Is it cold this winter?

From April to May this year, the Institute of Atmospheric Physics of the Chinese Academy of Sciences used the earth system simulator of scientific instruments to predict that La Nina events will occur for three consecutive years in 2022-2023, providing accurate prediction and early warning for relevant departments. The latest forecast results show that the current La Nina state will continue and develop in autumn and winter of 2022, reaching its peak in winter. It is predicted that the temperature in some parts of northern China is slightly lower this winter, which may lead to staged low temperature due to the influence of staged cold air, and the possibility of extreme cold wave outbreak is high; Disasters such as low temperature, freezing, rain and snow may exist in some areas in the south, so it is necessary to be vigilant and raise awareness of prevention.

This winter is a cold winter, because under the synergistic influence of La Nina event and the warm Arctic Ocean, the cold air activity in China is easy to continue to be strong this winter, and it is easy to have staged low temperature and extreme cold events. For the early warning of extreme low temperature events, it is necessary to strengthen short-term weather forecast and climate trend forecast for more than two weeks, and improve the prevention and early warning ability of freezing rain and snow disasters. At the same time, agriculture, animal husbandry, energy and transportation industries need to pay close attention to the early warning of freezing rain and snow disasters and formulate effective preventive measures and emergency plans.
