Recently, the central and eastern parts of China have encountered rare low temperature and freezing weather, snowfall, freezing, and strong winds have swept all over the country, and life has fallen into a lot of trouble. The good news is that this wave of cold freezing is about to pass, the temperature is starting to rise, and the feeling of returning to the south is becoming more and more obvious. Let's unravel this fascinating meteorological puzzle from a scientific perspective.
First of all, why is the temperature rising after the cold air?The main reason behind this is that the departure of cold air makes the warm and humid air flow rapid**, causing the temperature to rise and the air humidity to increase, commonly known as "returning to the south of the sky". Cold air is a high-density, high-pressure, low-temperature air mass, while warm and humid airflow is a low-density, low-pressure, high-temperature air mass, and the interaction between the two leads to drastic changes in temperature, which is a typical climatic phenomenon in winter in China.
Secondly, the extent and magnitude of the temperature rise are affected by the intensity and extent of the cold air and the adjustment of atmospheric circulation. The intensity and extent of cold air is determined by a variety of factors, including temperature differences, topography, seasons, etc. At the same time, atmospheric circulation is the shaper of global climate characteristics, and its adjustment affects anomalies and fluctuations in temperature. According to the analysis, the peak period of cold wave in China is usually from November to February, during which the atmospheric circulation in the northern hemisphere is adjusted, and the cold air activity is frequent and strong. With the change of seasons, the influence of cold air gradually weakens, and the range of temperature rise expands.
Finally, the rise in temperature has also degraded China's climate change trend. Rising temperatures are one of the manifestations of this, and the average annual temperature in our country has risen by 09. The rate of rise has been even faster in the past 30 years. This adversely affects snow and ice melting, sea level rise, heat events, and more. Changes in precipitation and frequent climate disasters are also manifestations of climate change trends, which pose challenges to agriculture, water resources, and ecosystems.
In summary, the mystery of the temperature rise stems from the interaction of cold and warm airflows and the adjustment of atmospheric circulation. These laws help us understand the inner workings of meteorology, while also reminding us of the profound impact of climate change on our lives and developments. Strengthening climate monitoring and early warning, improving climate adaptation and mitigation capabilities, and actively participating in international cooperation are our common responsibilities to address climate challenges and protect our common home. Let's explore this wonderful and complex meteorological mystery together and work towards a better future.
