　　Xinhua News Agency, Beijing, December 19th Special feature: Finding the way in the changing situation — — Review of the International Situation in 2019

　　Xinhua News Agency reporter Ban Wei

　　In 2019, the second decade of the 21st century is coming to an end.

　　This year, the world was full of chaos and challenges: the game between big countries intensified, the governance deficit increased, and the world economy continued to slump. The characteristics of the accelerated evolution of the "great change in a hundred years" are more obvious: the dispute between multilateralism and unilateralism is more acute, protectionism and populism are surging against the current, and power politics and bullying are rampant everywhere.

　　This year, globalization and multipolarization are still moving forward with heavy burdens in twists and turns, and a new round of scientific and technological revolution and industrial transformation is emerging. More and more countries are seriously thinking about what choices should be made in the contest between cooperation and confrontation, multilateralism and unilateralism, and openness and closure.

　　The Sound and the Fury

　　The change of the "2019 edition" shows that the game between big countries has obviously warmed up.

　　Near the end of the year, NATO held a "70th birthday party". However, American leaders repeatedly complained that "NATO is out of date", demanded NATO member countries to substantially increase their military spending, and called the EU an "enemy" of trade. France said that NATO experienced "brain death" and so on, which made the party "play inharmony", and the wrestling of all parties increased. NATO tasted the birthday cake with "trust deficit".

　　The German newspaper Le Monde said: "NATO is now threatened from within." Gusev, director of the Russian Institute of Strategic Planning and Forecasting, said: "The complicated relationship between the United States and NATO allies complicates the current international relations."

　　This is the latest epitome of the widening rift in traditional relations in western countries. In one year, the G-7 held a summit, but only issued a "one-page statement" that lacked substance, highlighting internal differences and weak influence. As the world’s largest economy, the United States has repeatedly opened new fronts in the global trade war. After announcing the imposition of tariffs on EU aviation and agricultural goods, it plans to retaliate against French digital tax … …

　　During the past year, Russia hoped that Russia-US relations would return to normal, but frankly this situation has not yet appeared, and relations with the United States are "regressing and getting worse and worse". Although Russia and Europe have released in good faith from time to time, improving relations is facing challenges. Japan’s Diplomatic magazine said that "cold peace" seems to be becoming the new normal of bilateral relations.

　　The change of the "2019 edition" shows that anxiety, tearing and chaos are staged in many parts of the world, and the uncertainty is further increased.

　　Political struggles in Latin American countries have intensified, and governance problems have become prominent; The confrontation between Iran and the West and the Syrian conflict are intertwined, which intensifies the turmoil in the Middle East and presents a peace deficit. Britain’s "Brexit" has been delayed for a long time, revealing social tears and institutional difficulties; The United States continues to "retreat from the group" and tries to make the United States "great again" through unilateralism and protectionism, which has impacted the international order.

　　The change of the "2019 edition" is also manifested in the continued downturn of the world economy. Georgieva, the new managing director of the International Monetary Fund, said that trade disputes, Britain’s "Brexit" and the uncertainties brought about by geopolitical tensions are inhibiting the global economic growth potential. IMF predicts that the global economic growth this year will be the lowest since the international financial crisis in 2008.

　　The sunshine behind the dark clouds

　　In the changing world, people can still touch the development force in the deep dive. The light coming out of the clouds still indicates the general trend of global development.

　　In the face of changes, "everyone is also looking for new alternatives and ways out." Zheng Yongnian, a professor at the Institute of East Asian Studies at the National University of Singapore, pointed out that it is a general trend for more countries to jointly promote multilateralism while some western powers are pursuing economic nationalism and unilateralism.

　　This year, in the face of counter-current, globalization is making efforts to take new steps. On November 4th, the Third Regional Comprehensive Economic Partnership Agreement (RCEP) leaders’ meeting issued a joint statement, announcing that the 15 member countries had concluded all text negotiations and virtually all market access negotiations. The publication of the joint statement marks a major breakthrough in the construction of the East Asia Free Trade Area with the largest population, the largest membership structure and the greatest development potential in the world, highlighting that multilateralism and free trade are still the mainstream in the world.

　　Yu Jie, a senior researcher at the Royal Institute of International Affairs, believes that the breakthrough in RCEP negotiations plays an exemplary role in solving the development problem of economic globalization and sets an example for developing countries to seek the right to speak in global governance.

　　Earlier, the construction of a free trade area on the African continent was officially launched, and the "marathon" negotiations between MERCOSUR and the EU Free Trade Agreement finally came to fruition. Today, with the increasing downside risks of the world economy, more and more countries realize the importance of maintaining free trade and a rules-based multilateral trading system for hedging risks and seeking growth.

