When you browse the latest news of the Nobel Prize with your mobile terminal, do you think of the power supplier of your mobile terminal — — Lithium battery is the result of this year’s Nobel Prize!

　　On the afternoon of October 9th, Beijing time, the Royal Swedish Academy of Sciences announced that it would award the 2019 Nobel Prize in Chemistry to Professor John Goodenough, Professor Stanley Wittingham and Dr. Yoshinoya for their outstanding contributions in the field of lithium batteries.

　　How can lithium batteries, which are widely used in people’s daily lives, become Nobel Prize achievements? This has to start with the study of "batteries replacing oil".

　　In 1973, the fourth Middle East War caused the first oil crisis. The developed countries such as the United States realized the importance of getting rid of oil dependence and began to invest in battery research — — Battery can not only replace oil as a new energy source for automobiles, but also be an energy storage device for renewable energy such as solar energy and wind energy. Therefore, the enthusiasm of countries to develop this kind of battery is unprecedented.

　　The first breakthrough was Stanley Whitingham. He drafted the initial design scheme of lithium battery: titanium sulfide as cathode material and lithium metal as cathode material — — This proved to be a rechargeable battery. The energy density problem of battery materials, which has puzzled scientists for more than one hundred years, has also been solved by Wittingham one by one.

　　However, with the passage of time, it has been found that it is not safe to use metallic lithium as the negative electrode. The lithium battery will continuously precipitate dendrites with the increase of usage times, which will eventually cause the battery to spontaneously ignite.

　　Is there a solution to this problem? Professor Goodenough, who is 97 years old and the oldest winner in the history of the Nobel Prize, has made great contributions.

　　In 1980, Goodenough team proposed and found layered oxide cathode material — — Lithium cobalt oxide, which is still used in all kinds of mainstream consumer electronic products, and the negative electrode of lithium aluminum alloy, has brought mankind into the era of portable mobile phones and notebook computers.

　　In 1997, 75-year-old Goodenough and his team developed another more stable and safe cathode material, Ferrous lithium phosphate. It is the mainstream material for batteries used in electric vehicles, electric buses, electric ships, large-scale energy storage, communication base stations, data centers and so on.

　　Only a wider application can promote the further development of lithium batteries. How to integrate the experimental battery materials into usable devices and really apply them to small objects? Japanese scientist Akira Yoshino did it.

　　In 1990, after 10 years’ research, Akira Yoshino, then a researcher in a company, successfully used carbon instead of lithium alloy as the negative electrode of the battery. Combined with the lithium cobaltate positive electrode of Goodenough, this battery became safer and greatly reduced the risk of spontaneous combustion.

　　According to Yoshino Akira’s research, Sony officially launched the world’s first commercial lithium battery in 1991. Subsequently, they replaced the carbon cathode with graphene, which further improved the safety, energy density and cycle life of the battery.

　　Compared with lead-acid battery and nickel-silicon battery, lithium battery has the advantages of high energy density, long life and no memory effect, and is an excellent battery.

　　Back then, the invention of electric vehicles was much earlier than that of internal combustion engines. However, with the continuous improvement of internal combustion engine efficiency, the battery energy density is not high enough, which makes electric vehicles fade out. Now, electric vehicles have returned to people’s field of vision. An important premise is that lithium batteries, which were originally used to replace oil, have finally assumed an important historical mission.

　　At present, the global lithium battery industry is close to 50 billion dollars, and it is growing at a rate of more than 10% every year. Lithium battery has penetrated into all aspects of human life, and its invention has supported the continuous development of high technology in human society.

　　Obviously, lithium batteries have become the result of the Nobel Prize, and they deserve it!

Science and technology innovation board Journal, April 18th. While the global shipment of iPhone plummeted by nearly 10% in the first quarter, smart phone brands such as Samsung and Xiaomi began to increase the inventory of smart phones and OLEDs, which led to an increase in the operating rate of OLED production lines of panel suppliers such as BOE and Huaxing Optoelectronics.

