Analysis of the reasons why it is not cold this year in 2022

The reason why it is not cold this year in 2022 is global warming.

In 2022, with the trend of global warming, the probability of freezing is low, but when it is cold, the temperature is still low, so it is necessary to pay attention to keep warm. At present, it is not very cold in the south, and it feels not much different from the year before.

According to the forecast of China Landscape Bureau, the winter temperature in most parts of China this year is close to normal or higher than normal, and the probability of cold winter is almost zero. During the Chinese New Year, there are occasional days of low temperature, and other times are warmer than normal. But in fact, it does not rule out the change of temperature fluctuation in the times.

The reason of cold in winter

1, La Nina event

In April-May this year, the Institute of Gas Physics of Chinese Academy of Sciences assembled a simulator of the earth system in a scientific way, and predicted that La Nina events would occur in 2022-2023 for three years, and provided correct predictions to relevant departments. The latest outlook shows that the current La Nina situation will continue and grow in autumn and winter of 2022, and reach its peak in winter.

2. Global warming

At the end of September, the deputy director of the National Weather Center hinted at the regular press conference of China Landscape Bureau that the frequency of warm winters has increased since 1986 under the background of global warming. In the winter after La Nina, there are years when the temperature is low. Under the synergistic influence of La Nina event and high temperature Arctic Ocean, this winter, China's cold atmospheric activities are easy to continue, and it is easy to have staged low temperature and extreme cold events.
