　　The tornado disaster in Yancheng, Jiangsu Province on the afternoon of the 13th caused widespread concern. So, how did tornadoes form? Where and when are tornadoes prone to occur? How should the public respond? Xiao Cai, a meteorologist of Zhejiang Voice, interviewed Lou Maoyuan, the chief expert of science popularization of Zhejiang Meteorological Bureau today.

　　A sudden tornado in Yancheng, Jiangsu Province caused 2 deaths and 15 injuries.

　　Witnesses: The roofs are flying with them.

　　At about 4: 15 pm on the 13th, a tornado disaster occurred in some towns in Dafeng District, Yancheng City, Jiangsu Province. According to experts’ appraisal, the tornado is rated as EF2, with medium strength. From the video shot by witnesses on the scene, I saw a huge wind column, like a white dragon, rolling up a huge funnel-shaped vortex and heading straight for the sky. At the crossing point of the tornado, piles of ruins were left, roofs of houses were lifted off and trees were destroyed. The tornado disaster killed 2 people, injured 15 people and damaged 283 farm houses.

　　What wind is a tornado?

　　Lou Maoyuan, chief expert of science popularization of the Provincial Meteorological Bureau, said that tornado is a strong destructive convective weather and a small-scale air vortex generated under strong unstable weather conditions.

　　"Tornadoes are actually produced in thunderstorm clouds. We call them cumulonimbus clouds in meteorology, and the atmospheric environment is often very unstable. Inside this cumulonimbus cloud, there is an updraft and downward flow. When this updraft is stronger than downward flow, it will form a rotating thing, just like when we rub noodles, when one end falls to the ground, it forms a tornado. "

　　Tornadoes occur and disappear in a short time, often accompanied by strong convective weather systems such as thunderstorms, hail and heavy rain. The central wind power can reach 50-150 m/s, and the diameter is generally between several meters and hundreds of meters. Tornado intensity is divided into six grades: EF0 to EF5. The highest level of EF5 tornado has a wind speed of over 89.4m/s, which can instantly destroy houses and blow cars.

　　Where do tornadoes "prefer"?

　　Global tornadoes mainly occur in mid-latitude areas, and tornadoes occur every year in North America, Europe, Russian Federation, China, Japanese and Australian, especially in the United States, which produces an average of 1,141 tornadoes every year. In China, there are more tornadoes in Jiangsu, Guangdong, Hubei, Anhui and other provinces, among which Jiangsu and Guangdong have the most tornadoes, with an average of 4 tornadoes per year. Northern Jiangsu is a high-incidence area of tornadoes because of its low-lying and flat terrain, interwoven rivers and lakes, and the climate transition zone between subtropical zone and warm temperate zone, which is easy to accumulate unstable energy. Spring and summer are tornado-prone seasons in China, with July accounting for the highest proportion. Tornadoes often appear in the afternoon, and tornadoes that occur between 12: 00 and 20: 00 account for 70%.

　　Lou Maoyuan said: "From our point of view in Zhejiang, the average tornado is less than once a year. Because tornado is a kind of strong convective weather with small scale, sudden and strong destructive power, the forecast of tornado is always a difficult point in weather forecast from a global perspective. "

　　What can we do in the event of a tornado?

　　One word: escape!

　　Lou Maoyuan said that in case of a tornado, we should flee in the opposite direction of the tornado. If it is too late to escape, we can choose the basement or semi-basement to escape.

　　"Tornado-prone areas, if the weather forecast has a strong thunderstorm tomorrow, then you should pay attention to it, there may be tornadoes, and pay special attention to the sky from the afternoon to the evening of this day. If there is such a tornado in the distance, then the personnel should quickly avoid it from its path in time.

　　Recently, a video of a father taking his 19-year-old daughter to set up a stall to sell leek boxes caused a heated discussion among netizens. The girl in the video just graduated from high school, and now she is selling leek boxes with her father in Nanjing because she didn’t go to college. In the video, his father’s remark that "undergraduate and graduate students are not used, and it took hundreds of thousands of years and time was delayed" became a "explosive point". Some netizens thought that the father was short-sighted, and some netizens said that what Uncle said was not unreasonable. What is the story behind this video? Yesterday afternoon, Zi Niu journalist interviewed the father and daughter next to Jiangsu Maternal and Child Health Hospital.

　　The leek box booth is booming.

　　The girl is skillful in action.

　　Yesterday afternoon, Zi Niu news reporter came to Jiangsu Maternal and Child Health Hospital, and the girl’s family has not yet set up a stall. The grandmother selling sweet potatoes told the reporter that the business selling leek boxes (a kind of snacks wrapped in leek stuffing, editor’s note) was very good. Within two minutes, a tricycle drove to the door of the Maternal and Child Health Hospital, followed by a tall girl in a black jacket. This is the girl Xiao Zhao who sells leek boxes in the video.

　　Before the tricycle stopped, two or three people who bought leek boxes flocked around. The girl’s father quickly set up the stall and began to knead the dough. After kneading, he cut the dough into small pieces. Xiao Zhao rolled the dough into a round dough and put a spoonful of prepared stuffing, which is made of vermicelli, leeks and eggs. Xiao Zhao’s movements are also very skilled. The fragrance of leek eggs drifted away, attracting many customers to queue up to buy.