According to South Korea’s The Elec today, citing industry sources,Smartphone companies such as Samsung Electronics, Xiaomi, OPPO, vivo and Huawei are all increasing the inventory of finished smartphones and OLED panels..

On the one hand, Samsung just replaced Apple in the first quarter and took the throne of "the world’s first mobile phone shipment". In the first quarter, it produced a total of 64.5 million smartphones and tablets, 22% more than the original planned 53 million; Among them, the sales volume of Galaxy S24 series in the first quarter was about 10% higher than that of the previous model, and the sales volume of ultra-low-priced model Galaxy A16 exceeded expectations.

On the other hand, because the sales of iPhone in China market are particularly low, China smart phone companies such as Xiaomi, OPPO, vivo and Huawei are looking for opportunities to occupy the iPhone market. An industry insider said, "Smartphone companies in China are oversubscribed.. "

The downstream mobile phone brand factory increased its inventory, and the orders of upstream OLED suppliers naturally rose.

Samsung shows that it has obtained a rigid OLED order for medium and low-priced mobile phones from Samsung Electronics, and the operating rate of related production lines has increased accordingly.. Samsung shows that it has sent a request to the equipment supplier, hoping to introduce relevant equipment to improve the panel performance.

China panel companies such as BOE, Huaxing Optoelectronics, Tianma, Visionox, etc. have also increased the operating rate of the sixth-generation flexible OLED production line. According to the news, some companies expect to fully put into production the 6th generation flexible OLED production line before the end of this year, and there is expected to be a large demand..

However, some insiders reminded that if the actual sales volume of related smartphones does not meet expectations in the future, the operating rate of OLED suppliers may decline.

　　Sino-US tariffs welcome new news.

　　Late at night on December 26th, Beijing time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Huawei successfully screened the screen today! On December 26th, the M9, the most expensive model of Huawei, went on the market, with a price of 469,800 yuan and a longest battery life of over 1,400 kilometers. Huawei Yu Chengdong said, "The M9 is the best SUV within 10 million yuan". He also said that the booking volume of M9 has exceeded 54,000. In addition, the poster released by Huawei on the evening of 26th showed that the two-hour listing of M9 (generally referring to reservation and no refund of deposit) exceeded 10,000 vehicles.

　　Look at the detailed report!

　　The Office of the United States Trade Representative announced that

　　On December 26th, local time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Prior to this, on September 6th, the Office of the US Trade Representative also announced that it would further extend the 301 tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, and the period would be extended from September 30th to December 31st this year. On September 7th, China’s Foreign Ministry spokesperson Mao Ning said that as a matter of principle, we have always opposed the fight against tariff war, thinking that there is no winner in tariff war. The unilateral imposition of tariffs by the United States on China violates WTO rules, which is unfavorable to China, the United States and the world.

　　According to previous media reports, during Trump’s administration, he invoked Section 301 (commonly known as Section 301 of the US Trade Act of 1974) in the name of "national security" to impose tariffs on China’s imported goods. During the Trump administration, there were more than 2,200 goods exempted from tariffs, of which 549 products were extended for one year, but all exemptions expired at the end of 2020. In October, 2021, the Office of the United States Trade Representative announced that it planned to re-exempt 549 imported goods from China, and solicited public opinions on this. After a lapse of nearly half a year, the Office of the US Trade Representative issued a statement on March 23, confirming 352 of the 549 imported goods from China that were to be exempted from tariffs again. This tariff exemption period has been extended many times so far.

　　In March 2022, Shu Jueting, spokesperson of the Ministry of Commerce, said at the press conference that China noticed that on March 23, the Office of the US Trade Representative announced that it would resume exempting 352 items of goods imported from China from additional tariffs, which would help the normal trade of related products. China has always believed that the unilateral tariff increase measures of the United States are unfavorable to China, the United States and the world. Under the current situation that inflation continues to rise and global economic recovery is facing challenges, it is hoped that the United States will cancel all tariffs on China as soon as possible from the fundamental interests of consumers and producers in China and the United States, and push bilateral economic and trade relations back to normal track as soon as possible.

