan period, will there be other extreme weather? Share it with you here. First of all, according to the data given by the News and Meteorological Bureau, the probability of extreme weather has been greatly reduced, mainly because there are many and stable cold air now, occupying most parts of North China and Northeast China. Under such circumstances, although the temperature is relatively low, because Kia is relatively stable, there will be no large-scale extreme weather conditions. I hope everyone can rest assured. Then share with you why there are so many extreme weather this year, and everyone can like it and pay attention to it.

First, the global greenhouse effect.

Perhaps many people don't understand why the temperature rises gradually and the global greenhouse effect will lead to the temperature drop. In fact, this is mainly because with the global temperature rising, the temperature in the polar regions is also rising gradually. At this time, the temperature and pressure between them and our mid-latitude area will contract, resulting in airflow chaos between the two areas. In this scenario, the polar cold air flow will go south and then hit the mid-latitude area. In this case, because of the convergence of cold and warm air currents, many extreme weather will be caused.

Second, where is the extreme weather mainly concentrated this time?

First of all, we should know that although the temperature in our country is not very high now, many areas have warmed up. But what everyone needs to be alert to here is the rush phenomenon, which does not mean that the door will not be closed, because according to the data of supercomputers, a strong cold air mass has been re-formed in northern China and will enter China in the near future. Followed by a large-scale cooling.

Third, will the temperature rise after March 9?

According to the data, although there will be a large-scale cooling this time, the cooling will not be very strong, and then the temperature will rise again, because the current cold air mass is obviously insufficient, and it will only cool down for a short time, which will basically lead to this winter. Of course, because there will be a cold spring in previous years, there may be another wave of cooling in spring. Generally speaking, this year's winter is relatively cold in the early stage, the temperature is relatively stable in the later stage, and the temperature will rise in the later stage, but the central region is basically alternating between cold and warm.
