China's first large-scale rain and snow went online. Why is it so cold this year?

Probably this year is a special year, because at the beginning of 2020, COVID-19 epidemic just broke out in our country, and the whole country is contributing to the COVID-19 epidemic, and in order to ensure people's safety, people all over the country basically stay at home for about 4 to 5 months. So this time is not very sensitive to an environmental climate change in China. Then, probably in the recent winter of 2020, there was a large area of rain and snow for the first time in China. Why is it so cold this year? There are probably the following reasons.

1. The temperature is too high this summer. First of all, 1 is probably a summer this year, and the temperature is really too high, because in many places in China, its highest temperature has soared to the highest temperature in history, and Xiamen, Hangzhou and other regions have reached about 4 12 degrees, which is the highest in history. It is conceivable that this summer is the hottest in China's history. The highest temperature in Death Valley in the United States is 54.6℃, so the extreme weather in winter brought by a hot summer is getting more and more serious.

Second, El Nino and Latin American Nina are getting worse and worse. At the same time, these phenomena are very serious in 2020 this year, and the global temperature has generally risen to a higher level than the same period last year, so in winter, all kinds of cold climates are getting more and more serious. Especially the low temperature weather brought by Siberian high has swept through most parts of China. Ah, this Siberian high and the humid climate in eastern China will cause snowfall and bring abundant rainfall.

Third, people are still immersed in autumn. Finally, people are still immersed in autumn, because the temperature will be higher this autumn than in previous years. But it is precisely this hot autumn that makes us often ignore the arrival of winter, so at this time we feel that this winter will be very cold.
