Poyang Lake and Dongting Lake have recently shrunk by 66%. Why is the weather so abnormal this year?

0 1 is caused by the attack of subtropical high in the western Pacific. This year's weather is really abnormal, with heavy rainfall in many areas. In fact, the so-called western Pacific subtropical high is a permanent high-pressure circulation system over the Pacific Ocean, which will really have a great impact on China's climate and weather. If the subtropical high in the western Pacific combines with the water vapor from the Indian Ocean, it will eventually form rainfall conditions, and with the action of cold air in the north, there will eventually be large-scale rainfall.

In addition to heavy rainfall, drought occurred in some areas this year, which is actually related to the subtropical high in the western Pacific. Because when the tropical high meets the special weather system in the western Pacific, there will be a strong subsidence inversion on both sides, which makes the water vapor unable to form rainfall, and a long time will lead to a large-scale drought, which is one of the main reasons for the drought and high temperature in northern China.

It is caused by global warming. The western Pacific subtropical high we mentioned above is not the most fundamental cause, but the fundamental cause of abnormal weather is global warming. With the rapid pace of global warming, the subtropical high events in the western Pacific will naturally become more and more frequent, which will have a greater impact on China's domestic climate and weather. In this case, whether it is flood, drought or other extreme natural disasters, the probability of occurrence will gradually increase.

You know, global warming seems to be a foregone conclusion now, and countries can't stop or change it for a while. In this context, not only the subtropical high in the western Pacific will have an impact on people's lives, but also other extreme weather will follow, which will have a greater impact on our lives.