　　This year, the world saw the trend of the continuous development of multipolarization. In the great changes, emerging markets and developing countries, represented by BRICS countries, are constantly rising, which has injected strong impetus into the reform of the global economic governance system and effectively promoted the process of world multipolarization.

　　This year, the world saw that a new round of scientific and technological revolution and industrial transformation was emerging. The limit of growth has always been a haze lingering over the development of human society. Nowadays, people are increasingly seeing the bright future of innovation-driven solution to the development difficulties.

　　In the past year, the world began to enter the stage of 5G commercial deployment, and the transformation of old and new kinetic energy accelerated; AI intelligence in all fields has provided a broad blue ocean for economic development; New breakthroughs have been made in quantum computing, and its prospects are limitless. The new scientific and technological revolution and industrial transformation have provided more opportunities for countries to achieve leap-forward development, and also made it an inevitable logic for countries to increasingly blend interests, share common destiny and win-win cooperation.

　　人类群星闪耀时

　　回望2019年的国际风云，中国理念、中国方案、中国贡献，作为顺应和推动全球发展大势的重要力量，在乱局中引领方向。

　　中国主张和担当为多边主义、多极化和完善全球治理注入强大正能量，推动构建新型国际关系。

　　一年间，国家主席习近平7次出访，主持4次主场外交。元首外交维护世界和平，促进共同发展，捍卫多边主义。从二十国集团领导人峰会到中法全球治理论坛，从“一带一路”国际合作高峰论坛到金砖峰会，中国维护多边主义、加强全球治理、推动世界多极化主张引发广泛共鸣。国际上的事应该由大家商量着办，不能由一国或者少数几个国家说了算，成为越来越多国家的共识和心声。

　　谈及中国在当今世界格局中的作用和地位，法国前总理拉法兰说，中国扮演着非常重要的角色，是世界经济增长的引擎。中国参与构建新型多边主义，助推亚洲以及非洲在国际体系中的地位提升。

　　中国以实际行动，为建设开放型世界经济作出表率。

　　第二届中国国际进口博览会在6天里，累计意向成交711.3亿美元。“越办越好”的进博会，交易的是商品和服务，交流的是文化和理念，种下的是开放、合作、共赢的种子。

　　布鲁金斯学会约翰·桑顿中国中心主任李成认为，不论是“一带一路”建设，还是第二届中国国际进口博览会，中国都更多体现出包容性增长理念，强调共同发展、共享经济，这表明中国并不是一花独放，而是愿与世界共同发展。

　　中国倡导的构建人类命运共同体理念，为追寻人类文明的群星闪耀指明方向。

　　“这是最好的时代，这是最坏的时代。”在一首今年风靡网上的歌曲中，一名中国草根歌手借用英国作家狄更斯的名句，唱出人们对当今矛盾世界的感悟。

　　就世界如何应对风险与挑战、寻求平等与共赢、消除傲慢与偏见，中国给出答案：既需要经济科技力量，也需要文化文明力量。在构建人类命运共同体的目标引领下，倡导多元文明共生并进，用文明对话促进沟通与理解，将让人类前进的道路越走越宽广。

　　“当前，世界多极化、经济全球化、文化多样化、社会信息化深入发展，人类社会充满希望。”习近平主席今年5月在亚洲文明对话大会开幕式上的这番话，针对充满不确定性的当今世界，发出提振信心的强音。（参与记者：栾海、张骁、王丽丽、桂涛、徐永春、韩茜、刘品然）

Original title: How does love affect our lives?

Love is one of the most beautiful emotions in life, which has a far-reaching impact on our lives.

First of all, love can bring happiness and happiness. When we fall in love, our brains release chemicals such as dopamine, which makes us feel happy and happy. These chemicals can make us feel more relaxed and happy, so that we are full of enthusiasm and vitality for life. Secondly, love can also bring growth and change. When we fall in love with someone, we will work hard to better meet each other’s expectations, so as to promote our continuous progress and growth. At the same time, we will be inspired and influenced by each other’s advantages, so as to change our own shortcomings and deficiencies. Finally, love can also bring pain and trouble. When we lose love, we will feel heartache and loss, and even lose confidence and hope in life. In addition, love will also make us face various challenges and difficulties, such as communication, trust, mutual support and so on.

Love is a double-edged sword, with both good side and painful side. Let’s learn to face the challenges and difficulties in love while enjoying the happiness and happiness brought by love.

