Recently, many places in China have been hit by a cold wave, and many citizens have felt a strong sense of freezing. This is far from the "warmest year" of the National Climate Center, which has caused many people to wonder: "What about the warmest year, why is the cold wave so cold?"”
The National Climate Center explains that a warm winter does not mean that the temperature will be higher every time. In fact, the contrast between warm and cold winter temperatures is judged based on the average temperature over the entire period. For example, in the autumn of this year, most parts of China suffered a cold wave weather process, and the temperature fell off a cliff, which was much lower than the same period in history. However, if you calculate the average temperature for the whole of autumn, you will find that it is the highest since 1961, so it is considered the "warmest autumn".
So, in the context of global warming, why is the cold air in autumn and winter still so strong?The National Climate Center said global warming does not rule out the possibility of localized extreme cold weather. The trend towards a warming climate does not mean that winters will be as warm as spring every year. The climate system is a very complex system that is influenced by a variety of factors, including atmospheric circulation, ocean circulation, surface features, etc. As a result, in some years, cold air can still bring a strong sense of cold.
In addition, there is also some uncertainty about the winter temperature. Although the National Climate Center uses advanced climate models and data analysis techniques, it is still unable to accurately ** every arrival of cold air. This also means that in the process of tackling climate change, we need to be prepared to deal with all kinds of extreme weather.
In conclusion, the mystery of the cold wave behind the mild winter reveals the complexity of the climate system. In the context of global warming, we should not only pay attention to the overall climate trend, but also be vigilant against local extreme weather. As journalists, we will continue to monitor the latest developments in climate change and bring you accurate and comprehensive coverage.