　　The M9 in Wenjie is selling like hot cakes.

　　On December 26th, Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, officially released the M9 at the press conference of the world of inquiry and the whole scene of Huawei in winter, with the price starting from 469,800 yuan. Yu Chengdong said, "The M9 is the best SUV within 10 million yuan".

　　Wenjie M9 has launched four models with extended range and pure electric power, and the price range is 469,800 ~ 569,800 yuan, which is the most expensive model of Huawei at present. Among them, the extended range Max version is 469,800 yuan, the pure electric Max version is 509,800 yuan, the extended range Ultra version is 529,800 yuan, and the pure electric Ultra version is 569,800 yuan.

　　Yu Chengdong said that the order for the M9 has reached 54,000, and the first batch of new cars will be delivered on January 26th, 2024, and mass delivery will be started on February 26th. In addition, the poster released by Huawei on the evening of 26th showed that the two-hour listing of M9 (generally referring to reservation and no refund of deposit) exceeded 10,000 vehicles.

　　With the launch of new cars, there are three models under the brand of Wenjie: M5, M7 and M9. Together with the Zhijie S7, which cooperated with Chery not long ago, Huawei HarmonyOS Zhixing currently has two brands, namely Wenjie and Zhijie, and four models are on sale. In the future, Huawei will also work with BAIC andCooperate with new "Jie" generation brands and new models.

　　It is understood that intelligent car selection is the deepest cooperation mode between Huawei and automobile companies. Huawei not only provides key technologies such as intelligence, but also deeply participates in product definition and development, and also opens its own terminal channels to help sell cars. Previously, Huawei upgraded the smart car selection mode to HarmonyOS Zhixing.

　　It is the first partner of Huawei HarmonyOS Zhixing, and released the first intelligent car selection product in April 2021. In 2022, the sales volume of the brand series products created by both parties reached 75,000, which was once the fastest growing in China.Brand. However, in the first half of this year, the world encountered Waterloo, and the monthly sales volume once fell to more than 3,000 vehicles. Until three months ago, the listing of the new M7 in Wenjie achieved unexpected success, with orders exceeding 100,000 vehicles in just over two months. In order to deliver the model in time, the factory that produced the model invested more than 3,000 workers in two shifts, and delivered more than 10,000 single models in October and November for two consecutive months. Officials expect that the delivery of 23,000 vehicles will be completed in December, and the monthly delivery will exceed 30,000 vehicles next year.

　　He Liyang, president of Automobile Co., Ltd., said at the press conference on December 26th that Cyrus’ factory in Chongqing is stepping up production and has started the production mode of two shifts a day. He revealed that up to now, the number of new M7 cars in the world has exceeded 120,000, of which more than 60% users choose the smart driving version, and the monthly delivery capacity will reach 30,000 from January next year.

　　According to Blue Whale Financial News, it was learned from insiders close to Huawei that AITO will launch the new M5 in the first half of next year, and the brand-new M8 between M7 and M9 will also be launched in the second half of next year.

　　A-share "Huawei" want to be embarrassed again?

　　In the secondary market, this year,Concept stocks have been active repeatedly. Although they have been adjusted with the broader market recently, the Wind index still rose by more than 11% during the year, significantly outperforming the broader market index. In terms of individual stocks,The increase during the year exceeded 440%., Cyrus rose by more than 100%,、Wait for the increase to exceed 40%.

　　Recently, Huawei Technologies Co., Ltd. applied for registration of "Zunjie" and "Qingjie" trademarks, which are internationally classified as means of transport and scientific instruments, and the current trademark status is awaiting substantive examination. Previously, Huawei had applied for a series of trademarks related to the world, including Wen, Zhi, Yong, Hui, Zhu, Ao, Zhi and Yi. Not surprisingly, most of these "Jie" trademarks are prepared for HarmonyOS Zhixing Ecological Alliance. The above news once triggered a rise in concept stocks.