Editor in charge:

　　China’s famous world cultural heritage — — The Grand Canal is a great water conservancy project created by the ancient people of China. It consists of three parts: the Beijing-Hangzhou Grand Canal, the Sui-Tang Grand Canal and the East Zhejiang Grand Canal. It starts from Beijing and Tianjin in the north, reaches Jiangsu and Zhejiang in the south, and spans eight provinces of Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, Jiangsu and Zhejiang. It is the north-south traffic artery in ancient China.

　　In 2019, the Outline of Cultural Protection, Inheritance and Utilization Planning of the Grand Canal was promulgated, and eight provinces along the Grand Canal were deployed to promote the construction of the Grand Canal National Cultural Park. At present, 73 key projects along the route are progressing smoothly, and related museums, cultural parks and sites have achieved initial results. The ancient canal is showing new vitality.

　　Beijing Section of the Grand Canal: Inheriting History and Creating the Future

　　The history of the Grand Canal in Beijing can be traced back to Yongji Canal dug in Sui Dynasty. After the water source project of Tonghui River was implemented in Yuan Dynasty, the Beijing-Hangzhou Grand Canal was connected. In the Ming and Qing dynasties, the Grand Canal route of the Yuan Dynasty was basically followed. But later, due to the diversion of the Yellow River and the development of railway transportation in history, the Grand Canal gradually turned from prosperity to decline. However, it is undeniable that the political, economic and cultural exchanges linked by the Grand Canal have become a spectacular and brilliant page in the history of Chinese civilization. Now, the Beijing section of the Grand Canal is full of vitality.

　　The Beijing section of the Grand Canal takes Baifu Spring and Yuquanshan Springs as water sources, pours into Kunming Lake of the Summer Palace, passes through the long river, introduces Shichahai, passes through the old Yuhe River and Tonghui River, and flows into the North Canal. Among them, Tonghui River and Tongzhou section of the North Canal are all rivers of the Beijing-Hangzhou Grand Canal. Relying on the Grand Canal, the development of cultural belt, ecological belt and tourism belt is on the rise.

　　Chen Xibo, Executive Director of Tongzhou Grand Canal Research Association:From the perspective of the Grand Canal, it contains many cultures, such as water transport culture, dock culture, folk culture, and many landscape cultures, which are too numerous to list. These cultures are displayed on both sides of the canal, which is very conducive to giving full play to the cultural inheritance function of the grand canal.

　　At present, Beijing is accelerating the construction and protection of the Grand Canal National Cultural Park, which is based on the canal water system, linked with the canal culture and integrated with natural ecology and social and economic factors.

　　Chen Xibo, Executive Director of Tongzhou Grand Canal Research Association:Cultural heritage can be better protected, and the splendid Millennium Canal culture can be displayed, which is conducive to the management and protection of the entire water system of the Grand Canal, making the water on both sides of the strait clearer, the trees greener and the sky bluer, and also conducive to the development of cultural tourism industry on both sides of the strait. The canal will live. Because we can not only understand the culture, but also feel the customs on both sides of the Grand Canal through cultural tourism.

　　Since 2017, a number of landmark projects have been launched in Beijing: the retreat and renovation of sites along the canal, the comprehensive management of rivers such as the Xiao Taihou River, the establishment of a national 5A-level scenic spot in Tongzhou Grand Canal, and the navigation of cruise ships in Tongzhou section of the North Canal for 11.4 kilometers.

　　Near the old canal road, three new cultural landmarks — — The Grand Canal Museum, Theatre and Library will be built into a Beijing Grand Canal National Cultural Park with capital standards, Beijing characteristics and the weather of the times.

　　Tan Xuxiang, Director of Beijing Municipal Development and Reform Commission:Up to now, the monitoring of the Grand Canal in Beijing has been completed for ten sections, four lakes and twenty-eight sections, and the water environment quality has reached the requirements of the water environment functional zone. The cultural protection along the Grand Canal has also been strengthened, and the protection and utilization of a number of historical sites and remains have been fully launched. So far, the first phase of the Beijing section, 11.4 kilometers, has been completed, and the second phase will be completed in June this year, thus promoting the perfect integration of culture, tourism and the city in the Grand Canal Cultural Park. In the next step, we will strive to improve the ecological, cultural and environmental pattern of the Grand Canal, making it a symbol of the high-quality development of the sub-center and a green paradise for the happy life of ordinary people.

　　A new chapter on the context of the Millennium Canal.

