Tell everyone a "cold" news, the strongest cold wave since the winter of this year is coming soon! It is predicted that from November 26th to 30th, the cold wave will sweep across China, and the temperature will plummet in most areas.

　　Speaking of the cold wave, many people have memories dominated by it. As the "strongest" cold air, how "cold" is the cold wave? What is the strongest cold wave in history? The reporter interviewed Ye Dianxiu, a senior engineer under research at the National Climate Center and the chief expert of meteorological services at the China Meteorological Bureau, and asked him once and for all.

　　1. What is the standard of cold wave? Is there a difference between the north and the south of China?

　　Cold wave is a kind of cold air and a kind of disastrous weather. According to the national standard of cold air grade in China (GB/T 20484-2017) formulated in 2017, the cold air activity that makes the daily minimum temperature in a certain place lower than or equal to 8℃ within 24 hours, or lower than or equal to 10℃ within 48 hours, or lower than or equal to 12℃ within 72 hours is called cold wave.

　　2. How strong is the "ability" of cold wave cooling?

　　Monitoring shows that the average cooling rate of each cold wave in most parts of China is above 10℃. The average cold wave cooling rate in most parts of Northeast China, Jianghuai, eastern Jianghan, Jiangnan and southern China, as well as most parts of Inner Mongolia and northern Xinjiang can reach 12.℃To 14℃, more than 14℃ in most areas of Guangdong and Guangxi.

　　The maximum cooling range of cold waves in Northeast China, most of North China, most of Northwest China, most of Huanghuai, most of Jianghuai, southern Jiangnan and most of Inner Mongolia and Tibet is above 20℃. Among them, the maximum cooling rate in most parts of Northeast China and Inner Mongolia, northern Xinjiang, northwestern Tibet and southwestern Qinghai can reach 25.℃To 30℃, more than 30℃ in some areas; The maximum cooling range of cold wave in Sichuan basin, most of Yunnan and Hainan is below 15℃, and that in other parts of the country is generally below 15℃℃To 20℃.

　　3. How many cold waves occur on average every year in China?

　　In China, cold waves mostly occur in late autumn, winter and early spring. In the past 30 years (1991-2020), cold waves have occurred 5.4 times a year on average in China.

　　Since 1991, the most frequent cold wave occurred in 2021, with 11 times. Followed by 2009, there were 8 times, and the least number of cold waves was in 2017, only 2 times.

　　4. Where did the cold wave affect our country come from?

　　The cold air affecting China can be roughly divided into the following four paths:

　　① Northwest route: Cold air enters China from the White Sea and Barents Sea west of Xindi Island via Siberia and Mongolia in the west.

　　② Northern route: Cold air enters northern Asia from Kara Sea or Novosibirsk Sea east of Xindi Island, and enters China from north to south via Mongolia.

　　③ Western route: Cold air affects eastern China from west to east in Eurasia south of 50 degrees north latitude via Xinjiang.

　　④ Northeast route: Cold air from the Sea of Okhotsk or eastern Siberia affects the northeast of China.

　　more thanPath,The first three paths are more common, while the last path is less frequent and less intense.

　　5. What are the cold waves with large temperature drop in history?

　　According to the monitoring results of cold air process, since 1991, the top five cold waves with comprehensive cold air intensity in China have appeared on November 4-9, 2021, March 11-14, 2006, March 18-22, 1998, February 14-17, 2020 and April 11-17, 2006.

　　Cold waves often bring a wide range of severe cooling, strong winds and snowfall. Taking the cold wave process from November 4 to 9, 2021 as an example, the land area with the temperature drop exceeding 8℃ is 7.709 million square kilometers, accounting for about 80.3% of the national land area. Among them, there are 1.011 million square kilometers whose temperature drop exceeds 16℃.

　　The daily minimum temperature of 172 national meteorological stations in Xinjiang, Gansu, Qinghai, Ningxia, Shaanxi, Shanxi and other places reached or exceeded the historical extreme value in early November.

　　The daily precipitation of 151 national weather stations in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Tianjin, Shanxi, Shandong and other places exceeded the historical extreme in November. There is obvious snow in many places in the north, and the depth of snow in Inner Mongolia, Jilin and Liaoning is more than 40 cm.

　　6. Where is the place most favored by the cold wave in China?

　　In China, the frequency of cold wave is characterized by more in the north and less in the south. The areas most favored by cold waves include: Northeast China, western and northern parts of North China, northern and central parts of Northwest China, most of Tibet, Inner Mongolia and other places, with an average annual cold wave frequency of more than 4 times. Among them, there are generally 10 to 15 times in the eastern and northern parts of Northeast China, most of Inner Mongolia and parts of northern Xinjiang, and there are more than 15 times in some areas.