　　Recently, it was pointed out that Huawei vigorously laid out its automobile business, and the three models enabled automobile enterprises to build and sell good cars from simple to deep. Since 2023, the automobile business map has accelerated. Under the background of the rapid development of smart car industry, Huawei is expected to rise with the advantages of core technology, ecology, brand and channels. It is suggested to pay attention to the cooperative car enterprises in Huawei’s automobile industry chain and the core manufacturers in related fields such as intelligent driving, intelligent cockpit, three-electric system and traditional parts.

　　HuaxinIt is also indicated that the M9 is fully ahead in terms of safety, maneuverability and intelligence, and it is expected to become a new generation of explosive models, which will drive the flexibility of supply chain enterprises. It is suggested to focus on supply chain investment opportunities.He also said that he is optimistic about Huawei’s automobile industry chain.

　　Guosheng recently pointed out that the M9 in the world is expected to become another explosion of Huawei’s intelligent selection system, and it continues to verify that Huawei’s intelligent selection and empowerment car companies bring high growth. Continue to be optimistic about Huawei’s smart car industry chain. Smart car is a subdivision track with clear competition pattern and excellent medium-term logic. Considering Huawei’s industry-leading effects in autonomous driving, intelligent cockpit and intelligent safety, Huawei’s cooperative ecology is expected to enhance its product strength in the environment of intensified competition in the whole machine factory, and companies related to the industrial chain are expected to benefit from the development dividend of domestic smart cars by relying on ecological advantages, forming a pre-paid card position. At the same time, it is necessary to pay attention to the industrial changes brought by technology leaders, and autonomous driving is expected to accelerate its landing, forming an overall opportunity for the industry.

The P70 mobile phone was not released, but Huawei brought the "new" intellectual S7 and the first laptop MateBook X Pro equipped with Pangu model.

On April 11th, Huawei HarmonyOS Ecological Spring Communication Meeting was held online. Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, revealed the latest sales data of HarmonyOS Zhixing at the press conference. The number of new M7 was 174,000 in seven months, and the cumulative number exceeded 70,000 in three months.

Xinzhijie S7 launches Huawei Visual Intelligent Driving HUAWEI ADS Scheme.

Zhijie is a smart car jointly built by Huawei and Chery. This time, it’s a new intellectual S7 based on the old S7. There are five products in Zhijie S7 released by Huanxin this time, namely Zhijie S7 Pro, Zhijie S7 Max, Zhijie S7 Max+, Zhijie S7 Max RS and Zhijie S7 Ultra. The price starts at 249,800 yuan.

This time, Huawei launched the basic version of HUAWEI ADS, and Zhijie S7 Pro will be equipped with this pure vision solution for the first time.

There are two schemes of automatic driving: lidar and pure vision, and there has been a debate in the industry about the advantages and disadvantages of the two schemes. Huawei used lidar scheme before, and this time it launched a pure vision scheme.

According to Huawei, visual intelligent driving does not rely on lidar and high-precision maps, which can realize "quick and easy opening of national high-speed cities and easy stopping of intelligent parking". Yu Chengdong also said at the press conference that Huawei’s pure vision scheme is better than Tesla’s posture experience. Tesla mainly adopts visual driving scheme.

In terms of battery life and charging efficiency, Zhijie S7 is fully equipped with Huawei Whale 800V high-voltage battery platform, with a minimum power consumption of 12.4kWh per 100 kilometers and a longest cruising range of 855km.

In the field of intelligent cockpit, the Super Desktop 2.0 of HarmonyOS 4 system supports the full boarding of mobile phone applications, and HUAWEI MagLink can expand the screen for the back row. In addition, in-vehicle smart assistant Xiaoyi will be connected to Huawei Pangu model in May.

