What is the reason for the extreme cold wave next year? 1- Cold air activities will be significantly strengthened in February next year, and the temperature in most parts of the central and eastern regions may be lower than that in the same period of normal years, so there is a greater possibility of staged extreme cold wave events.

What is the reason for the extreme cold wave next year? 1 According to the news of China Meteorological News Agency, the cold wave has recently brought "cliff-like" strong cooling and extensive rain and snow weather. Some people question whether the violent cold wave is hitting the face of global warming.

In this regard, Zhou Bing, chief expert of climate service of the National Climate Center, said that it is in the context of global warming that the frequency and intensity of extreme weather events such as high temperature heat waves, droughts, floods, typhoons and cold waves have increased. Global warming leads to more unstable climate and increased intensity of extreme cold events.

At present, the general trend of global warming has not changed. According to the Global Climate Statement 2020 issued by the World Meteorological Organization, 2020 is one of the three years with the highest global average temperature on record. The past five years (20 16-2020) and the past ten years (20 1 1-2020) are the hottest five years and ten years on record, respectively. Since 1980s, since 1850, each successive decade has been hotter than the previous one.

Is the average temperature in China still rising this year? Is it expected to be very cold this winter?

Zhou Bing said that China is a country with a remarkable monsoon climate. Winter is influenced by the East Asian winter monsoon, and strong cold air from polar regions or middle and high latitudes will affect China through multiple paths. According to the statistics of National Climate Center, the air activity was obvious in the year of La Nina event. The National Climate Center predicts that the cold air activities affecting China this winter will be frequent and strong, and the temperature in the central and eastern regions will be mainly cold.

This winter, the cold air affecting our country is frequent and powerful, which is not in contradiction with the global warming trend. Since the beginning of this year, the weather and climate in China have been complicated and abnormal. As of 10 year1October 27th, the national average temperature (12.7℃) is higher than that of the previous year 1. 1℃, which is the highest in the same period in history since 196 1 year. Climate warming is still the main theme of climate change in China and the world.

Global warming has changed the characteristics of global atmospheric circulation, and affected local climate through the interaction between air and sea. In addition, arctic warming is also an important reason for extremely cold weather. It is expected that the cold air activity will be significantly strengthened from June 5438 to February next year, and the temperature in most parts of the central and eastern regions may be lower than that in the same period of the previous year, so there is a greater possibility of staged extreme cold wave events. All localities should continue to guard against the adverse effects of low-temperature weather, do a good job in dispatching and supplying energy such as coal, electricity, oil and gas, do a good job in ensuring Spring Festival travel rush, and strengthen fire prevention in forests, grasslands and urban-rural fringe areas.

What is the reason for the extreme cold wave next year? The recent cold wave has brought "cliff-like" strong cooling and a wide range of rain and snow weather. In this regard, Zhou Bing, chief expert of climate service of the National Climate Center, said that it is in the context of global warming that the frequency and intensity of extreme weather events such as high temperature heat waves, droughts, floods, typhoons and cold waves have increased.

Global warming leads to more unstable climate, and the intensity of extreme cold events is increasing. Global warming has changed the characteristics of global atmospheric circulation, and affected local climate through the interaction between air and sea. In addition, arctic warming is also an important reason for extremely cold weather.

It is predicted that 1- the cold air activity will be obviously strengthened in February next year, and the temperature in most parts of the central and eastern regions may be lower than normal, so there is a greater possibility of staged extreme cold wave events. All localities should continue to guard against the adverse effects of low-temperature weather, do a good job in dispatching and supplying energy such as coal, electricity, oil and gas, do a good job in ensuring Spring Festival travel rush, and strengthen fire prevention in forests, grasslands and urban-rural fringe areas.

Since the beginning of this year, people have obviously felt that some extreme weather is frequent. What is the reason behind this? Zheng Zhihai, chief expert of National Climate Center of China Meteorological Bureau, said that frequent extreme weather and climate events are closely related to global warming to some extent. One of the main manifestations of global warming is that different regions have different warming rates. For example, the warming rate in the Arctic region and our plateau region is obviously higher than the global average. It is precisely because of the change of thermal difference, especially the influence of Arctic amplification effect, that the longitude of circulation in our middle and high latitudes is obviously increased, that is to say, the instability is obviously increased, which makes the frequency and intensity of such extreme events obviously increase.

