Some areas in the north have been hit by heavy rainfall, and the Tarim River in Xinjiang has long exceeded the police. Why is the climate so abnormal this year?

Heavy rainfall has continued in some parts of the north this year, with the Tarim River in Xinjiang exceeding the alert for a long time. As the longest inland river in China, the middle and upper reaches of Tarim River have approached or exceeded the warning flow in many places since August this year, which is easy to cause geological disasters such as floods. Although the peak flow of Tarim River has been reduced through the coordinated control of the local emergency department and the relevant departments of the Ministry of Water Resources, some major sections are still in the state of over-alert and in the flood control stage. Faced with such an abnormal climate, some experts explained that the floods in the north were caused by continuous high temperature and heavy precipitation in mountainous areas.

This statement is easy to understand, because the flood in Tarim River is a mixed flood, mainly because the continuous high temperature weather melts the snow and ice on the mountain, and these waters and rainfall together form flash floods. Similar to other areas. The temperature in the northern region itself is low, and many towering peaks have traces of ice and snow. Once there is continuous high temperature for several days, it will melt the ice and snow, just like the source and runoff of Tarim River show an increasing trend at the same time. The melting of ice and snow itself will cause certain difficulties for local flood control.

In addition, under the influence of global climate change and high-intensity human activities, unusually high temperature weather occurs every year, but it is more frequent this year. The fundamental reason is that the over-exploitation and non-environmental protection of the earth's resources are killing environmental resources and seriously affecting the global climate. Therefore, it will increase the probability of extreme weather, such as short-term heavy rainfall in the north and unusually high temperature in the country.

Global warming may also be an important cause of climate anomalies this year. There is no doubt that global warming has had a serious impact on our lives from the large-scale melting of ice and snow in the Antarctic and Antarctic in the past few years to the increasing temperature year by year, and all this is entirely due to the high-intensity activities of human beings themselves.