The old Zhijie S7 was released in November, 2023, positioning a smart car with high energy and large space, with four configurations, with a pre-sale price of 258,000 yuan. However, the sales volume after listing and delivery is not very ideal. At one time, there were network rumors that Chery did not actively cooperate with Huawei in the production of Zhijie S7, and only allocated a small amount of production capacity to Zhijie S7, with a daily output of only a few dozen vehicles, which led to a large number of orders that Zhijie S7 could not deliver. However, Jin Yibo, a spokesman for Chery, responded to the The Paper reporter that the online rumors were not true, the cooperation between the two sides was smooth, and the resignation of senior executives was not due to the cooperation project. According to public data, the cumulative sales volume of Zhijie S7 is 2,297 units in the three months since its listing.

However, Huawei has always been good at rejuvenating old cars. At the beginning, it asked the old M7 models to sell well after rejuvenation. Can the new intellectual S7 replicate the brilliance of the new intellectual M7?

Chery has also made improvements in response to the delivery problem that was previously spit out. Yin Tongyue, Chairman of Chery Group, said at the communication meeting that Zhijie is Chery’s first priority strategic project, and an independent brand division has been established, led by the person in charge of R&D and manufacturing. The intellectual community has an exclusive manufacturing industrial park and special resources investment guarantee. Yu Chengdong said that Zhijie S7 got off the assembly line one car a minute, and now it has started mass delivery.

In addition, the price of Xinzhijie S7 has also been adjusted to make it more competitive. The latest consumer who buys Zhijie S7 will enjoy the rejuvenation rights worth 30,000 yuan, and the old owner will enjoy the owner care worth 13,000 yuan, including 10,000 yuan of cash-filled red envelopes. After this operation, Xinzhijie S7 and Xiaomi SU7 collided head-on in price.

Of course, we will often do what we are good at, and then Huawei will issue an upgraded M5. Yu Chengdong revealed that the new M5 will be released on April 23rd, 2024.

Huawei MateBook X Pro released, equipped with Pangu model.

Huawei also released Huawei MateBook X Pro, the first notebook computer equipped with Pangu model. This 14-inch notebook computer takes a thin route and weighs only 980 grams, but with the blessing of a large model, it can be more intelligent.

According to reports, the first application of Huawei Pangu model, AI summary function can quickly and accurately extract key information from text, audio and video content, which can help users quickly and accurately filter out valuable content from massive information, thus helping users to master the main points of the meeting more efficiently.

Huawei MateBook X Pro is also equipped with Huawei’s AI space function for the first time. Through the AI space, users can directly access rich AI applications with one click, and support more than 100+ agents. It is a one-stop AI capability aggregation portal, which can make code programming, PPT production, paper reading and typesetting, collection of learning materials, video picture creation, travel planning and other scenes more efficient and convenient.

In addition, the star flash version of Huawei wireless mouse was released together with Huawei MateBook X Pro.

Compared with the previous generation of Huawei wireless mouse, the anti-interference ability is improved by 4 times+,and the complex environment is more stable. Huawei MateBook X Pro’s new products start at 11199 yuan.

　　Zhongxin Jingwei Client May 23rd (Zhang Yunan) CPI data of 31 provinces in April 2019 have been released one after another, and hot topics such as "Garlic You Bite", "Cherry Freedom" and "Toona sinensis Freedom" have recently returned to the public’s field of vision. Under the strong siege of vegetable prices and fruit prices, what are the CPI performances of the provinces?

　　CPI in 16 provinces rose more than the whole country.

　　In April 2019, the national consumer price rose by 2.5% year-on-year, continuing to be in the "2 era". In food, the price of fresh vegetables is still at a high level, rising by 17.4% year-on-year, affecting the CPI increase by about 0.43%; Pork prices rose by 14.4%, an increase of 9.3% over the previous month, which affected the CPI increase by about 0.31%. Last autumn, the fruit harvest in the north was poor, and this year’s stock was insufficient. The price of fresh fruit rose by 11.9%, which affected the CPI increase by about 0.22%.

