2 1 century "triple" La Nina appeared for the first time, what impact will it bring to the regional climate in autumn and winter in China?

First, it will change the climate in autumn and winter. Meteorology refers to the phenomenon that the sea surface temperature in the eastern and central equatorial Pacific becomes extremely cold in a large range. After La Nina event, the global climate will have different degrees of abnormal characteristics. so this is it？ Triple? The beginning of La Nina incident. La Nina events in the equator, the Middle East and the Pacific continue. The National Climate Center predicts that the La Nina event in the equatorial Middle East Pacific will last until the winter of 2022/2023.

Secondly, if the long-term La Nina phenomenon is the direct result of human-induced climate change. This is a natural phenomenon. Under normal conditions in the Pacific Ocean, the trade winds blow westward along the equator, bringing warm seawater from South America to Asia. In order to replace warm water, the process of cold water rising from the depths is called upwelling. El Nino and La Nina are two opposite climate patterns, which break these normal conditions. Scientists call these phenomena El Nino-Southern Oscillation (ENSO) cycles. Both El Nino and La Nina will have a global impact on weather, wildfires and ecosystems.

In addition, there will be heavy rains and floods. La Nina is a feature of the worsening drought in the Horn of Africa and southern South America, as is the above-average rainfall in Southeast Asia and Australasia. In summer, it suffered from continuous destructive rainfall, and a large area of its east coast, especially the northern part of NSW, was destroyed by floods. Coastal towns are still suffering from the wettest summer in 30 years and need billions of Australian dollars to make up for the losses.

You know, with the continuous development of global warming, the annual average temperature will be temporarily higher than the average temperature of 1850 to 1900 for at least one year, and the probability of this happening is 48%. This critical point of human climate of 1.5 degrees will be broken, and we will see a hotter earth. Of course, as the earth gets hotter, it will inevitably bring more climate effects. Don't rule out multiple climate systems? Critical point? . Extreme climate change will only lead to a more difficult situation in the future. It is not a good thing for us human beings. Extreme weather can lead to death.