　　The Grand Canal is a great project created by China in ancient times, and it is also a cultural symbol of China with extensive influence in the world. Beijing is accelerating the construction of the Grand Canal National Cultural Park. During the May Day period, Tongzhou Grand Canal Forest Park became a popular place for citizens to go on holiday.

　　Headquarters reporter Wang Shengdong:I am now in the Grand Canal Forest Park. According to past experience, the park authorities estimate that the number of visitors here may reach about 300,000 during the May Day holiday. It can be said that the Grand Canal Forest Park has become a good place for foreign tourists and Beijing residents to spend their holidays. The river section where I am located is also a part of the Grand Canal National Cultural Park under construction in our country, and now it belongs to Tongzhou section of Beijing.

　　A river: the cruise ship will sail soon at the end of June

　　Among all the familiar sections of the Grand Canal, Beijing has two sections, one is Tonghui River, and the other is Tongzhou Section of the North Canal.

　　Today, the first thing I want to introduce is a river. The entire Tongzhou section of this river is 41 kilometers. It is necessary to complete the navigation of the whole line of cruise ships by the end of June this year. This is a prosperous time that many people have been looking forward to for many years, because the existing river section is only 11.4 kilometers, which can meet the needs and experiences of more people to visit the canal culture after the whole navigation.

　　This river is divided into two parts, but after navigation, there will be three modes of sightseeing: one short, one long and one night sailing.

　　Scenery all the way: Tongzhou Grand Canal is creating a national 5A scenic spot.

　　Now, at the starting point of the North Canal, that is, the intersection of the five rivers, there are familiar scenic spots of three temples and one tower, as well as the Tongzhou Grand Canal, which is connected in series by the Canal Park and the Grand Canal Forest Park. At present, a national 5A-level scenic spot is being created.

　　A Fan: Witness of Water Transport Culture

　　You can see the symbols on this fan in the picture above. It is very strange. The original and copy of the fan are now quietly kept in Tongzhou Museum. This fan is an important witness to the canal water transport culture. In the Ming and Qing Dynasties, in order to ensure the safety of transporting the bridge from the south to Beijing, a non-official and non-civilian organization was derived. The personnel in the organization were called grain brokers, who checked the quality of the bridge. If relevant officials found that there was a problem with the quality of grain, they could check the responsibility through the secret symbols drawn on the grain bags by these brokers. So this fan was also called the QR code or barcode at that time.

　　Such a traceability system can be said to be an early traceability system in our country at present.

　　One line: 17 sites have been retired for repair and protection.

　　All large-scale landscape sites and sites along the canal have been properly protected, including 17 heritage sites and sites such as Baifuquan, manjuji and Baliqiao, which have been cleared, repaired and protected.

　　A feast: A number of Grand Canal cultural signs will appear.

　　Along the Grand Canal, there are not only the wisdom of our ancestors, but also the achievements of today’s people. Now three new cultural landmarks are about to rise. Now they are under intensive construction, and the museums, theaters and libraries in Tongzhou will become new landmarks in the future.

　　In addition, people are familiar with the digital experience such as the champion cultural exhibition, the map of the Luhe River, and even the workshops of various intangible products, which are now spread out on the banks of the canal.

　　Tianjin Section of the Grand Canal: Ecological Improvement and Cultural Continuation

　　As an important transportation hub of the Grand Canal, Tianjin is known as the "city carried by the Canal". The formation, development and prosperity of Tianjin city are closely related to the Grand Canal.

　　The Tianjin section of the Grand Canal starts from Muchang Gate in wuqing district in the north and ends at Jiuxuan Gate in Jinghai District in the south, with a total length of 182.6 kilometers, including North Canal, South Canal, Haihe River and Ziya River.

　　According to the distribution of river courses and heritage resources, wuqing district, Beichen District, Hebei District, Hongqiao District, Nankai District, Xiqing District and Jinghai District in Tianjin are the core areas where the Grand Canal flows.

　　The tourism resources on both sides of the Grand Canal are rich and diverse, with six main categories, including biological landscape, ruins, buildings and facilities, and a total of 275 resource products, among which the types of buildings and facilities account for the highest proportion.

　　Follow the aerial camera from the birthplace of Tianjin — — Sanchahekou started to set out, passing through many historical and cultural blocks such as Laochengxiang, Guwen Street, Juyi Street and Haihe River. Beiyang Garden and Wenjin Garden, which have just been completed in recent two years, rely on canal resources to create an ecological landscape for the people to go out and see the scenery, enjoy flowers in four seasons and walk into the forest.