　　7. In cold winter, are there more cold waves than in warm winter?

　　The answer is no.

　　There are obvious differences in judging factors and time periods between cold winter and cold wave, and the annual cumulative cold wave frequency is not necessarily related to cold and warm winter. Cold winter is a kind of climate concept based on the temperature condition of the whole winter, and the basic element of judging cold and warm winter is the average temperature of winter (December to February) for three months. The basic factors to judge the cold wave process are the daily minimum temperature (≤4℃) and the 24-hour (or 48-hour, 72-hour) cooling range (≥8℃, 10℃ or 12℃).

　　Therefore, the number of cold waves in cold winter is not necessarily more than that in warm winter. For example, both 1998 and 2019 were strong warm winters, and the number of cold waves was 6, which was more than that of strong cold winters in 1983 (3 times), 1984 (2 times) and 1985 (2 times).

The first taxi was introduced in 1980

Although the number of private cars is increasing, taxis are still an important means of public transportation in the city. Taxi passenger transportation in Xiangyang began in 1980.

It is understood that that year, Xiangyang City Rental and Public Car Company purchased two Fiat cars for taxi passenger transportation, mainly operating chartered business.

Three years later, the number of taxis in the urban area increased to six. By 1989, the municipal government allowed state-owned, collective and individual taxis to operate in accordance with the development of the national economy. The number of taxis soared to 48, 68 in 1992 and 90 in 1993. However, at this time, the operation mode of taxis was mainly to wait for passengers and charter passengers, and still did not go to the road to pick up passengers.

In 1995, urban taxis were uniformly installed with meters, and began to carry passengers on the road, charging according to the mileage displayed by the meters.

new visit

It has undergone seven major changes

From owning the first taxi to 2018, our city’s taxi market has undergone seven major transformations.

In 1996, Xiangyang City began to implement macro-control on the total number of taxis in the urban area, and implemented the paid use of taxi management rights. In that year, taxis were uniformly replaced with "T" license plates and installed taxi headlights. In 2001, the "T" license plate number segment for urban taxis was uniformly replaced with the "X" license plate segment. There are more than ten types of taxi models such as Alto, Van, and Fukang, and the freight rates are also different.

In 2003, after the original Xiangyang County was removed from the county and set up as a district, the Xiangyang Municipal Government brought the taxis in the original Xiangyang District into the unified management of Xiangyang City. With the approval of the provincial government, Xiangyang City increased the number of taxis by 180, bringing the total to 1,700. In the same year, the municipal government decided to phase out the taxis in three years and replace them all with Fukang cars. On July 6, 2005, the last yellow-faced taxis in Xiangyang City were withdrawn from the market, and all urban taxis were Fukang models. Since August 2008, urban taxis have been gradually replaced by Elysee models.

Since 2006, in response to the impact of rising oil prices on the taxi industry, the Municipal Passenger Management Office has negotiated with the public security vehicle management, price, technical supervision and other departments, and decided to convert the fuel to gas for taxis in the city. In December 2007, the oil-to-gas conversion of taxis in Xiangyang City was completed.

In July 2013, the municipal party committee and municipal government licensed the operation rights of 500 new taxis to the municipal public transportation company, pioneering a new road of "zero docking, zero contracting, zero shift fee, and zero part money" and "public bus" in the country.

In July 2016, according to the "Guiding Opinions of the General Office of the State Council on Deepening Reform and Promoting the Healthy Development of the Taxi Industry", the city started to deepen the reform of the taxi industry. In August of the same year, urban taxis stopped collecting paid transfer fees for operating rights, and cruise taxis officially entered the stage of free use of operating rights. At the same time, the legalization of online car-hailing was quickly started. After a year of preparation, the detailed rules for the implementation of online car-hailing have been revised more than ten times and were officially announced and implemented on December 7, 2017.

On January 26, 2018, our city issued the first online car-booking business license. On March 20, 2018, the first legal online car-hailing car officially went into operation. On September 25, 2018, Xiangyang’s local online car-hailing platform "Xiangyang Travel" APP was officially launched, and Xiangyang’s taxi industry officially entered the era of "cruise + online appointment".

In October 2018, the municipal transportation department integrated the original 23 intensive management companies into three modern cruise car companies with a certain scale, further clarifying the ownership of vehicle property rights, operating rights, and company intensive management rights, and resolving industry contradictions.

Outlook

"Internet + transportation" will bring more convenience

Taxi cars have been available in our city for 39 years.

