Are all the weird weather this year caused by El Nino?

This question should be answered from different angles. First of all, we should understand the relationship between weather and climate. The biggest difference between them is the different time scales. It can be said that the weather is aimed at a certain time, and the climate refers to a state of the weather in a period of time. Teacher Zhang's question should also be answered from two angles. First of all, El Nino is an abnormal increase in seawater temperature in the equatorial Pacific Ocean. This seemingly unrelated event has a subtle influence on the weather through the interaction between the air and the ocean. The influence of El Nino on winter in China is mainly caused by warm winter phenomenon. However, the phenomenon of warm winter here can only be seen from the average temperature of the whole winter and the whole country, and can not refer to the weather conditions in a certain place or at a certain moment. From another point of view, that is, from the weather point of view, El Niñ o phenomenon not only causes warm winters, but also affects various extreme phenomena. The process of these effects is very complicated, but in general, it is because the existence of El Niñ o destroys the overall stability of atmospheric circulation, and then a series of effects appear, which eventually leads to extreme weather phenomena. This winter, the heavy snow and cooling in June in the north, 165438+ 10 broke the historical extremes in many areas. Some people may ask, doesn't El Nino bring warm winter? Why is it so cold? It is precisely because of the circulation adjustment brought by El Nino that these snowfalls have cooled down, and the warm winter depends on the average state of the national temperature. In the south, especially in the southwest, the continuous precipitation since this winter has even triggered geological disasters in some areas. From the point of view of precipitation, every weather process is different, but the "behind-the-scenes" of these weather processes may also be El Niñ o. It is speculated that the circulation adjustment may have affected the distribution of southwest airflow, introduced the warm and humid Indian Ocean Bay of Bengal airflow into China, and brought precipitation. Talking too much, I don't know what I'm talking about. Generally speaking, from the climate point of view, El Nino will cause high temperature in winter in China. From the weather point of view, El Nino indirectly affects every weather process through its influence on circulation, which will bring many extreme weather.