　　Following the aerial camera to wuqing district, Tianjin, the green and golden eyes add gorgeous colors to the canal this season.

　　Yang Longyue, Tianjin wuqing district Water Affairs Bureau:We are now located in an important water conservancy hub in Wuqing section of the North Canal, with a total of nine water structures. The one behind me is an important one called the 16-hole sluice, which undertakes the task of flood discharge and drainage during the flood season. In recent years, we have also planted more than 200,000 square meters of landscape plants such as Isatis indigotica and rape flowers on the basis of the original landscape of the North Canal in non-flood season, providing landscape belts for people to enjoy and play.

　　Since the beginning of this year, Tianjin has made every effort to promote the cultural protection, inheritance and utilization of the Grand Canal, and carried out planning, cultural relics protection, project implementation, etc., and established a "1+4" planning system, namely, the Implementation Plan for Cultural Protection, Inheritance and Utilization of the Grand Canal in Tianjin and four special plans for cultural heritage protection, cultural tourism integration development, river water system management and protection, and ecological environment protection and restoration. The cultural protection, inheritance and utilization of the Grand Canal has changed from top-level design to full implementation stage.

　　Liang Jun, Deputy Director of Tianjin Development and Reform Commission:According to the protection of cultural relics, water resources protection and ecological restoration along the river, there are 9 categories and 51 key projects, with a total investment of 31 billion yuan. In the next step, Tianjin will adhere to one policy, pay attention to one map as a whole, highlight the protection of cultural relics, ecology, rivers, and accelerate the navigation of tourism in Beijing, Tianjin and Hebei.

　　Enjoy the charm of the canal by painting the ancient town in New Year.

　　The most distinctive section of the Grand Canal in Tianjin — — Xiqing section of the Grand Canal, where the Yangliuqing Grand Canal National Cultural Park has been started.

　　Headquarters reporter Wang Xiaopei:I am now located in the Xiqing section of the Grand Canal, with a total length of more than 30 kilometers, of which 16.5 kilometers is a world cultural heritage, and the ancient town of Yangliuqing is on both sides of the canal. Just now, I also experienced a circle by boat, and the scenery on both sides of the strait in the water is also unique. On the north side of the canal is the most prosperous amorous feelings block in Yangliuqing town, next to the Shijia Courtyard, a national 4A-level scenic spot known as the "first house in North China". On the south side of the canal is the Yangliuqing Grand Canal National Cultural Park, which was officially launched in 2019.

　　The Yangliuqing Grand Canal National Cultural Park covers an area of more than 2,800 mu, which is divided into three sections: a famous historical town, a treasure island and a cultural town. The core part is the treasure island, which is also the main part of planning and construction at this stage.

　　Yuanbaodao is divided into three areas: Jingu Wetland Cultural Tourism Zone, Chinese Traditional Quyi Cultural Experience Zone and Nian Cultural Experience Zone, as well as the vitality ring of water transport culture.

　　The entire Yangliuqing Grand Canal National Cultural Park, when planning, has three adherences.

　　First, insist on planning before moving. That is to solve the problem of "how to plan and what to build". In fact, before you see this planning version, there are five versions planned and designed by famous designers from all over the country and even the world. The final version can be said to be the most suitable for Yangliuqing, Tianjin and the Grand Canal.

　　The second is to adhere to cultural guidance and solve the problem of "how to protect and inherit what". The biggest charm of Yangliuqing Grand Canal National Cultural Park is the Millennium culture behind it. In addition to Yangliuqing New Year pictures, there are also a series of national non-legacy projects such as paper-cutting and kites. In the future, the China New Year Picture Museum will be planned and built here, giving full play to Yangliuqing’s New Year Picture culture, water transportation culture and rushing to camp culture. At the same time, according to the principle of "preserving the past, inheriting the past, promoting the past and using it", we will learn from the exhibition method of Riverside Scene at Qingming Festival to realize the reappearance of historical scenes. That is to say, the buildings repaired here will also show a bright breeze in the future.

　　The third is to adhere to the integration of cultural tourism and solve the problem of "how to operate and what to develop". For example, in view of the famous historical town plate, the method of "reactivation" is adopted to retain more than 800 existing old houses, to carry out historical and cultural restoration, to develop special tourism, special homestays and other formats, and to introduce market capital, focusing on building canal water street, intangible experience, Chinese time-honored brands and other formats, so as to turn this place into a tourist attraction and a cultural punching place.