Global warming is a general trend. Is there any effective way for mankind to reverse the trend of global warming? Some people think that global warming has become an indisputable fact. Although all countries in the world are actively trying to find ways, from a certain point of view, they have to rely on today's black technology-carbon capture technology. This technology is simply equivalent to our air purifier, but the volume of the two is different.

What is the reason for the extreme cold wave next year? Before and after beginning of winter, a large-scale strong cold wave swept through the central and eastern parts of China. At the same time, 202 1 United Nations Climate Change Conference is being held in Glasgow, England. The topic is how to reduce greenhouse gas emissions such as carbon dioxide and control global warming.

Faced with the seemingly "contradictory" problem, people can't help asking: Why should we control global warming? Isn't it nice to be warmer in winter? Is the strong cold wave the "face-beating" of global warming? In fact, there is no contradiction between strong cold wave and global warming. Global warming means that the global annual average temperature is generally high, and there will still be cold and warm fluctuations in individual years, and there will be strong cold waves. In fact, it is in the context of global warming that the frequency and intensity of extreme weather events such as high temperature heat wave, drought, flood, typhoon and cold wave are increasing. In the context of global warming, extreme low temperature events are common in recent years.

At present, the general trend of global warming has not changed. According to the Global Climate Statement 2020 issued by the World Meteorological Organization, 2020 is one of the three years with the highest global average temperature on record. The past five years (20 16-2020) and the past ten years (20 1 1-2020) are the hottest five years and ten years on record, respectively. Since 1980s, since 1850, each successive decade has been hotter than the previous one.

Then, why do extreme cold events occur from time to time and the intensity is often very strong in the context of global warming? This is because global warming makes the climate more unstable and the intensity of extreme cold events increases. Global warming has changed the characteristics of global atmospheric circulation, and affected local climate through the interaction between air and sea. In addition, arctic warming is also an important reason for extremely cold weather. The warming rate of the Arctic region is 2-3 times that of the whole world, and it has become the most sensitive region to global climate change. Under the warming trend, the Arctic vortex will weaken, and the cold air in the polar vortex will split south, which will obviously reduce the temperature in the relevant areas.

Some people may think that no longer strictly controlling global warming, making the cold winter warmer, can make everyone feel less cold, but that is not realistic. The Blue Book of Climate Change in China (202 1) shows that the number of extreme low temperature events in China has generally decreased in recent years, but the intensity of extreme low temperature events has not weakened. In other words, with global warming, it is as hot or cold as a seesaw.

All kinds of extreme weather once again sounded the alarm-climate change characterized by global warming has brought many impacts and risks to the natural ecological environment and human economy and society, which is one of the most severe challenges facing the world. It is still extremely necessary to strengthen prevention and response capabilities and reduce the losses caused by climate change.

In the context of global warming, society and the public often ignore the prevention and response to extreme cold events. However, extreme cold events are likely to have a serious impact on production and life, and we still need to attach great importance to them. It is necessary to strengthen measures to deal with extreme cold events, improve departmental emergency linkage mechanism, strengthen information sharing, improve joint response capabilities, and minimize or reduce adverse effects and hazards. At the same time, it is necessary to strengthen the study of disaster-causing mechanism, improve the early warning ability, improve the level of climate change monitoring, prediction and impact assessment, and further improve the disaster risk early warning ability.

At present, we should continue to guard against the influence of low temperature weather in winter. It is predicted that the cold air activity will be significantly strengthened in June 5438+0-February next year, and the temperature in most parts of the central and eastern regions may be lower than normal, which is easy to cause staged extreme cold wave events. All localities should continue to guard against the adverse effects of low-temperature weather, do a good job in dispatching and supplying energy such as coal, electricity, oil and gas, do a good job in ensuring Spring Festival travel rush, and intensify fire prevention in forests, grasslands and urban and rural areas.
