With the emergence of triple La Niña, how cold will the weather be this year?

Triple La Niña appears. La Niña and El Niño are brothers and sisters with very different personalities. La Niña has always been the counterpart of "cold". The National Oceanic and Atmospheric Administration defines La Niña as a periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific. La Niña typically occurs every three to five years or so, sometimes for several years in a row.

We are also confused about the mechanism of La Niña phenomenon for three consecutive years. La Niña is a very complex climate phenomenon caused by the interaction of air and ocean, but its impact on global weather and climate is recognized, producing abnormal changes in water temperatures in the equatorial Pacific. In the context of global warming, the tropical Indian Ocean, Atlantic Ocean, and Western Pacific are warming at a relatively rapid rate, and the non-uniform trends in interdecadal and long-term warming of sea temperatures in the three oceans are conducive to the continued occurrence of La Niña through the influence of the ocean basins. The temperature in southern China is higher, which is caused by the sub-high pressure. The temperature in the northern region is the highest since October. When the temperature in Hunan, Guangxi, Jiangxi and other places is more than 30 degrees, there is no intention to cool down. By October 10, the cold air After the attack, the temperature in Hefei, Changsha, Jinan and other China entered the autumn night state.

Coupled with the arrival of typhoon Luo Pan, the temperature in the coastal areas of Hainan and Guangdong has dropped significantly, falling below 20 degrees. Now there is another wave of cold air coming, which is expected to last for 14-17 years, or will This is the strongest cold air in the second half. It is expected to affect Jianghan, South China, Jianghuai, and Jiangnan, and may cause a secondary cooling. Therefore, the winter of 2022 is expected to be a cold winter. Judging from the number of songs from the winter solstice to the Chinese New Year, the Spring Festival in 2022 happens to be the end of the fifty-nine days. According to normal rules, it should not be very cold. However, the weather this year is unusual. Based on current weather trends, the Spring Festival in 2022 is expected to be cold.