　　Tianjin is a city born and prospered by rivers. Everyone in Tianjin has learned the warmth and perseverance of water, and also has the obligation and responsibility to protect, inherit and make good use of the Grand Canal and its long-standing culture. The designers and managers of the National Cultural Park also have a small wish, that is, to make people all over the world yearn for celebrating the China Year of the Lunar New Year in Yangliuqing, so that tourists from Beijing, Tianjin and Hebei can have a full moon weekend in Yangliuqing and enjoy the living heritage here.

　　Nowadays, the competition in China’s cosmetics market is fierce, and the domestic cosmetics market has been growing, and more and more emerging brands have emerged. However, in the era of fragmentation, if brands want to break out of the circle and get long-term development, they must have a keen insight into the trends in the industry and have a deep understanding of the needs of consumers. As a new generation of professional beauty brand, Perfect Diary has been making continuous efforts in the field of make-up skin for many years, leading the new beauty trend of makeup and maintenance, and bravely climbing the beauty peak.

　　In September last year, Perfect Diary once again waved the banner of innovation and successfully held the first launch conference of "bionic film" essence lipstick, which opened a new breakthrough in the integration of brand makeup and maintenance. This conference is a brand-new exploration of the definition of beauty, and it also brings more imagination space for exploring the combination of Industry-University-Research medicine and modern art aesthetics.

　　At the conference site, Perfect Diary also held the Biomimetic Membrane Technology Forum, and specially invited many experts such as Cheng Jing, chief scientific officer of Perfect Diary, to share and speak and witness the research and development story behind the new brand lipstick species, namely bionic membrane essence lipstick. Biomimetic film lipstick is the first product launched by Perfect Diary, which combines lip essence, blush makeup effect and lip film effect. The main purpose is to break through the limitations of traditional makeup products, and at the same time solve the problem of consumers’ demand for lipstick "color fixing and color locking", so that makeup products can also provide consumers with skin care effect and provide consumers with a brand-new product experience that truly conforms to the concept of "integrating makeup and nourishing".

　　Perfect diary bionic film essence lipstick through the creation of lip bionic film Biolip™ Technology, with biotechnology research and development to enhance product efficacy, create lip bionic sebum film, while achieving excellent effects of color development and uniform color locking, it can also dilute lip lines, increase skin moisture content after continuous use for two weeks, significantly improve lip dryness and roughness, and make lip skin smoother. In addition, Perfect Diary has made great innovation in formula research and development with the first bionic film essence lipstick, and also chose to return to simplicity and neatness in packaging design, which is closer to the needs of consumers. The perfect diary of the new era adheres to the research and development concept of BIO-TEC biotechnology products, integrates biotechnology and skin care ingredients, and leads the new trend of cosmetic care.

　　Perfect diary insists on taking consumers as the center of gravity and constantly improving brand strength. I hope that in the future, Perfect Diary will continue to challenge the boundaries of beauty cosmetics, and together with various forces inside and outside the industry, it will continue to lead the growth and progress of beauty cosmetics, promote the sustainable development of beauty cosmetics industry with practical actions, and create more effective cosmetic products.

　　"Extreme cold waves are more likely to break out."

　　After the "cliff-like" seasonal cooling during the National Day, a new round of cold air followed after the holiday, bringing strong winds, cooling and rain and snow to the central and eastern regions of China. According to the Central Meteorological Observatory, on the 10th, the impact of cold air was coming to an end. However, there were still moderate to heavy rains and local heavy rains in eastern Jilin and eastern Heilongjiang. There are sleet or small to medium snow in the northeastern part of Liaoning, the eastern mountainous area of Jilin and the southeastern mountainous area of Heilongjiang, and there are heavy snowstorms in the eastern mountainous area of Jilin.

　　Despite psychological preparation, the temperature drop in early October exceeded expectations, and some areas experienced record-breaking heat and cold overnight in winter. From blowing air conditioners to wearing long trousers, people can’t help wondering: Why did the cold wave come so early this year?

　　The temperature in many places in the south is "big diving"

　　On October 2, the Central Meteorological Observatory issued a blue warning of cold wave, which is the earliest cold wave warning issued in the second half of the year since the Central Meteorological Observatory officially launched the early warning release mechanism in 2010. From 14: 00 on October 2 to 20: 00 on October 6, the temperature in most parts of central and eastern China generally dropped by 8 ~ 12℃, and the temperature in central and eastern Inner Mongolia, Northeast China, most of Shaanxi, Huanghuai, Jiang and other places dropped by 12 ~ 16℃, and the local temperature dropped by more than 18℃.

