Henan Yucheng suffered a ＂tornado＂？ Expert： It is more accurate to say that the dust wind.
CCTV News:According to China Weather Network News, it is reported that on the afternoon of March 31, 2019, a "tornado" struck the 10,000-acre pear garden in Tianmiao Township, Yucheng County, which caused a trampoline to fall, causing 18 children to be injured to varying degrees. According to experts’ analysis, the weather system that overturns the trampoline is not a "tornado", and it is more accurate to call it a dust storm.
According to the propaganda department of Yucheng County Committee, at 15 o’clock on the afternoon of March 31, 2019, the Wanmu Pear Garden in Tianmiao Township, Yucheng County was suddenly hit by a tornado, which caused a trampoline on the scene to fall, causing 18 children on the scene to be injured to varying degrees. After the incident, the main leaders of Yucheng County Party Committee and government attached great importance to it, immediately launched the emergency plan, arranged the health planning department to treat it quickly at all costs, and the relevant county leaders led the relevant personnel of the Public Security Bureau, Health and Health Commission, Emergency Management Bureau, Tianmiao Township and other units to rush to the scene to organize rescue, verify the injuries of the masses, and do a good job in the aftermath.
Judging from the live video, it is more accurate to call the weather system a dust storm when it blows down. The incident occurred in the inland area. From the video given, it was clear at that time, and there were no cumulonimbus clouds in the sky, and the occurrence range was very small. It should be more accurate to call it dust storm. Dust storm refers to a small-scale cyclone generated in the near-surface gas layer by local strong warming, which can lift dust and some small objects into the air to form a small dust column with a diameter of several meters and a duration of only a few minutes. "Dust storm" generally appears on land, mostly in grassland, desert and other places, and its scope is usually small and its destructive power is limited. Such a strong dust storm is extremely rare.
What’s the difference between a dust storm and a tornado? Although dust storms and tornadoes belong to small-scale strong cyclones, their conditions and ranges are different. Tornadoes generally appear when there are cumulonimbus clouds in the sky, accompanied by thunderstorms and strong winds, etc., with a large diameter and lasting for more than ten minutes to several hours; Dust storms generally appear on land. When they appear, the sky is clear, and the diameter is only a few meters, which lasts for a few minutes or so.
There have been dust storms in other parts of China. At about 4: 25pm on April 20th, 2016, a "tornado" occurred in the plastic sports ground in Guazhou County, Gansu Province, with strong wind. Li Jiaqi, a student in Class 3 (1) of Yuanquan Primary School who was having a sports meeting, was rolled up and then left behind. After 120 emergency medical diagnosis, Li Jiaqi was slightly injured in the back of the head, which was not serious.
