1.Cause analysis:The Arctic vortex splits and moves south, cooperating with the transport of water vapor on the east side of the Tibetan Plateau, creating a "moist and cold bomb" effect.
2.Trend forecast:Data from the Sichuan Provincial Climate Center shows that the frequency of extreme low temperature events has increased by 23% in the past 20 years, but the intensity of a single cold wave has fluctuated and declined.
3.Defense suggestions:Heating facilities need to be improved in high-altitude areas, cold-resistant crop varieties should be promoted in agricultural areas, and transportation departments need to establish a hierarchical early warning mechanism.

6. Prospects for future climate evolution
According to the "2021-2030 Climate Blue Book" released by the Sichuan Provincial Meteorological Bureau, the average winter temperature in the Western Sichuan Plateau is expected to rise by 1.2-1.8°C, but extreme low temperature events may still occur frequently. This characteristic of "overall warming and local sudden cooling" is closely related to circulation anomalies in the context of global climate change.
This article presents structured data to help readers fully understand Sichuan's low temperature extremes and their social impacts. It is recommended that the public obtain real-time warning information through the "Sichuan Meteorological" official APP and take scientific protection.