　　When the cold wave in the north hit and the temperature dropped sharply, most areas in the south were still as hot as midsummer, and they were in the yellow warning of high temperature, with the local temperature reaching above 40℃. 470 national meteorological stations such as Hefei, Nanchang, Changsha and Hangzhou also broke the record of the highest temperature in October. It is understood that this is also the first time in history that two early warnings of high temperature and cold wave have been released at the same time.

　　When the cold air drives straight, the temperature in many places in the south "dives", and the temperature in some areas such as Anhui, Hubei and Jiangsu even drops by more than 20℃. First, it experienced the hottest in the same period in history, and then it experienced a "seasonal" cooling. Many netizens in the south said that it seemed to be a day from summer to winter.

　　After the National Day holiday, a new cold air continued to hit, which was accompanied by rain, snowfall and windy weather. From 8th to 10th, a new round of strong cold air will affect the central and eastern regions of China, and the lowest temperature in some northern regions will hit a new low since autumn. In addition to cooling, it also brings strong winds, rainfall and snowfall.

　　On the 10th, the impact of cold air came to an end, but there was still cooling and rain and snow in the northeast. On the 11th, the lowest temperature in Guangdong fell below 10℃, and the lowest temperature in most parts of the province hit a new low in the second half of the year.

　　This is a crisp autumn in October, and the cold air continues to exert its strength. Many places in China have "seasonal cooling". Why? Zhang Tao, chief forecaster of the Central Meteorological Observatory, analyzed that in the first half of the National Day holiday, the subtropical high was unusually strong and had a large influence range, and the highest temperature broke the historical extreme value in some parts of the north and south, showing a warmer trend on the whole. Under such circumstances, a strong cold air cut down from the low altitude of the subtropical high from north to south, the ground temperature dropped sharply, and the cold and warm air confronted each other, resulting in rainy weather along the Huaihe River, and the continuous rainy days led to the coldest day in the same period in history.

　　The recent frequent cold air activities will have an impact on the drought in the Yangtze River basin in China. Peng Jingbei, a senior engineer in lasg, analyzed that, on average, the precipitation in autumn in the Yangtze River basin is less than that in summer. Precipitation often occurs in areas where cold and warm air meet. When the cold and warm air forces are equal, it is easy to have continuous precipitation. However, since October, China has been hit by strong cold air one after another. On October 8-9, windy weather appeared in Beijing and other places, with gusts of 7-9 and local level of 10. Such a strong wind shows that the cold air is strong, and in this case, it is not easy to sustain heavy precipitation in the southern region. "In fact, on October 5-9, the temperature in the Yangtze River basin was more than 4 C lower than normal, but the meteorological drought in the Yangtze River and its south remained."

　　Will it be colder in winter?

　　After experiencing the latest high temperature warning and the earliest cold wave warning in history, many netizens are worried that autumn is already very cold, will it be colder this winter and will it experience extreme cold wave?

　　Earlier in September, the United Nations World Meteorological Organization (WMO) predicted that La Nina, which began in 2020, would last until the end of this year, which would be the first "triple" La Nina phenomenon in the 21st century.

　　In fact, as early as April-May this year, the Institute of Atmospheric Physics of Chinese Academy of Sciences used the scientific apparatus Earth System Simulator to predict that La Nina events will occur for three consecutive years in 2022-2023, and provided accurate prediction and early warning to relevant departments. In the spring and summer of 2022, the sea surface temperature in the tropical Middle East and Pacific Ocean has been in a relatively cold state all the year round, and the coldness has further intensified since autumn. The latest forecast results show that the current La Nina state will continue and develop in autumn and winter in 2022, reaching its peak in winter.

　　Will the influence of the new round of La Nina be greater than that of the past two rounds? Zheng Fei, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said that it is impossible to judge at present. On the one hand, there are few examples of La Nina events for three consecutive years in history, so it is impossible to give a statistical conclusion; On the other hand, the intensity of this La Nina event will be in the category of moderate intensity, and how to develop and influence China’s climate in the future still needs to be predicted continuously to enhance its credibility.

　　At the end of September, Xiao Chan, deputy director of the National Climate Center, said at the regular press conference of China Meteorological Bureau that under the background of global warming, the frequency of warm winters has increased since 1986. In the winter after La Nina incident, there were years when the temperature was low. The main characteristics of the abnormal temperature in winter were: the temperature in most parts of the country was lower than normal, especially in northern North China, southern Northeast China, most of southern China, eastern and northern Southwest China, and most of northwest China. After the La Nina incident, the winter precipitation in China mainly shows as follows: a large range of precipitation is less, especially in the eastern part of Northeast China, along the middle and lower reaches of the Yangtze River, in the southern part of Southwest China, and in northern Xinjiang. There is more precipitation in the northern part of southwest China and the eastern part of northwest China.