　　From the perspective of 31 provinces in China, according to the incomplete statistics of Sino-Singapore Jingwei client, the CPI of 16 provinces rose more than the whole country in April, with the highest increase in Tianjin, Hebei and Anhui, reaching 2.9%; Hunan and the national CPI rose flat, up 2.5% year-on-year; The increase in Beijing and Xinjiang was small, at 1.6%.

　　Don’t look at the classification, there are 13 provinces with a year-on-year increase in fresh fruits over the whole country, and Anhui has an increase of 30.9%, the largest increase; Only the fresh fruit in Ningxia rose by more than 20%, which was 20.4%; There are 18 provinces with an increase of over 10%, with a large number; Qinghai rose by 1.9%, with a small range.

　　In addition, there are 10 provinces where the year-on-year increase of fresh vegetables exceeds the national level; Chongqing and the national fresh vegetables rose at the same level, at 17.4%; There are three provinces with an increase of less than 10%.

　　On pork, from the provinces that have announced the increase, Anhui has the largest increase, reaching 24.7%; Followed by Sichuan, up 23.4%; The lowest is Guizhou, up 7.6%.

　　Is it really so difficult to achieve "fruit freedom"?

　　Following "Toona sinensis Freedom", "Garlic You Are Malicious" and "Cherry Freedom", "Fruit Freedom" has also been screened on the Internet recently, which has aroused heated discussions. In fact, after the Spring Festival, the news about the price increase of fruits is endless. It is even reported that the fruit price in Beijing Xinfadi wholesale market has generally increased by 78% compared with the same period of last year.

　　The Zhongxin Jingwei client combed the website data of the Ministry of Agriculture and Rural Affairs and found that the price of Fuji apple has been rising for 9 weeks in a row among the five fruits it focuses on monitoring. As of mid-May, the price of Fuji apple was 10.33 yuan/kg, up 60.7% year-on-year. In addition, the price of watermelon has been on the rise year-on-year. As of mid-May, the price of watermelon was 4.86 yuan/kg, up 29.7% year-on-year.

　　It is worth noting that the retail price of fruit is also "rising". According to the data of Hunan Provincial Department of Commerce, from May 15th to 21st, the number of seasonal fruits on the market decreased, the purchase price of producing areas increased, and the average retail price of fruits increased. The retail prices of six kinds of fruits monitored mainly increased by 3 and decreased by 3, and the overall average retail price increased by 0.28% from the previous month. Among them, the prices of grapes, apples and pears rose by 1.01%, 0.52% and 0.2% respectively.

　　According to the data of Zhejiang Provincial Department of Commerce, from May 6 to 12, the purchase and sale of the market dropped in the week after May 1, and the overall price rose slightly, with the price of fruits and eggs rising at the top. The wholesale market price of fruit rose by 1.7%, and the supermarket price rose by 3.7%. At present, there are many kinds of fruits in the market. The average price of cherries, loquats, cantaloupes and watermelons in other producing areas has increased due to the stacking of transportation costs in other places, low early adopters and high prices.

　　Is "fruit freedom" really hard to achieve? In response, Liu Aihua, spokesperson of the National Bureau of Statistics, responded on May 15th that the prices of fresh vegetables and fresh fruits are obviously affected by seasonal factors of extreme weather, and these seasonal short-term shocks are not sustainable, so the price increase of fresh vegetables and fresh fruits will not last at a high level.

　　Haitong futures also analyzed that the recent increase in fruit prices was attributed to the severe weather in the north and south fruit producing areas in 2018-2019. Therefore, in the gap period of the current fruit market, the summer melon fruits with large output have not been listed yet, the fruit stocks in the north have basically bottomed out last year, and the tropical fruits in the south are expected to reduce production. Under the influence of multiple factors, the fruit market price has been rising.

　　As for the worry that the "cherry freedom" of the screen is difficult to achieve and the ordinary "fruit freedom" is lost, some institutions think it is unnecessary anxiety. The price of fruit is determined by market supply and demand, and the price increase is a short-term phenomenon. With the adjustment of the market, the tide of fruit price increase may end.