Over the past 39 years, the urban taxi industry has continued to develop through reform. Today, there are 2,200 urban cruise taxis, 4 cruise taxi companies, about 5,000 employees, a daily operating mileage of 400 kilometers for bicycles, a daily operating income of about 600 yuan, and a daily passenger volume of about 200,000. There are 15 online ride-hailing platform companies, 688 online ride-hailing cars, and nearly 6,000 drivers have applied for online ride-hailing driver licenses.

With the deepening of reform, the operating environment of taxis will continue to improve. The rapid development of "Internet + transportation" will bring more convenience to citizens’ travel.

Witnesses say

Continuously enhance the citizen’s ride experience

In December 1989, at the age of 19, Yang Yongjun joined the Municipal Passenger Transport Management Office, which was established that year, and has been a law enforcement officer for 30 years. "There were only eight people in the entire Passenger Transport Management Office at that time. Now, there are more than 30 people in our three management offices alone," Yang Yongjun said.

Yang Yongjun introduced that Xiangyang’s first taxi company was Oriental Pearl Taxi Company, which was affiliated to the Oriental Chemical Plant and had 10 Alto; after that, Hubei Chemical Fiber Taxi Company and Light Boat Taxi Company entered the taxi market; later, Auto Trade Taxi Company appeared, and the yellow face entered the lives of Xiangyang people. "In the past, we mainly cracked down on illegal operation activities, but now we mainly regulate the business behavior of licensed taxis." Yang Yongjun said that with the development of society, people have more choices when traveling. As a passenger transportation management department, we must ensure that citizens who travel by taxi have a more comfortable and comfortable riding environment, and constantly improve the public’s riding experience.

　　[New Car Listed in car home] On May 18th, Chery Automobile’s (|) family was officially listed.The new car has launched a total of 9 models.Fuel version modelThe price range is 126,900-171,900 yuan.The new car is young and dynamic in appearance and richer in configuration. There will be 5-seat and 7-seat space layouts and 1.6T and 2.0T engines to choose from. See the table below for detailed models:

★ New car features

　　Externally, the new car only adopts a large-size front air intake grille, and is equipped with a dot-matrix mesh structure. The headlight groups on both sides are integrated with the front grille and connected by a chrome-plated decorative strip to form a through design. The front sides of the new car are also surrounded by polygonal heat dissipation openings, and the interior is equipped with horizontal LED daytime running lights.

　　On the side of the car body, the new car adopts the standard SUV body structure. The front and rear fenders protrude slightly from the car body, and the whole side lines are relatively flat. Together with the chrome-plated decorative strips under the car door and the large-size rims with dense spokes, it shows the fashionable and dynamic side of the car. In terms of body size, the length, width and height of the new car are 4745/1860/1745mm and the wheelbase is 2710mm respectively.

　　On the tail side, the new car is equipped with a roof spoiler, and the taillights adopt a through design, and the array shape of the internal light group is highly recognizable after lighting. In addition, the new car also adopts the exhaust design of four outlets on both sides, and surrounds the rear diffuser decorative panel in the middle after cooperation, so as to further enhance the dynamic effect of the vehicle.

　　In the interior part, the design style of the overall center console of the new car refers to the previous design idea of Chery OMODA 5, and the double screen design with a size of 24.6 inches is particularly eye-catching. The new car is also equipped with the W-HUD head-up display function developed by Chery, which can display the speed, dynamic ADAS, navigation, telephone and other forms, and can also make the user’s line of sight more focused, which is conducive to safe driving. In addition, the Tiggo 8 PRO is also equipped with SONY luxury 10-speaker surround sound, as well as a full-fledged atmosphere light group.

　　In terms of space, as a seven-seat model, the performance of the interior space of the Tiggo 8 PRO car is acceptable, and the design of hollowing out the back of the front seat gives more room for the second row of legs, which better ensures the seating space of the third row of passengers, and the performance of storage space is more conventional.

　　In terms of power, the new car will be equipped with a pure fuel vehicle with a 1.6TGDI/2.0TGDI engine and the latest Chery Kunpeng DHT hybrid system. Among them, the 1.6T turbocharged engine has a maximum power of 197 HP and a maximum torque of 290 Nm. The maximum power of the 2.0T engine is 254 HP and the maximum torque is 390 Nm. Both power versions are matched with a 7-speed dual-clutch gearbox and a four-wheel drive system is available.

　　In the future, the new car will also be equipped with Chery Kunpeng DHT hybrid system, which will provide "3 engines, 3 gears, 9 modes and 11 speeds" with "CHERY AWD" Chery all-scene intelligent control four-wheel drive system, so that the new car has six all-scene road modes including economy, ordinary, sports, camping, skiing and cross-country.