　　Compared with the image of pure appearance, slim figure and elegant temperament in the video, Xiao Zhao changed his style yesterday: black leather jacket with long pendant earrings, with light makeup, which is more fashionable.

　　Beautiful girls set up stalls, coupled with the fragrance of leek boxes, the business is quite good. During the interview period, the people who came to buy it almost never stopped. Even the grandmother who sold sweet potatoes next to her came to buy two, and the father and daughter could not stop. Many people buy leek boxes while chatting with their father and daughter. In addition to the leek box, the topic is very interested in the father and daughter themselves, and I ask about them from time to time. Although Xiao Zhao, who has a little Suqian accent, has questions and answers, they are extremely "refined" and never say a few words.

　　With the advantage of girls of the same age, Zi Niu news reporter proposed to take Xiao Zhao to the side for a separate interview, and the girl’s father readily agreed.

　　Girl’s story

　　I failed in the college entrance examination last year.

　　Selling leek boxes with my father

　　The girl named Zhao Yan is just 19 years old this year. After graduating from high school last year, she followed her father to Nanjing to set up a stall to make leek boxes. Zhao Yan’s hometown is Suqian, Jiangsu Province. Because she was interested in hosting in high school, she participated in the art test training for broadcasting and hosting majors at school. Last spring, Zhao Yan applied for the joint art examination of five universities, including Nanjing Art Institute, Communication University of China, Nanjing Normal University, and her final art examination score reached the score of the director major of Nanjing Normal University. However, Zhao Yan was worried that she couldn’t be admitted to the university because of her poor performance in culture class. In April after the art test, she came to her father who was setting up a stall in Nanjing to do business, and asked him to take her to try the flight attendant training of China Southern Airlines. However, after learning that flight attendant training takes four years and costs a total of more than 100,000 yuan, the father and daughter decided to give up the flight attendant training after careful consideration.

　　Xiao Zhao said: "As long as a subject fails, you can’t go to work in the end. I can’t guarantee that every major can pass. In addition, you have to find your own job. This is a bowl ‘ Youth rice ’ , work is unstable. " The father on the side also said that her daughter is almost 20 years old now and will be 24 years old in four years, which is still risky.

　　In June last year, the girl returned to her hometown in Suqian to take the college entrance examination, but her grades were not satisfactory and she didn’t get the admission notice in the end. She decided to make a leek box with her father first.

　　Zhao Yan smiled and told Zi Niu news reporter that you don’t need to learn to make leek boxes, just follow and see. But when it comes to plans for the future, the girl hesitated slightly: "I haven’t thought about what I want to do in the future. I feel that it’s not too hard to do this now. It’s good to learn a craft and earn money."

　　Netizens are hotly discussing.

　　Is it better to go to junior college or set up a stall to do business?

　　On March 13th, a video of Zhao Yan selling leek boxes with her father was posted on the Internet, which attracted the attention of many netizens. In the video, Zhao Yan’s father said that "it is better to do business than to spend more than 100,000 yuan in junior college for 4 years", which triggered questions and discussions among netizens.

　　Some netizens agreed. The netizen "Sean is a little baa" said that setting up a stall now is higher than the salary of the university. Netizen "child photographer _HAN" commented, "I agree with this father’s idea very much! Unlike in the past, most college students have low eyes and are bent on finding a good job after graduation. If they can’t find a job, they will eat at home. It is better to learn a skill. "

　　Many netizens also expressed their opposition. Netizen "If you love it now" commented that there is still a big difference between junior college and students with only high school education in a few years. Netizen "I’m an honest man" said that if I keep doing this, my vision will become narrow, and why this kind of thing becomes a topic is because it doesn’t conform to the normal development of teenagers.

　　Parental response

　　Attach importance to education, but the situation at home can only be taken slowly.

　　In the face of questions from netizens, Zhao Yan’s father explained to Zi Niu news reporter, "The person who made the video at that time asked me why my daughter didn’t go to college, and I said I didn’t get it. Then she said that she couldn’t give her a junior college if she didn’t pass the exam, so I rushed her. "

　　Zhao Yan’s father said frankly, which parents don’t want their children to be good, but they can only take it slowly and have a process.

　　"I didn’t come to Nanjing to work when I was 20 years old. I graduated from primary school. I didn’t go to school much in my life. I am bitter but I can’t let my children follow me." Father Zhao said, "I still attach great importance to education. My family has a younger son. He is in the sixth grade at the age of 12 and spent more than 20,000 yuan to make up lessons for him. After the video became popular, a media asked my daughter to go on an internship in the past two days. My daughter was a little worried about not doing well. Today, I also encouraged her to say that she would practice with reporters and teachers and learn a lot, even if she didn’t earn much money. "

　　Selling leek boxes does not have the problem of high or low occupation. According to Wang Xian, a worry-free human resources expert in the future, Zhao Yan is a sensible girl who sympathizes with her parents’ hardships in raising a family and actively shares the responsibility. In this case, experts give three opinions on the right for the reference of parents and children.

　　Please listen to three opinions of professional experts.

　　A

　　Don’t lower the possibility of the future of life to a very low level.

　　B

　　Lack of career planning is the shortcoming of current education.

　　C

　　Career planning is too ambitious, which is also not conducive to growth.
