The continuous high temperature weather in the south has basically ended. Why is this summer not normal?

This summer is so hot that no one will forget it. There is a large area of continuous high temperature weather in the south, which is basically over now, mainly because the environment has been affected and related to global warming.

According to some data, the continuous high temperature weather in most parts of the south has basically ended, mainly due to the abnormal subtropical high in the western Pacific, which has become particularly strong, resulting in the high temperature weather this summer. This is also the most direct reason, and it is also related to the overall trend of global warming, because on the seasonal scale, it is also related to the SST anomaly in the northwest Pacific. On August 30th, according to some information from the Central Meteorological Observatory, the yellow warning of high temperature has been lifted, and the continuous high temperature weather in southern China has basically come to an end. This round of high temperature weather is the strongest high temperature weather since 196 1 year, which has a wide range and a long time, and belongs to extreme weather, and has set a new historical record.

The main reason is that the subtropical high in the western Pacific is unusually strong this year, resulting in continuous high temperature weather. You may not know what a subtropical high is and why it has become so strong. It is abnormal because the subtropical high is particularly strong. In the Sichuan Basin, Shaanxi and Chongqing have recently ushered in heavy precipitation, so the high temperature weather has finally subsided.

This summer, there was also a high temperature heat wave event. At the earliest, its whole time was very early, its duration was relatively long, its influence scope was very large, and its comprehensive strength was very strong. According to meteorological monitoring, this regional high temperature event lasted for 79 days, covering 5 million square kilometers, and high temperature weather above 40℃ occurred in many provinces, which affected people's normal life.
