Recently, a netizen posted a video on a short video platform claiming to be driving through the Qinling Tunnel. It showed that the trees on the mountain were still dense when entering the tunnel, but when the vehicle passed through the tunnel, the mountain outside was covered with snow.

The video publisher said, "It was only after passing through this tunnel that I understood why the Qinling Mountains are the watershed between the north and the south of China."

After the video was released, the strong visual contrast triggered heated discussions among many netizens. As of yesterday afternoon, the video had been liked more than 5.5 million times.

However, some netizens soon questioned that the video should be spliced ​​together.

  The publisher’s copy is misleading to the audience

  Yesterday, Chen Wei (pseudonym), a netizen who questioned the video, told a reporter from Beiqing Daily that he has been engaged in geography science popularization work for a long time. After seeing this popular video about the Qinling Tunnel on the platform, he wanted to make a science popularization video. , tell us that such phenomena do exist in some places in the Qinling Mountains.

  During the investigation, Chen Wei discovered that the tunnel the vehicle drove into in the video was the Yan'eshan Tunnel. The tunnel is located in Chongqing and belongs to the Daba Mountain. It is far away from the Qinling Mountains and separated by the Hanzhong Basin.

In addition, Chen Wei felt that from the difference in stains on the front cover of the vehicle in the two parts of the video, it can also be seen that the two parts of the video are not in the same tunnel.

  It is reported that the Yaneshan Tunnel is located in the eastern section of Dabashan. The lengths of the left and right lines of the tunnel are 4,389 meters and 4,361 meters respectively, and the maximum burial depth is 866 meters.

Chen Wei said that the original video publisher claimed that this video was shot in the same tunnel, and such copywriting was misleading to the audience.

  The filming location is located in a series of tunnels

  In response to the doubts raised by Chen Wei and others, the original video publisher recently responded on the short video platform, "The Yan'e Mountain Tunnel belongs to Daba Mountain. The mountain range composed of Daba Mountain and Qinling Mountains is called the Qinba Mountains. I always thought that Daba Mountain also It belongs to the Qinling Mountains in a broad sense. When I published the work, I didn’t pay much attention to this controversial point. I directly regarded the tunnels in Daba Mountain as the tunnels in the Qinling Mountains, which was an intellectual mistake.”

  In addition, the publisher of the original video stated that because the shooting location was in a series of tunnels, "Without splicing and editing, there would not be that shocking feeling. I don't deny that splicing and editing was done. If you mind, then I apologize."

  A reporter from Beiqing Daily asked the publisher of the original video via private message about the specific shooting location of the vehicle driving out of the tunnel in the video, but as of press time, no reply had been received.

A reporter from Beiqing Daily noticed that the short video platform has currently made a note for the short video saying: "The original video publisher has clarified, please identify it carefully."

  A lawyer from Beijing Kangda Law Firm said that the title and text content of the video are indeed easy for netizens to misunderstand and contain irregularities.

If netizens find that there is malicious splicing in relevant videos, which is enough to cause serious misunderstandings among netizens, or even create and spread rumors, netizens can report it to the video publishing platform, or through the official website of the National Internet Information Office's Illegal and Adverse Information Reporting Center or Report to the local cyberspace department.

  Can the Qinling Mountains block the cold air from the south?

  China Weather Network posted a post on its official Weibo yesterday, providing a professional analysis and interpretation of "Qinling Mountains can really block the cold air from the south by itself."

  According to the official Weibo, first of all, the Qinling Mountains do have a blocking effect on water vapor.

The average precipitation on the southern slope of the Qinling Mountains is more than 800 mm, and the average precipitation on the northern slope is less than 800 mm.

The north slope is relatively cold and dry, while the south slope is warm and humid. From bottom to top, the south slope has five climate types: subtropical zone, warm temperate zone, temperate zone, cold temperate zone, and subarctic zone; from bottom to top, the north slope has warm temperate zone, temperate zone, and cold temperate zone. There are four climate types: , subarctic zone. Its existence not only changes the natural pattern of mainland China, but also brings about a strong "north-south difference".

  Secondly, the Qinling Mountains do have a certain blocking effect on cold air moving southward and warm and humid airflow moving northward.

When the cold air travels long distances from west to east, from north to south, and moves over mountains and ridges to get here, it also consumes a lot of "vital energy". When it reaches the Qinling Mountains, the cold air will consume more when climbing uphill, so the cold air is not strong enough. There is no "stamina" left at this point.

Even if there is cold air with relatively strong "endurance", the strength will be obviously weakened after struggling to climb over the mountain, thus causing the phenomenon of Qinling Mountains "blocking" the cold air.

  However, not all cold air can be "blocked" by the Qinling Mountains. When strong cold air strikes, it can still "break through" and affect the southern region of my country.

  China Weather Network posted a picture showing dark clouds on one side of the ridge and clear sky on the other side.

In response to this picture, China Weather Network pointed out that generally speaking, if mountains block dry and cold air, there will not be such a "clear distinction" phenomenon; on the contrary, when mountains block warm and moist airflow, warm air will appear on one side. The current rises and forms clouds, while the air current sinks on the other side and clear skies appear.

So in the picture, the side with clouds is actually the south.