　　Haitong futures said that in the short term, after June, summer fruits will be listed in large quantities. Although the production of litchi, longan and mango in the southern tropical fruit producing areas is expected to decrease, the output of mainstream fruits such as watermelon, cantaloupe and peach is expected to maintain the normal level in previous years, while the output of bananas and oranges is expected to increase slightly. Therefore, the overall supply of summer fruits is sufficient, and "fruit freedom" can still be expected.

　　CITIC Jiantou also analyzed that from the historical market, after experiencing a short-term price increase in the second quarter, fruit will gradually fall back and remain in a relatively stable range. This is mainly due to the production pressure caused by the interference of weather factors. After the price increase in the second quarter, it will be released, and the listing of new fruits in the later period will further stabilize the price. Therefore, fruit prices do not have the conditions for a sharp rise, but there will be a wave of rising prices in the short term.

　　Regarding the trend of CPI in the second quarter, Liu Aihua pointed out that there will be no sharp increase in CPI in the future, regardless of food, industrial consumer goods and services, and there is a solid foundation for stable prices. Everbright Securities believes that the year-on-year increase of CPI is expected to reach a high of 2.6% to 2.7% in the second quarter and this year, respectively, and the annual center may be 2.3%, the highest level in the past five years.

Since the evening before yesterday, the temperature in Hangzhou has turned straight down.

At 15 o’clock the day before yesterday, the temperature in Hangzhou was 26.1℃, and at 23 o’clock in the evening, the temperature was only 12.2℃. In just 8 hours, the temperature dropped by nearly 14℃. Yesterday, the lowest temperature in Hangzhou was 11℃. The temperature in the whole day seemed to have no heartbeat, and there was almost no fluctuation. By 14 o’clock, the temperature in Hangzhou was only 11.4℃.

Just when Hangzhou people "spit" spring is like the four seasons, many friends said:Not only is the four seasons in Hangzhou chaotic, but it snows heavily in Henan!

With the cold air heading south, rain and snow occurred in parts of Henan, Shanxi, Shaanxi, Hubei and other places from yesterday morning to morning, and snowfall mainly occurred in southeastern Shaanxi, southwestern Shanxi and western Henan.

Yesterday morning, heavy snow fell in Luoyang, Henan Province, and "Snow in Henan" once rushed to the top of the hot search. In the afternoon, snowflakes floated in Zhengzhou, the provincial capital.

Yesterday morning to afternoon, the snowfall (turning into water) in Luanchuan, western Henan Province has exceeded 20 mm, reaching the level of heavy snowstorm. The local meteorological observatory has issued a yellow warning signal of snowstorm red warning signal and road icing. The snow is as thick as a quilt, and it is 18 cm at 14: 00, which is rare in March. The local snow record in March is 20 cm (March-April, 1992).

On March 16, many places in Henan ushered in snowfall, with moderate to heavy snow and partial blizzard in some areas. As of 15: 00, Lushi County, Songxian County, Ruzhou City, lingbao city City and Dengfeng City in Henan Province have issued red warnings for snowstorms. The reporter learned from the Henan Meteorological Bureau that this round of snowfall was mainly caused by low-level southward cold air and strong southerly warm and humid airflow.

Due to the rapid warming in the early stage, the current Henan is full of red flowers, green willows and green spring colors. And the arrival of this round of rain and snow cooling weather, press the "deceleration button" for spring warming. In Zhengzhou, the provincial capital, the rainfall that began to appear on the morning of the 16th gradually increased. In the afternoon, the sky was covered with patches of snow, and the temperature was also lower, and the chill burst. In Luoyang, Sanmenxia and other places, heavy snow fell from the sky and soon covered the earth with "white clothes".

