5. Views of Meteorological Experts
Zhang Ming (pseudonym), chief forecaster of the Sichuan Provincial Meteorological Bureau, said: "Chengdu's extreme low temperatures have shown a slight fluctuation trend in recent years and have not yet exceeded the historical extreme. However, it should be noted that as the urban heat island effect intensifies, the temperature difference between urban and suburban areas is expanding. Citizens need to pay attention to specific regional weather forecasts when traveling."
According to data from the Chengdu Meteorological Observatory, the average temperature in Chengdu from December to February in the past 10 years was 6.5°C, 0.8°C higher than in the 1990s. However, the frequency of extreme low temperature events has increased, which is consistent with global climate change trends.
Conclusion
As a typical southern city, Chengdu's winter low temperatures are numerically less severe than those in the north, but the special wet and cold climate still brings challenges to citizens' lives. By understanding historical data and scientific cold protection knowledge, citizens can better cope with cold weather in winter. It is recommended to pay attention to the official weather forecast, make reasonable arrangements for travel and daily life, and spend the cold winter warmly.