　　However, Xiao Chan also pointed out that La Nina event is only one of the external forcing factors that affect China’s winter climate. China’s winter climate is also affected by Arctic sea ice, Eurasian snow and other factors, and the natural variability within the atmospheric system also plays an important role. The Meteorological Bureau will strengthen the judgment and provide more detailed forecast opinions in late October.

　　Zheng Fei believes that under the synergistic influence of La Nina event and the warm Arctic Ocean, the cold air activity in China is likely to continue to be strong this winter, and it is prone to staged low temperature and extreme cold events. At present, based on the warm Arctic sea temperature in the previous period and the possibility of La Nina events in the future, it is predicted that the temperature in some parts of northern China will be slightly lower this winter, which may lead to staged low temperature due to the influence of staged cold air, and the possibility of extreme cold wave outbreak is high; In some parts of the south, there is the possibility of disasters such as low temperature, freezing, rain and snow, so we need to be vigilant and raise our awareness of prevention.

　　Luo Jingjia, a national distinguished professor of Nanjing University of Information Science and Technology, also said in an interview with Modern Express that for East Asia, the winter under the influence of La Nina will be colder. However, the emission of carbon dioxide is increasing, and the degree of coldness may not be so obvious compared with the previous La Ni? a event, which may not cause a very cold winter, but its cooling may be reflected by the occurrence of a cold wave phenomenon. "Therefore, we should pay special attention to the number and intensity of possible cold waves this winter."

　　Expert: Extreme cold events tend to increase.

　　In the past summer, there were rare high temperature and heat waves in all parts of the northern hemisphere. Most parts of China are also shrouded in high temperature, and high temperatures above 40 C continue to appear in many places. Global warming, why is there a strong cold wave?

　　Many experts said that there is no contradiction between strong cold wave and global warming. It is in the context of global warming that the climate is more unstable, with the frequency and intensity of extreme weather events such as rainstorm, high temperature heat wave, drought and flood in summer, extreme low temperature and cold wave in winter increasing. For example, from December 2020 to January 2021, China suffered from extreme cold waves one after another, resulting in large-scale cooling and extreme low temperatures in many places.

　　Zhao Liang, a senior engineer in lasg, told China Newsweek that from the statistics of frequency, in the past 20 years, the number of cold wave days in winter in China showed a downward trend as a whole, but there was a great difference in time and space. Spatially, the reduction of cold wave days mainly occurred in the south, but the number of cold wave days in the north, especially in the northeast, did not decrease. In time, the frequency of strong cold waves is more in the first half of winter, and the reduction of cold waves is mainly concentrated in the second half of winter (February).

　　It is worth noting that since 2008, the average minimum temperature of the coldest winter period in eastern China, that is, the strongest cold wave events every year, is lower than that in the 1980s and 1990s, that is to say, the strong cold wave events have an increasing trend.

　　Zhao Liang further analyzed that the change characteristics of cold events in China are closely related to the important changes of atmospheric circulation and polar system in the northern hemisphere caused by global warming. Among them, the warming of the Arctic in winter and the cooling of the mid-latitude continent — — That is to say, the warm Arctic-cold continent phenomenon is an important change pattern. This phenomenon has an important connection with the outbreak of extreme cold events in mid-latitudes, including China, especially aggravating the strong cooling events in northern China.

　　"With the persistence of global climate anomalies, it seems that the extreme cold (cold wave) event in the northern hemisphere in winter has been ‘ Home-cooked meals ’ . But there is great uncertainty about where and when it will happen, "said Yao Yao, an associate researcher at the Institute of Atmospheric Sciences. The continuous increase of greenhouse gases has made the earth warmer and warmer, and the atmosphere on which human beings depend has become increasingly unstable. For the northern hemisphere, polar vortex will become unstable more easily in winter. Under the guidance of favorable atmospheric circulation system, cold air will break through the westerly jet barrier more easily and frequently, and then be transported to middle and low latitudes, causing extremely cold (cold wave) weather.

　　For the early warning of extreme cold events, Zheng Fei stressed that short-term weather forecast and climate trend forecast for more than two weeks should be strengthened to improve the prevention and early warning of freezing rain and snow disasters. At the same time, agriculture, animal husbandry, energy and transportation industries need to pay close attention to the early warning of freezing rain and snow disasters and formulate effective preventive measures and emergency plans.