According to the analysis of meteorologists from Henan Meteorological Bureau, this round of snowfall in Henan is mainly caused by the low-level southerly cold air and the strong southerly warm and humid airflow. On the 15th, the cold air southward caused a sudden drop in temperature, forming a cold air cushion near the ground. The abundant water vapor carried by the warm and humid airflow with strong southerly direction quickly climbed on the cold cushion, condensed or condensed, and then landed on the ground, forming the snowfall in Henan. In addition, the temperature in the western mountainous area of Henan province is lower, and the snowfall occurs earlier. The precipitation phase in the central area will gradually change from rain to sleet or snow with the further decrease of temperature.

According to the monitoring of Henan Meteorological Observatory, at 7: 00 to 11: 00 on March 16th, moderate rain and snow occurred in some counties and cities in Sanmenxia, Luoyang, Jiaozuo and Nanyang, and local snowstorms occurred. The top three snowfalls are Xin ‘an 19 mm, Lushi 10.3 mm and Luanchuan 9.6 mm respectively.

The Henan Meteorological Observatory predicts that there will be heavy precipitation from the afternoon of the 16th to the first half of the night, and some counties and cities such as Luoyang, Zhengzhou, Pingdingshan and Nanyang will have moderate to heavy snow and local snowstorms. Xinyang is rainy with lightning. After midnight, the precipitation gradually weakened and moved out of Henan Province.

The Henan Meteorological Observatory issued a blue warning of blizzard at 11: 00 on the same day: It is estimated that there will be more than 5 mm of snowfall in Sanmenxia, Luoyang, Pingdingshan, central and northern Nanyang, Zhengzhou, western Xuchang, Jiyuan, western Jiaozuo, western Xinxiang and western Anyang during the day and night, including more than 10 mm of snowfall in Sanmenxia, Luoyang, western Zhengzhou, western Pingdingshan and northern Nanyang. At 9: 30 on the same day, the Henan Meteorological Observatory also issued a yellow warning for road icing.

Snow in March is also called "Peach Blossom Snow"When the peach blossoms are in full bloom, the wind blows the petals like snow, and later people call the snowflakes falling with the peach blossoms peach blossom snow.

You know, a week ago, Zhengzhou experienced the "summer" in advance, and the highest temperature exceeded 30℃. A week later, it began to "peach blossom snow" in March, which was really a random crossing of the four seasons.

In addition, from the weather phenomenon and lightning monitoring, some parts of Henan province have been thundered and snowed.

Many netizens feel quite puzzled.It’s March, and it snows at this time, and it can also thunder and snow. Is it abnormal?

According to the analysis of China Weather Network,At this time, it is in the season of alternating cold and warm, and it is normal to snow. In previous years, it snowed in April.Snowfall is mainly caused by the combined influence of warm and humid airflow in the south and the cold air infiltrating from the lower level to the south, and some areas are also caused by topography. For example, in mountainous areas with higher altitude, the temperature is lower, which is prone to snowfall.

As the cold air moves south, rain and snow will also change in some areas, and the snowfall area will spread further south. For example, in Mianchi, Henan Province, it rained from about 5 am yesterday, and it snowed from around 6 am to 10 am. The accumulated snowfall has reached 9 mm.

The phenomenon of "thunder and snow" has also happened in many places.When it snows, because the strong warm and humid airflow meets the strong cold air, the warm and humid air is forced to rise, resulting in strong convection, which creates conditions for the formation of lightning, and the phenomenon of "thunder hitting snow" appears.

Some people say, "It snows in have no martial ethics only after the flowers bloom", while others care.: I wonder if crops will have an impact?

Henan Meteorology said that due to the lack of precipitation in Henan Province in the early stage, the proportion of 0 ~ 10 cm short of moisture monitoring stations reached 55% (note: moisture is an important monitoring indicator of drought, mainly reflecting the situation of soil water content), and the forest fire risk rating was also high.This rain and snow process is very beneficial to improving soil moisture, ensuring wheat growth and reducing forest fire danger.It is expected that the rain and snow will gradually stop in most areas in the latter half of the night, but the cold in spring is still there. In the morning after tomorrow, the temperature in Henan Province is mostly around 0-5℃, and there are many fogs at the same time.