★　Test drive review

　　Previously, we have tested the 2.0T model version (the test-drive version, and the test drive experience does not represent the final production version). The engine parameters of this model are 254 HP and 390 Nm, which are in line with the 2.0T high-power engine of the first-tier manufacturers, but there are still some gaps in the actual experience. Mainly reflected in the power output process is not linear enough, and the low torsion performance below 2000rpm is weak. In addition, the stroke of the accelerator pedal is relatively long, and there is still a little empty position in the initial stage, which leads to the need for more accurate control of the ankle when following the car at low speed, otherwise the power will suddenly break out after the speed exceeds 2000rpm, and it is easy to go forward.

　　But if you are the kind of driving style that you must rush out first, then the performance of this engine will definitely satisfy you, skip the initial fatigue and go straight to the power sweet zone, and this momentum can continue until 5000rpm. Even if the cruise state suddenly accelerates, it can be done in one go, don’t believe you look at the test results.

　　For dual-clutch gearboxes, the attitude of China brand is mostly to keep comfort and abandon shift speed, and Tiggo 8 PRO is no exception. According to the standard of a family car, its performance is qualified, and the selection of gears and the switching between gears during stop-and-go can be smooth and natural, without any obvious frustration and hesitation. It’s just that in the face of sudden high power request, the speed of downshifting is not fast, and it’s not decisive enough. It can’t be lowered to the right gear at once, and sometimes it needs to be replenished.

　　The chassis does not adequately filter small bumps, and it is also sensitive to the feedback of road information, and there will be redundant jumping when passing through potholes and speed bumps. But if you insist, it doesn’t count. After all, there is no strong impact transmitted to the car. The long-stroke suspension is not well restrained when facing the roll, and the response of the car body is also lagging behind. Generally speaking, it is comfort and movement, and both sides are not in place, giving people a very general sense of texture and advanced feeling.

　　In general, the driving texture of the Tiggo 8 PRO is not as young as it looks, coupled with the high sitting posture and fuzzy steering wheel directivity, it still has a strong sense of "middle age". According to the data released by the manufacturers, the proportion of owners of Tiggo 8 over 36 years old is 56%, and that of Tiggo 8 PLUS is 40%. The main car buyers of Tiggo 8 PRO in the future will definitely be middle-aged, so this driving experience is in line with their car demand.

★ Model history

Tiggo 8 Kunpeng Edition

Tiggo 8 PLUS』

Tiggo 8 PRO』

　　The Tiggo 8 PRO is the third model of the Tiggo 8 family. At present, it is consistent with the two brothers in the series in terms of three major parts and body size, but it has changed its appearance, interior and configuration. Compared with Tiggo 8, which focuses on economy and practicality, Tiggo 8 PLUS focuses on luxury, while Tiggo 8 PRO focuses on youth and technology. It is aimed at the post-90 s family, which not only inherits the advantages of the large space of Tiggo 8 series to meet household needs, but also meets the needs of intelligent networking and young design after 90 s.

★ competitors

"Changan CS75 PLUS』"

　　As an SUV with a wheelbase of 2710mm and a price range of 150,000, Tiggo 8 PRO will continue to compete with its old rivals such as Changan CS75 PLUS, Haval H6 and Bo Yue X. While the Tiggo 8 family is constantly updating, competing products are also constantly innovating. For example, at the end of February this year, the new CS75Pulse, a powerful competitor in this market, ushered in the market. In terms of paper strength, Tiggo 8 PRO has a good technology and automatic driving assistance configuration compared with competing products. At the same time, Tiggo 8 PRO will launch a hybrid model in the future, and it has taken a leading step in power selection compared with competing products. I hope its appearance will contribute to the sales of Tiggo 8 family.

★ Edit comments

　　At present, there are more and more young consumers in the domestic SUV market, and manufacturers have begun to further upgrade and optimize the younger models. Tiggo 8 PRO is a model born in this background, which evaluates the fashionable and dynamic design and rich configuration to attract young consumers. With different product style positioning, Chery has also made a good market segmentation of the Tiggo 8 series models to meet the car purchase needs of more people.

　　Looking at the sales volume of the Tiggo 8 family, by 2021, the annual sales volume of the Tiggo 8 family reached 166,000, and the global sales volume of the Tiggo 8 family reached 27,250 in January and February this year, up 12.1% year-on-year. In addition, in less than four years, the Tiggo 8 family has entered the country and marched overseas. At present, the global cumulative sales in dozens of countries around the world such as Russia, Egypt and Brazil have exceeded 480,000. It can be seen that the product strength of the Tiggo 8 family is still trustworthy. I believe that after the launch of the Tiggo 8 PRO model, it will bring better sales performance and product reputation to the Tiggo 8 family. (Text/car home graduated)
